Dual Brushless?

Well, each 3s2p pack is capable of 84A continuous. I think using them together should be more than enough. You have two choices though: 1) Run a 3s2p pack per MM/motor or 2) charge and balance each sop they are exactly the same level and run both in parallel for 3s4p total (168A) and Y that pack to both MMs. This assumes each pack has seen close to the same use and cycles and age.

You gotta figure each pack is good for ~900w. Two packs should be good for ~1800w. That's 2.4HP.
