Metal man, With bec being the reason for the 12 cell/3s lipo limit, what would be the limit w/o bec for the mamba max?

there are reports of people running 4S Lipo...

I have no idea on the voltage limit. My guess is that it might be the capacitors (25v?), but the FETs are probably rated to 50v (it's hard to tell with the heatsink on).

I'll be running 4s Lipo, and there's a chance I'll be doing that with the BEC. Since I have a UBEC anyways, I might just end up using that.

CCs gave me a reply regarding the MMM saying that its possible to run 21.6V (18 cells) on that controller and I think that its also possible to run 6s lipos.
We'll wait and see.
