I am to assemble Li Ion battery packs to power my boat motor. I have found batteries (Samsung 30Q, 3000mAh), racks and nickel strips for assemble. However I have difficulties finding a proper BMS system.
My plan was to make 5 modules of 12S10P , giving me approx 48V at 30Ah for each module. Then wire the 5 modules together in parallel and get 150Ah in total. Each module would than have 12S10P BMS for at least 30Ah. But the supplyer could not recommend this setup.
My mayor is mechanical engineering. I did a lot of research on battery packs but still missing out on the BMS.
What sort of BMS system am I looking for?
