Connected up all my electronics (without VESC) went to plug in the charger and had a massive spark. And the light on the charger started flashing red, so quickly disconnected and this was the result. See picture.
So my questions are:
Would that of damaged the BMS?
Based on the charger plug is the charger fried as well?
And, not being an expert but my guess is I had the charge port wired the wrong way round?
FYI. I did plug the chargers into the port with the charger already connected to the mains? Should I of plugged into the port first then plug the charger into the mains?
Hey Rich, yes I did, I posted the results on my build feed (Little Bro Trampa build) Negative on the outside L shaped pin and the positive to the other outside pin with the middle pin unused.
Shall I try again but connect the charger to the mains last?
Oh and maybe you are on to something as it sparked when plugging into port, and soaked again when unplugging from port whilst charger still plugged into mains
There’s your problem. If you followed the illustration above, it was wired in reverse. The middle tab will need to be positive(+). Unfortunately, you probably fried your charger. We had a couple 8s batteries we accidentally had reversed and the chargers did not work afterwards.
