Hey guys, I had an issue when I went to charge my battery. As soon as I touched the charger connector to the connector on the battery, there was a large spark and a pop and the connector got burned out. It actually vaporized the inner positive pole of the female barrel connector.
For reference, I'm using one of these:
I removed all the shrink wrap from the battery pack and visually inspected all the wires, solder points and cells, and I don't see any damage. There are no pinched or shorted wires. The cells all look ok with no melted or discolored wrap on the cells. So I don't think anything happened at the battery. I'm wondering if I should check the BMS? I'm using a 13s BMS from Vruzend and it also looks ok. I stuck my nose against it and didn't smell any burnt electronics smell and I didn't see any scorch marks from looking in the sides. I didn't try removing the metal plate on the BMS as it appears potted to the PCB and components.
I'm not sure what to check first electrically. I'm hoping you can point me in the right direction of what to check first. Is there some way I can test the BMS to verify it's OK? The connector on the charger is melted so I can't really test the charger at this point.
Any help is appreciated.
