These Marine durable lithium batteries are leading products for your boating pleasure. Boasting long life and lighter weight they are excellent solution for the full or part-time cruiser looking to have energy available to power the onboard equipment reliably.

Battle Born Batteries come with a built-in battery management system (BMS) that protects the cells for long-term cycling.

The BMS protects against the following conditions: 

High voltage: 

If an individual cell voltage exceeds a prescribed threshold during charging, the BMS will prevent a charge current from continuing. Discharge is always allowed under this condition. 

Low voltage:

If an individual cell falls below a prescribed threshold during discharge, the BMS will prevent further discharge. Although the battery is in “low-voltage disconnect” mode, it will still allow a charging current. (Note: many chargers must detect a voltage over 10v to send a charge to the battery). 

High temperature: 

The BMS will not allow a charging or discharging current. 

Low temperature: < 25F

The BMS will not allow a charging current. 

High Current 

The BMS will not allow a current that exceeds 100 (+/- 5%) Amps for 30s, or 200 (+/- 10%) Amps for 0.5s. After a high current disconnection, the battery will automatically reconnect after 5 seconds. 

Internal Cell Balancing

A passive balancing process is activated by the BMS at the top of each charge cycle, when the battery voltage exceeds a preset level.  This ensures that all the cells remain at the same state of charge, which helps for pack longevity and performance.

Upgrading Warning:

When upgrading to a lithium battery system from other chemistry types, such as AGM, GEL or Flooded, all charging sources must be adjusted to meet the lithium battery charging profile or replace the equipment to one that does.  Installation of an alternator temperature sensor is strongly recommended to protect the  alternator from  overheating.
