Was building my battery back over a couple days and recently noticed my bms fried itself. I’ve included one picture of the fried bms and a pic of the non-fried one.
I’m assuming something got shorted via balance leads since I left them connected to the bms while I was working on it. As a result one of my parallel groups got discharged to 3.0v and another to 3.4v. The rest of the parallel groups hover around 3.6.
The reason for my post is to ask how this might have affected my cells and whether it is safe to continue to use them or not.
This is my first post on here so I’m not sure if this is the right place to post.
Thanks in advance!
