I've been looking at some lithium batteries, they are pretty new to me as i have always used Ni-Cad and NiMh. I went to a website that sells Li chargers and LiPo cells, but am a bit baffled because of the range of cells? I am buying them for a dragonfly.

What powersource are you lot using? (and no smartarses need come up with a steampowered heli )

Cheers
