Hello. You've already answered this question once for me a couple of years ago, but it was on the old forum so I can't go back and look at your answer. Sorry to have to ask again.
The situation is that my sim7000 is sharing a large 6Ah lipo pack with another device, and the other device already has a BMS circuit with LiPo charging built-in. How can I disable the charging circuit on the Sim7000? I believe you instructed me to cut a trace somewhere on the board, but it's been too long and I can't remember.
