Hi guys
Just start experimenting wit Li-Ion battery at my 24V system and looking for BSM for 6S Li-Ion
Anyone some sugestion please.
Until now I used 2x12V 90Ah AGM old 5/7 years and performance is crapy
Today I had for free 42V 13.8Ah VAG battery 1 year old 5WA915107
It was 12S 2P CATL 6.9Ah and I mods today for 2 x 24V banks and now I using them without BMS as test run
Than today all open and mod done Cutt cross-busbar and here I have to 2 x 24V 6S2P + connected both banks parrarelly
Ideally will be 7S2P but this is fine for testing
MPPT set to max V cut to 24.6V = 1 cell max 4.1V for now without BMS
Did small experiment with grid tie inverter 45V and nicely 1000W 35A
Tommorow will try charge to max 24.6V if Sun ? be there HaHa forecast rain and
Than if you know any good BMS 20A for li-ion please advise THX
