Math help needed for converting volts/watts in solar
My real Q, is what is the best power battery to store this energy? Should I only use 8 "D" cells? Could I use a 12 v motorcycle battery?
If I use Ni-Cd batteries, is the fact that the batteries are rated at 2500 ma make any difference?
Is there a website where I can get a good feel for what batteries are good for what type of activity, solar cells, etc?
