I ordered an item a while ago and it never came so I contacted the seller and he sent a new one. But when I got the package it was not what I ordered. I messaged him again and he resent my original item again and he does not seem to care about the item he accidentally sent me.
It looks like a cheap BMS I’ve not clue how many cells it’s for. But I don’t need it. It’s probably useless but is there anything it can be used for.
