I got a 12V starter box used and am having a pretty weird problem with it. It works fine, but when I try to charge it, it kills the charger. I tried a new battery and charger and the same thing happened. Now I can take the battery out and charge it and it will work fine. No wires on the inside look damaged at all. Nothing in the charger smells or looks burnt. Anyone have any ideas?

Most standard hobby chargers won't charge a 12 volt lead acid battery. It requires a constant voltage, variable current charge, whereas most other battery types you use in this hobby are a constant current, variable voltage charge.

You either need a peak charger that can do it (Super Brain 977 is what I use), a car battery charger, a 12 volt wall charger, or a float charger.

I was using a 12v wall charger. It is really weird. It will charge the battery when it is out of the starter box, but blows up when it is in it.

Check to make sure the plastic washers are there on the banana plug jacks. You need one on each side, and there should be 2 kinds of washers there, you need one of each on each side.

Well I figured it out. The jackass that sold me the box had the positive lead to the BLACK post and the negative to the RED post! This officially marks the last time I buy used equipment! It just isn't worth it.

Thanks for your help guys!

It obviously made sense to him. Either that or he'd never bothered to charge the battery through the terminals.

It's Nitro or it's Nuthin!
