For Shannon Knoepflein.

>From what I gather from your last post, your airplane electrical system is
28 volts. Am I reading this right? If so, two 14 volt, 17 AH batteries in
series, to make up the 28 volts, gives you a 28 volt, 17 AH (nominal)
battery - not 34 AH.

If you're putting them in parallel, THEN you have a 14 volt, 34 AH capacity
(in theory, anyway).

In either case, Hamid's caveats apply.
