So tonight I wanted to make a nice little drive just before it would be dark, so I was a bit in a hurry to connect my battery to the controller, poor visibility and me having a brain-fart led to me having the wrong battery connector connected to my controller.
I connected my 4S battery directly to the controller in reversed polarity instead of taking the right connector with 20S in the right polarity, result was a puff of smoke, some melted wires and a stinky controller, I did it right 100's of times, but now I took the wrong one unfortunately, controller is dead, batteries are still good
Could someone please help me fixing the controller, or put me in the right direction, I can solder some stuff and have a simple multimeter to measure things, but I don't exactly know what all the components are for ( or what they are )
I made some photos.
First bottom side: there was a plastic / paper sheet under the PCB and I put it in mirrorview of the PCB, you can see the burn marks, this small black thing is probably toasted ( what is it ??? )
Then top side, little red thing smells really bad ( is it a capacitor ??? ), also the shunt wires ( ?!?) look burned, at least not very shiny anymore, the rest looks pretty OK to me, but maybe I killed more components
And some molten wires, outside and inside of the controller, just my luck not enough to let the red touch the black ( big sparks for sure )
All help is very welcome
