I noticed one group of parallel cells were 1v higher than the rest, so while checking group voltages I accidentally shorted through the balance lead connector and melted the connector closed. Ended scrapping two female pin headers from an old LiPo balance lead, and plugging that directly onto the pins on the BMS.
Messed up somewhere along the line and made contact with the underside of one of those big metal bars running across the BMS.
Here’s some pictures
The pins of the balance connector are now all black and I doubt any current is going to run through that properly.
I need to know if the BMS is still functional considering part of the (solder?) is melted off on the underside of one of those bars. What are those bars even for?
