I think if you wire in series you add the voltage, so it’s 48v right?
But the AH stays the same so I would still have 75Ah?

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

Does not compute. If he's running four 75ah batteries in series to
get a 48VDC battery, then he gets 75Ah.

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?

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?
