I made a light up hula hoop for my wife, it's filled with AAA size NIMH batteries for 12V. She uses it a lot and they've started to die. It's always been a bit heavy so I'm thinking of going to Li-po or Li-ion, but I don't know of any that can fit in a tube that small (0.65"). A 11.1V or a set equaling that should work. I guess I could string together tiny ones but I don't really understand these batteries well enough to modify them and still charge them. Does anyone know of a battery that would fit, or small ones that could be made into one that fits and still be charged?
