(Lithium Ion batteries are the larger subset and generally involve rigid walls and better charging circuits)
@nire still hard to find good ones you can trust to be safe. I'm not convinced its better to stick with Nimh.
@geekylou yeah but at least normal lithium cells cant be called explosives by cops
@nire sorry I think your better of with nimh
(whereas LiPo are in soft bags and prone to overcharging because the cheap ones have nothing protecting against overcharging and more energy per unit volume, and have soft, squishy walls)
