Congratulations you have purchased one of the top 12v
batteries on the market
At Battle Born Batteries we do everything we can to make our batteries compatible with all the
existing products on the market, unfortunately there are a few that slip through the cracks. This
manual will serve as a guideline to check and see if your current charger will work with your
new Battle Born Battery. Published on our website (battlebornbatteries.com) is also a list of
chargers we have found to be compatible with our batteries.
Bulk/Absorption
For your Bulk/Absorption stage, the ideal voltage is between 14.2v-14.6v. This range will allow
the battery to fully charge any higher then this and the built in BMS will send the battery into a
protect mode.
Float
Our batteries do not need to float so setting your Float voltage to 13.6v or lower will essentially
turn it off.
Equalization
Equalization is not recommended for our batteries. Most chargers will allow you to shut this
feature off or use a setting that does not use equalization. If you cannot turn off this mode then
you will need to adjust the voltage to below 14.6v
Temperature Compensation
Temperature compensation is not needed with our batteries and in some cases, may trigger
the built in BMS to go into protect mode. For this reason, we recommend that temperature
compensation be shut off or set to 0.

BMS Basic Features
All Battle Born Batteries come with a built-in battery management system (BMS). Our BMS
allows us to create one of the safest LiFeP04 batteries on the planet. To help us keep our
promise that our batteries will last for 3-5000 cycles, our BMS will put the battery into a protect
mode in the event the battery falls outside of one of the following parameters.
High voltage: 14.7v-15.0v
Will not allow any more current into the battery.
Low voltage: 9.0v-10.5v
Will not allow a discharge from the battery. (Note: many chargers must detect a voltage over
10v to send a charge to the battery).
High temperature: 135F
Will not allow a charge or discharge.
Low temperature: 25F
Will not allow a charge
High Current
The current exceeds 100 (+/- 5%) Amps for 30s or 200 (+/- 10%) Amps for 0.5s (this is interpreted as a
short circuit)
Allowable output
The BMS constantly monitors the batteries output. We have set the following parameters to
ensure our batteries maintain a high level of safety.
BB10012 BB5012
Surge: 200a for 30 seconds Surge: 100a for 30 seconds
Continuous: 100a Continuous: 60a
Note: Higher current capabilities for ½ second. In all Cases the battery recovers automatically
Cell Balancing
At Battle Born Batteries we pride ourselves on making the highest quality product that we can.
We have found the best way for us to do this is to capacity match the entire way, from the 120
cells to the 4 modules to however many batteries are in your bank just know that they have
been specifically selected to give you the best performance. A concern that some customers
have is cell balancing. We built passive cell balancing into OUR BMS so that you never have to
worry about your battery becoming unbalanced.

Installation
Our batteries are rather straight forward to install, simply connect your positive cables to the
positive terminals and your negative cables to the negative terminal. Our batteries work great
in either parallel or series configurations (up to 48v). Our batteries come standard with a flag
style terminal post. These terminals include a 3/8” hole that allows for most ring terminals to
work well with our batteries. For the best connection, we recommend either copper or brass
ring terminals.
Parallel
Multiple BB10012 may be mounted in parallel in order to increase the current capacity of the system.
When batteries are mounted in parallel, the voltage of the system does not change, but the current
limits are additive. For example, two BB10012 batteries mounted in parallel can deliver 200A
continuously and 400A for 30 seconds. Three BB10012 batteries mounted in parallel can deliver 300A
continuously and 600A for 30 seconds. Therefore, all cables and connections MUST be able to
accommodate the high currents that can be delivered by the battery. Appropriate fuses and circuit
breakers are also highly recommended to protect downstream components from current spikes and
short circuits.
Series
Two BB10012 may be mounted in series to increase the voltage of the system up to a 24V system. When
batteries are mounted in series, current capacities remain the same, but the system voltage is additive.
Two BB10012 batteries mounted in series to form a nominally 24V system should be charged using a
bulk and absorption voltage of 28.8V, and a float voltage below 27.2V.

Storage and maintenance
Storage
Storage could not be easier simply charge the batteries fully and disconnect from any charge or
discharge.
Maintenance
Battle Born Batteries require very little maintenance if any at all. If your batteries are in series
and not being charged by a multi-bank charger it is recommended that you fully charge the
batteries individually once a year. This will balance out the entire battery bank to ensure the
batteries will reach its expected life span. If your batteries are in parallel this is not necessary.
Our BMS has a built in passive balancing system that will take care of this for you.

Warranty Policy
In the unlikely event, you are having an issue with one of our batteries we have developed a
straight forward warranty policy to help answer any questions you may have.
Battle Born Batteries offers a 3 year manufacturers defect warranty from the date of purchase.
This warranty does not cover negligence or misuse of the battery. If it is deemed that battery
was used improperly, you will be subject to a $150 an hour repair charge plus parts and
shipping.
We also warrant all other complimentary products (inverters, converters, chargers etc) we sell
are free from defect for 30 days from the date of purchase. After that time it is the
responsibility of our manufacturing partners and a standard manufacturer’s warranty applies (1
year from date of purchase, unless otherwise stated by the manufacturer).
