Hello everyone,
system with 2 battery ,one 10khw with 15 cells and the other 5kwh with 16 cells , 48v
both sharing the same set up, in parallel. Problem is, the bigger one has lower voltage
compare to the the smaller one, due to 1 cell less
I be able to charge them up ok, but discharging cause some trouble
when the 10kwh still have 90% SOC , the 5kwh down to 0% and its BMS shut it down
I wanted the smaller one to keep at least 10 - 15% SOC before it turn off, by installing a
voltage disconnect device or any thing like that, so it can cut off at around 51v,
reconnect around 52v and be able handle 80-100 Amp
searching everywhere but no luck
Any one here having similar issues like mine ? and what's your solution for it ?
any device out there you can recommend ?
thanks a lot for your input
good day ppl
