LifepO4 battery recommended max charge current in a series-parallel
Current is measured in Amps. Ah is Amps x Time. So lets use the proper terminology. When 2 x 24V batteries are connected in Series the Voltage doubles to 48V and the Ah rating of the resultant 2S battery pack stays the same, 100Ah because current is flowing through both batteries at the same time, it has no were else to go.
Parallel connecting different Ah batteries.
battery X and battery Y are single cells connected in parallel. they have the same voltage when fully charged battery x has a capacity of "C", Y has 1/2 the capacity of battery X, so Y is "C/2" a load of C/2 is pulled from the parallel battery bank, or C/4 from each battery(as long as each can provide the current!).
