So each pack is 4S 4500mah?
If that is correct (I am just asking for clarification) then you would be able to supply ~95 amps continuous and ~160 amps burst....
(Please correct me if I am wrong)

I have never run a MMM but I think that is on the lower end of what the MMM would like. But I think it would work.

Someone with MMM experience please confirm or deny my statements
