Hey..... been looking around how to figure total amp hours for a battery bank.
8 12v lead acid 90 amp hour each wired series parallel to get 24v.
I know that a parallel connection doubles the amp hours for a single ' pair ', but does that carry through for the entire system, or 4 pairs..... ?

What you really want is a comparison of watts in terms of power. Volts x amps = watts. So in your case 12v x 90A = 1080W, multiply by 8 batteries gives 8640W.
You put them in series to get 24v, and now you have 24v x 90A = 2160W for the pair of batteries. 4 pairs gives 8640W, same as before.
Hope this helps.
