Re: Ni-MH cells and Chevron (Re: EV digest 7078)
It's a "chemistry thing." Different brands, different quality. There are
plenty of ready NiMH packs for e-bikes that you can buy. Example:
http://www.poweridestore.com/NiMH-Battery-Packs/36V-13Ah-NiMH-Battery-Pack 3
of these would cost you $1000. This would work.
