I bought a motomaster eliminator smart charger, it has reverse polarity and all that jazz, it says it's a 12 volt charger.
I am trying to charge 4 12 volt batteries for my electric bike. They are all wired together. they are soldered and I can't undo them because I don't have a solder gun. The charger didn't seem to work so I reversed the wires a few times to make sure my positive and negative were correct (black, and white wire).
The charger blew shortly after I plugged it into the wall. Is it the charger, or me. I can exchange it and get a new one, but what's the point if im going to just blow up another one?
Is this charger just not powerful enough to do what I want it to do?
Is it the charger? Or am I doing something wrong?
