Today tried to convert son's toy rc car, from 6x AA 1,5V batteries to a NiCd 12V. Dismantled it soldered contact for NiCd and ran perfectly fine for 30 mins. And now charged the battery and as soon as I connected it to the car something popped inside. 10 mins later found this, and wondering what is this and is it purchasable ?
Thank you in advance
