Seems like you already know everything.they why do you ask others?
Why do you ask a question when you dont like the answer.

Hi.
I'm looking for a open source (Hardware+software) on-board charger.
emotorwerks was open source years ago but they dont give a F about open source right now
Dude non-proper charging and discharging battery cells are not noticeable in short term other than making heat or reduced capacity.
Its better to use them with tesla bms itself.
