Is any one out there using a Lithium Polymer battery. If so what type and size are you using? I've just fitted a 550CCA battery and am very impressed so far. They are about 1/4 the size of a normal lead acid and maybe 1/6 the weight.
Careful with LiPo Battery if not taken care of right they can be Very dangerous. I've used a lot for other thing I've had seen one blow up yet but was very close to it.
