These batteries were likely used as backup only. The company added 100a BMS units to each module.
You can turn them on and off by hitting the Switch button. It takes about 3 seconds to turn on and off when you hit that button.
We did not capacity test them however every battery is balanced and resting at 50.1v (3.58v per cell). Every battery on the pallet is the same voltage so it's possible these have never been cycled but we would assume they were just used for backup only then another company added the BMS to them.
The BMS has an on/off switch, RS485, Can, and RS232. There is also a bluetooth module on them. We cannot give tech support on the BMS and communications but it seems this has everything you need to communicate to an inverter. Of course, when connecting to an inverter you should always use a pre-charge resistor first to prevent spark and power surge.
