I need to power a water pump at a cabin in a remote location charged by solar panels and a lead acid batter would be impossible to pack (by me anyway) in due to it's weight.
The wieght of 20 AAs is nothing. I cannot go higher like D cell because I am in Canada and all batteries higher than AA have the same NiMH (what a scam).
By simple measurements - each AA NiMH battery is 2500mah or 2.5 AH x 20 = 50 AH but something tells me this will not be the same as a deep cycle lead acid battery?
Also, once they are all hooked up properly in parallel + series to equal 12 volts, can they be charged in a bundle like this?
Any help on this is greatly appreciated.
