Battleborn Battery Bank
No maintenance, stable power and built-in protection is offered by the 4 Battleborn batteries mounted in floor of the trailer. The individual batteries are wired to a 24 volt battery bank and a fuse is added in the middle even when a direct shorting of the 4/0 gauge cables is the fuse ensuring no problems.
The battery bank have 5 kWh of useful energy and is often drained to 20% State of Charge (SoC) and sometimes to empty by running a computer that generate Crypto currency in the summer. This setup is to test the longevity and stability of built-in BMS, the batteries have also been exposed to freezing temperature for many days and handled it fine. No charging was allowed when below freezing, the battery still supplied power.
