Hi Kasey.
To upgrade to 48v, you'll need another 12v10ah battery, either a 12v charger for it, or a 48v charger for all four, and since it sounds like your stock controller is hosed already, a new controller. You'll also need some place to put the xtra battery. I raised my stealth's battery box for that.

has a good rep, and sells the $35 and $40 48v controllers that will work with the stealth's brushed motor (most crystalyte controllers are for brushless motors). The closest battery option I saw was a 12ah battery which will work if you charge it separately with a 12v chargers.
I got my 12v charger and extra 10ah battery from:

Do you need a new controller in a stealth 1000W to upgrade to 48v or will the stock one handle the voltage?
The stock controller will handle it. I've got an extra if you want to buy it from me. Email me at natenathan [at] hotmail.com. I had 4 12v 12ah batteries running through the stock controller for at least 5 months. I'm running 60v through an unmodified yk42-4 controller right now. I have plans on running 72v with a modified yk42-4 with bigger capacitors, mosfets, diodes, and a larger resister. A 24v controller will handle 36v too. Just try it.
I bent my wheel, broke my trans, and blew my motor. Now I cry a lot.
