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.
