Question Hmm. it sounds like *I* missed something.

The Battle Born literature says that each 100Ah battery can be charged at 50A, so if I put them in parallel, I should be able to deliver 100A of current, though I'm only suggesting I go with 50A, so half the rated charge current.

Am I missing something?

Parallel charging will not be exactly balanced, so "100A of Current" would exceed the 50A rating of one battery (and it's BMS) while remaining within that limit on the other.

However, if you're going to use the AIMS at only 50A, on the bus for both batteries, you can't possibly have that problem. But why buy the AIMS, with that limit in place, when you could use a (IMO Superior) PD? I assumed that your goal was to run higher current from the AIMS, and reduce total time-to-charge from a generator.
