Uh. I think you have series and parallel backwards.

If you wire 4 batteries in series that's 12v =)

Does not compute. If he's running four 75ah batteries in series to

Oh you're complicating the question...I think.
The capacity from one 75ah is simply quadrupled in your case.
You have 300ah. When you add another (identical) battery you're
adding capacity/runtime linearly.

Yeah, the Alpha will calculate this, but I need to know how
to calculate Peukerts Number.
Or if I’m just running a simple series of four 12v for 48
volts is 1.1 just the default I should use?
Do I add up all the four 75ah ratings per battery and use
that as the rated battery capacity number at 300ah?

*Subject:* Re: [AFMUG] Peukert Number
Peukert's formula, T = C / In (or C = T * In), where C is
theoretical capacity (in amp-hours, equal to actual capacity
at one amp), I is current (in amps), T is time (in hours),
and n is the Peukert number for the battery.

Been reviewing my site capacity/UPS/Batteries.
Our Alpha's have a Peukert Number to help identify and
tweak capacity in remaining amp hours.
Can someone give me the short of this calculation?
That is, if I have four 12v batteries run in series that
are 75AH each?
