Hello, I'm translating to google translator because I don't speak English. I am very sad.
I found a bms that I took off the jet ski and cannot access maintenance.
Can I use it for my power wall?
Found out that 14s 20p 200A peak bms.

Looks like it is a combination of a BMS and DC-DC step down converter. Does not seem, that the power electronics for switching battery current is on board. This will probably be done just by a contactor signal. But the traces look quite corroded. Even if you could figure out where to connect balance and signal wires to the battery, would you really want to trust this thing to watch about the most important part of your system?
