12.8v 50ah Lifepo4 4s Battery - Needs BMS Batteries The BMS with relay installed

The BMS with relay installed in these may not work right but we know the cells inside are balanced and have good voltage

You need some sort of insulation between the cells to ensure they do not touch

Balance connections are straightforward since each series group has bolted terminals

You'll see in the middle of the chart the amps will go back up to 20 as the voltage drops until it reaches 2
