I’m shopping the Phoenix 24V/25A charger, the specs on the 2 page data sheet list the battery capacity at 100-400 Ah, the user manual lists it as 100-200Ah. Is the difference because they are summing the 2 outputs? I want to charge (2) 24V banks that combine at about 250Ah,
( 900CCA/7.25 = 124 Ah). These banks are use for engine start and bow and stern thrusters, all short duration loads.
Its an older charger. Lead acid batteries should be charged with at least 10% capacity to avoid ruining the bank.
So the number of chargers chosen would be based on thr capcity and keeping in a good amp range.
Thanks for your reply, but it doesn’t answer my question: why the difference in the specs?
BTW, these are AGM batteries. I think what you are saying is each bank needs about 13A minimum of charging current, correct?

At least 13A each yes.
The 25A is the max the entire charger outputs.
