with an e it is!

Yeah, my motors label also states they will run between 4.5volts and 15volts. The biggest problem is finding a speed control that will handle the higher voltages.

I'm used to RC car stuff, running 2S or 3S type batteries. I think 4S Lipo would be a little too high as a charged lipo is over 4.2volts per cell.

But these 4S Lifepo cells http://www.hobbyking.com/hobbyking/s...dProduct=14067 seem like a good replacement for the 12volt nicads/nimh. From what I have read they are the A123 cells that were used in the dewalt power tool range, they are stable and less prone to bursting into flames.

I need to do a lot more reading, but they also appear to have a 2000+ life cycle? However, you'd need to buy new chargers
