4s M1 A123 cells on Mamba Max 5700?

Yeah, 2s on the esc's BEC should work great, better than a 7.2 pack.

I am going to run two packs as well then... and switch.

I thought the Villian EX was water proof? I think you can roll it, dunk, and dive it, at least that's what I thought.

So I think it should work great then, over volting it a little *Titans can handle it, in fact they are a couple turns more coils than the maxx Titans) but it will be lighter.
