Battery Draw Bogus Math? Peukert UPDATE 2
Update- 11 Oct 20, Update 2- 12 Oct 20 Thinking one 100AH battery that can be drawn down to very low SOC gives you nearly the same "usable AH" as two regular AGM or Wet batts, as seen advertized, ...

Are you trying to figure out how many hours of use at 5 amps
Or how many hours at 10 amps
10 amps from two batteries will be the same time as 5 amps from one battery , for the same SOC
5 amps from two batteries will go 32 hours for the same 20%: SOC
Or possibly 20 hours instead of 16hrs for the 40% SOC because of reduced perkuet effect
The amp rate is so low that perkuet is really not much of a factor, that comes into play at high amps decreased capacity, not much amphr capacity gain at low amp use
