I’m hoping some of you pros can help me here.
About a week ago I plugged my charger into my board while it was standing against the wall. Obviously, with my luck, the board fell over and the charging port (gx12-3pin) sheered right off (on the charger side, the board connector is fine)
So I hit up Amazon and purchased a new connector for the charger.
I then proceeded to solder on the gs12 connector, making sure the positive and negative cables went to the right pins. This was double, and triple checked by a mutlimeter.
As soon as I plugged in the charger (charger was not in plugged into an AC outlet) a surge from the battery went back to the charger and blew the pin out of the connector.
I assumed I shorted something so I re-did the job again this time making extra sure I had no shorts.
I even opened up the charger, and used a volt meter to check continuity directly from the PCB allll the way back to the xt30 connector where the battery plugs in. No shorts of anykind were found and continuity all the way through is good!
Plugged the battery into the xt30, and the same thing happened again!
I’m pretty sure all the wiring is good, I mean there’s really no errors to be made it’s a simple red and black wire going into the gx12.
So my question is, could the charger or bms have been damaged when the board fell?
Is there something else I should be looking at?
PS- This is a stock BKB DUO.
