General Ballistic EVO Questions

Q. What are the advantages of EVO batteries?

A. Click to reveal:

Ballistic EVO batteries have several advantages over conventional lead-acid batteries.

  • The primary advantage is weight. An EVO battery can be as much as 17lbs lighter than the stock battery. This will help your powersports vehicle accelerate faster, stop quicker, handle better, and get better gas mileage.
  • EVO batteries are powerful. Because of the amazing energy density of our EVO Lithium Ferrous Phosphate (LiFePO4) technology, EVO batteries can deliver more energy than a lead-acid battery of similar size and weight.
  • EVO batteries are more efficient than a lead acid battery. EVO batteries have a static discharge rate of only 10% per year. A lead acid battery self-discharges at a rate of roughly 1% per day. An EVO Battery has a cycle life of more than 2000 cycles versus a conventional battery which has a cycle of roughly 600 cycles. All of this means your battery will last longer.

Q. What are the disadvantages of EVO batteries?

A. Click to reveal:

Although Ballistic EVO batteries have several advantages over a conventional lead acid battery, there are also some disadvantages that should be considered before you purchase.

  • EVO batteries sometimes cost as much as double what a conventional lead-acid battery costs. If you are looking for a cheap OEM replacement battery and performance is not a concern, a lead-acid battery might be the best choice.
  • EVO batteries do not perform as well in cold weather as a conventional lead-acid battery. If you frequently use your powersports vehicle in cold weather (less than 32°F / 0°C), a conventional lead acid battery may be the best choice. You can watch our cold weather starting procedure video here and read more about the cold weather characteristics here.
  • Although EVO batteries have incredible energy density and they can burst more cranking amps than a conventional lead-acid of similar physical size, they have less amp/hours. Amp/Hours is the ability to deliver a small amount of power over a long period of time. This means that if you typically use electrical accessories when the vehicle is off, a lead-acid with more amp/hour capacity might be a better choice.
  • Watch our video on the advantages and disadvantages of LiFePO4 batteries.

Q. What is the difference between EVO2 and EVO3?

A. Click to reveal:

EVO2 and EVO3 use the same Lithium Ferrous Phosphate (LiFePO4) cell technology, but the difference is in the applications. EVO2 is built to be the smallest and lightest solution. These are perfect for applications in which weight savings is the primary factor like racing or custom applications. EVO3 batteries are built to be as close the OEM size as possible, while offering multiple power output options and terminal locations. This means easy installation and more power options in a lightweight package with additional cranking power over the stock battery.


Q. Can I use an EVO battery to run additional electrical accessories?

A. Click to reveal:

The Ballistic EVO batteries are designed to be used as starter batteries. EVO batteries typically have much higher cranking amps than the stock battery, but less amp/hours. What this means is that if you have a lot of additional electrical accessories that draw from the battery when the vehicle is not running, an EVO battery will discharge quicker than the OEM lead-acid battery.


Q. How is the Ballistic EVO battery different from other Lithium batteries?

A. Click to reveal:

The Ballistic Performance Components EVO battery uses custom made cells, cases, and connectors that are made specifically for the purpose of starting powersports vehicles. This is not a collection of generic commercially available parts wrapped in shrink wrap. This is a purpose built product designed, engineered, and assembled in the USA by an American company with over 20 years of professional motorcycle racing and manufacturing experience. We have made significant investments in materials, production capacity, and engineering that allow us to sell a lighter, more powerful battery at a better price and at the same time offering an exceptional 3 year pro-rated warranty.


Q. Cold Cranking Amps vs Burst Cranking Amps?

A. Click to reveal:

Cold Cranking Amps is an SAE (Society of Automotive Engineers) standard used to measure the output of a battery at 0°F (-18°C) for 30 seconds to half of nominal voltage (7.2v). This rating is not applicable for Lithium Ferrous Phosphate (LiFePO4) battery for several reasons. The primary reason is EVO batteries are not meant to be used in a subzero environment. 0°F (-18°C) is the absolute limit of the EVO batteries’ operational environment. The second reason is the EVO battery’s unique ability to generate its own heat energy and lower its resistance. This is done by putting a draw on the EVO battery, making it stronger with each draw instead of weaker like a traditional lead-acid battery. The cold cranking amp rating does not take this characteristic into account. In the real world of powersports starter batteries, it is very uncommon to attempt to start a motorcycle for 30 seconds at 0°F. This is an unrealistic rating that does not apply to LiFePO4 batteries. We do not give our batteries a cold cranking amp (CCA) rating, but rate them in burst cranking amps based on the environment they are intended to work in. Burst Cranking Amps is the actual amp output at 70°F (21°C) for 5 seconds. We feel that this is a better representation of the output of the EVO battery in the real world.


Q. Cranking amps vs amp/hours?

A. Click to reveal:

Batteries typically are categorized by two different ratings. Cranking Amps and Amp/Hours. These two ratings are similar in that they describe the amount of amps a battery can deliver, but they are distinctly different in the real world and one cannot be used to predict the other. Cranking amps is the ability of the battery to deliver a large amount of current over a short period of time and then recover. This rating describes how effective a battery will be at starting an internal combustion engine. Ballistic EVO batteries have very high cranking amps for their size and weight and are perfect for starter batteries. The Amp/Hour rating is the ability of the battery to deliver a small amount of current over a long period of time (amps x hours). This rating describes how effective a battery is at running an electrical accessory over a long period of time such as an alarm or a radio. Although Ballistic EVO batteries have very high cranking amps compared to the OEM battery, they have relatively low amp/hour capacity. If your powersports vehicle has several electrical accessories that draw from the battery when the battery is off, a Ballistic EVO battery will discharge faster than the OEM battery.


Q. How do I ship your battery?

A. Click to reveal:

All EVO3 and most EVO2 batteries are UN 38.3 certified and can be shipped via air or ground freight as unregulated lithium batteries. The exception is the 16 Cell EVO2 (100-013) and 16 Cell HD EVO2 (100-014). These batteries can only be shipped via class 9 hazardous goods ground shipping regulations. All EVO batteries must be shipped with the warning label located here on the outside of the box. The MSDS sheet for EVO batteries is located here. If you require any other shipping information, please contact us at info@ballisticparts.com.


Q. What is a pro-rated warranty?

A. Click to reveal:

A pro-rated warranty is very common in the automotive/powersports industry for wear items like batteries and tires. The standard battery warranty in the industry is one year for a free replacement. We wanted to offer something more. We also offer a free replacement warranty for the first year of ownership if the battery suffers a manufactures defect. We go one step further and after the first year of ownership we offer a 50% discount from retail on a replacement battery and in the third year we offer a 25% discount off retail on a replacement battery.

Charging Questions

Watch our video about the different types of battery chargers.

Q. My battery stopped working, what do I do?

A. Click to reveal:

If your EVO battery will not start your bike, then the first step is to charge it! EVO batteries have a lot of special qualities, but at the end of the day, they are just batteries and they can become discharged for several reasons, just like any other battery. We recommend checking voltage first. The minimum charged resting voltage of an EVO battery is 13.2 volts. If your battery is not at least 13.2 volts then your battery is not charged. You can view the charging instructions here. The best way to charge an EVO battery is with a Ballistic EVO charger. After the battery has been charged correctly, let the battery sit for a few hours. It should settle to between 13.7 volts and 13.2 volts.


Q. Do I need a special charger?

A. Click to reveal:

No, you are not required to purchase a special charger. Most chargers will re-charge an EVO battery adequately, but because of the vast number of chargers available and the huge variance in charging specifications, the only battery charger we recommend is one of our EVO chargers. The EVO Advanced Charger is designed specifically to recover, charge, and maintain an EVO battery. The EVO Professional BMS Charger has the added functionality of utilizing the BMS port on the EVO battery to “balance charge” the EVO Cell Pack. Both chargers use special charging algorithms to charge your EVO battery in a manner that can greatly extend its life. Conventional chargers designed to charge conventional batteries may stop charging at the lower lead-acid specific charging limit of 12.8 volts. Some lead-acid specific trickle chargers may constantly charge which would leave an EVO battery at its voltage limit of 14.4v. This could cause reduced life over time. If you would like to use a maintenance charger, the EVO Advanced Charger is the best solution. EVO Advanced and EVO Professional BMS chargers always charger your EVO battery correctly, every time.


Q. Overcharging and Undercharging?

A. Click to reveal:

The primary risks of using an unknown charger designed to work with other battery technology is the risk of overcharging and undercharging. Overcharging is when the battery is charged at a higher than recommended charging rate or charged for too long without regulation and is allowed to be charged over 14.4 volts. The byproduct of overcharging is heat and cell chemistry breakdown. EVO LiFePO4 batteries are extremely sensitive to being overcharged and because they charge so quickly, it is easy to overcharge them when using the wrong equipment or with a defective charging system. Undercharging is the simple act of not charging the battery with enough energy. This typically happens when a lead-acid specific charger is used and that charger shuts off at the full charged limit of a lead-acid battery, which is 12.8 volts. If your lead-acid based charger will not charge higher than 12.8 volts then it will never fully recharge an EVO battery.


Q. Will these batteries work with a stock charging system?

A. Click to reveal:

Yes! EVO batteries work with all modern charging systems as long as they are functioning correctly. If you have a question as to whether your charging system is compatible with an EVO battery, we sell a very simple charging system/battery tester that will test the battery and your charging system all at once. The EVO Tester is located here.


Q. What do I do when I store my bike?

A. Click to reveal:

EVO batteries have an extremely low static self-discharge rate of less than 10% per year. This means that while sitting with nothing connected to it, it loses only about 10% of its capacity over a year’s time. If you are going to store your bike or battery for an extended period of time (more than month), then the best course of action is to simply disconnect the battery and let it sit. If you leave your battery connected to your bike and your bike has a parasitic draw it will drain your EVO battery down to the point where the battery could become damaged. If you would like to leave your battery connected to the bike while in storage then we recommend the EVO Advanced Charger and the EVO Health Monitor. The EVO Advanced Charger has a special maintenance mode designed specifically for EVO LiFePO4 technology and the EVO Health Monitor uses 4 LEDs to give “at a glance” battery state of charge.


Q. Can I use trickle charger?

A. Click to reveal:

Yes, you can use a trickle charger to charge an EVO battery, but we only recommend our EVO Advanced Charger for use as a battery maintainer. Some lead-acid specific trickle chargers/maintainers apply a constant voltage which keep the quick charging EVO battery at maximum voltage all the time. This can damage the cell chemistry over time.


Q. What is a parasitic draw?

A. Click to reveal:

A parasitic draw is an electrical draw on the battery that occurs while the vehicle is switched off. Most parasitic draws are very small (like a clock) that is measured in milliamps. These parasitic draws are so small that it would take an extremely long time to have an effect on the battery. We are primarily concerned with large parasitic draws like alarms, immobilizers, GPS units, aftermarket lights, radios, or heating units that can draw a large amount of energy from the battery while the vehicle is off. A large parasitic draw from your vehicle will have a more dramatic effect on an EVO battery versus the OEM lead-acid battery with large of capacity of amp/hours. If your vehicle has a large parasitic draw then you would either need to disconnect your EVO battery or connect the EVO battery to an EVO Advanced Charger if the vehicle is going to be stored for a significant period of time.


Q. How do I test these batteries?

A. Click to reveal:

The easiest and best indicator of the health of your EVO Battery is to check voltage. Minimum voltage is 13.2 volts. If your EVO battery is not at least 13.2 volts, then the first step would be to charge the battery. The EVO Professional BMS Charger connects to the BMS port and is an excellent tool to diagnose potential battery problems. The EVO Advanced Charger has a diagnostic function that it performs at the beginning of every charge cycle. We offer the EVO Health Monitor Charger Lead that works in conjunction with the EVO Advanced Charger. This lead give a state of charge indication every ten seconds and connects to the EVO Advanced Charger for recharging. Finally, we make the EVO Tester which can be used to test the EVO battery, the starting system, and the charging system. If you have any issues, please contact our customer service professionals at info@ballisticparts.com.


Application Questions

Q. Which EVO battery is best for me?

A. Click to reveal:

We have a complete Application Guide that will give you a recommendation based on the year, make, and model of your vehicle. If you have a unique application, please email us at info@ballisticparts.com and we would be happy to help. When you look up the correct battery in our application guide, you will be given three different options. EVO2 represents the smallest and lightest option. This may require some modification to install on your vehicle. EVO3 is the option closest to the OEM sized battery and OEM terminal locations. We also display an EVO3 “Upgrade” part number for most applications. This is the same size as the standard EVO3 recommendation, but with even more burst cranking amps for modified vehicles or frequent cold weather use. Please note that the EVO batteries are NOT OEM replacements so some modifications may be required for installation.


Q. Can I use this battery in a Harley?

A. Click to reveal:

Our 16 Cell EVO2 and 16 Cell HD EVO2 batteries work great for smaller displacement Harley applications. We make EVO3 models EVX20L-16, EVX20L-24, and EVX30L-24 that come in OEM sized cases. The EVO3 models will fit in the OEM battery box with minimum modification. The biggest issue with using EVO batteries in Harley-Davidson applications is the OEM alarm that is a major parasitic draw. This parasitic draw will have a more dramatic effect on the EVO battery than the OEM battery. Although the EVO battery is able to burst more cranking amps than the OEM battery, they have much less amp/hours than the OEM battery. This characteristic should be taken into consideration when purchasing an EVO battery for your Harley-Davidson application. If you purchase an EVO battery for your Harley, we highly recommend using the EVO Advanced Charger and EVO Health Monitor to maintain the battery when not in use.


Q. Can I use this battery for an application not found on your website?

A. Click to reveal:

Sure! We have a great number of customers who use our batteries with success in an amazing number of varied applications. We designed our batteries to work as starter batteries in powersports vehicles and our warranty only covers applications covered on our website. If you have an application that is different from what is listed on our website, the EVO batteries might work, but would not be covered under our warranty. If you have any questions about your unique application, please don’t hesitate to contact us at info@ballisticparts.com and our technical staff would be happy to work with you.


Q. Do these batteries work in cold weather?

A. Click to reveal:

EVO batteries work best above 32°F (0°C) and they do not work at all below 0°F (-18°C). If you plan to use your powersports vehicle below freezing, you should consider exactly how an EVO battery will work at that temperature. When using an EVO battery in cold weather, engine cranking speed will be slow at first, but speeds up with successive attempts. The colder it is the longer it takes. When using a lead-acid battery engine cranking speed is highest initially, then it slows down. The colder it is, the sooner that happens. Why? The chemical reaction within an EVO battery quickly creates heat within the cells; raising the voltage and thus the ability to deliver higher cranking amps after some seconds. The chemical reaction within a lead-acid battery is slower, by the time the cells heat up the voltage (charge) remaining may be too low to make a difference. We have created a video located here to illustrate this starting procedure.


Q. Can I mount these batteries in any direction?

A. Click to reveal:

Yes! You can mount the batteries in any direction. The chemistry inside the EVO battery is a solid so there is nothing to leak out. As long as the battery is mounted securely, isolated from major vibration and direct heat then EVO battery can be mounted anywhere.


Q. Can I leave my BMS plug connected to the battery?

A. Click to reveal:

The BMS port is live with the same voltage as the main terminals, yet the connections are much closer together. In order to avoid shorting out the battery with water or debris, we recommend keeping the BMS port covered, free of moisture and debris. The BMS port should be uncovered and the BMS cable only used when charging the battery.


Q. Do EVO batteries come in a 6 volt configuration?

A. Click to reveal:

Sorry, we do not make a 6 volts EVO Battery.


Q. Should I use an EVO battery in a vintage bike?

A. Click to reveal:

EVO batteries are more sensitive to variations in charging system outputs than lead-acid batteries with a higher amp/hour values. Vintage bikes from the late 60’s to the early 80’s sometimes have charging systems that are not as consistent as modern charging systems. These primitive charging systems sometimes have voltage outputs that exceed or are below the voltage limits of an EVO battery. We strongly recommend using the EVO Tester to check compatibility before using any lithium battery in a vintage bike. EVO batteries are NOT compatible with positive ground systems.


Q. Can I use EVO batteries in series or parallel?

A. Click to reveal:

Yes. We have a great number customers who use our batteries with success in series or parallel configuration. That being said, we designed our batteries to work individually as starter batteries in powersports vehicles and in turn extend a warranty to batteries used in this manner. If you have any questions about using our product in series or parallel please contact us at info@ballisticparts.com and our technical staff would be happy to work with you.


Q. Can I use an EVO battery in a Watercraft?

A. Click to reveal:

Yes! EVO batteries work great in watercraft! They are light weight and if disconnected from the ski, will sit all winter and won’t go dead. There are a few things to consider when using an EVO battery in a watercraft. The EVO battery is water resistant, but if submerged underwater can become damaged from either water intrusion or from simply shorting out. We highly recommend the use of dielectric grease in the BMS port if the battery is going to be used in extremely wet environments. If the water is allowed to sit in the port for a long period, the port will short out the battery and it would not be covered under warranty. The other consideration is to mount the EVO battery securely, in a manner that isolates the battery from the extreme jarring and impacts common in personal watercraft.


Q. Can I use an EVO battery in a snowmobile?

A. Click to reveal:

We do not recommend EVO batteries for snowmobile applications. One of the disadvantages of EVO LiFePO4 batteries is their cold weather performance. EVO batteries work best above 32°F (0°C) and they do not work at all below 0°F (-18°C). If you plan to use your powersports vehicle below freezing, you should consider exactly how an EVO battery will work at that temperature. When using an EVO battery in cold weather engine cranking speed will be slow at first, but speeds up with successive attempts. The colder it is the longer it takes. When using a lead-acid battery engine cranking speed is highest initially, then it slows down. The colder it is the sooner that happens. Why? The chemical reaction within a EVO battery quickly creates heat within the cells; raising the voltage and thus the ability to deliver higher cranking amps after some seconds. The chemical reaction within a lead-acid battery is slower, by the time the cells heat up the voltage (charge) remaining may be too low to make a difference. We have created a video located here to illustrate this starting procedure.


Q. Can I use an EVO battery in a car?

A. Click to reveal:

We have a great number of customers using EVO batteries in automotive racing applications. Although the EVO battery was designed to work in powersports applications, the EVO battery works just as well in small displacement race car applications, but because of the varied number of applications and the inherently harsh environment of automotive racing, we do not offer a warranty for EVO batteries used in race cars. We do not recommend EVO batteries for any street car applications do to the potential for large parasitic draw which could discharge the battery quickly.


Q. Water resistant vs water proof?

A. Click to reveal:

The EVO battery is water resistant, but if submerged underwater can become damaged from either water intrusion or from simply shorting out. We highly recommend the use of dielectric grease in the BMS port if the battery is going to be used in extremely wet environments. If the water is allowed to sit in the port of a long period, the port will short out the battery and it would not be covered under warranty.
