Are Zippy Lipos safe with a Castle MMM Speedy?

[MrMin]

I can understand your statement, but that is purely speculative basd on your experience. I also run zippy-h's and zippy-r's and think they are great and "believe"(as in religion) that they hold their voltage. There are zippy-h, zippy-r, zippy-ec,flightmax etc... so many flavours. You should also test the batts in lab to verify all this.
Thing is, I have verified that Patrick is telling the TRUTH. when you brake you use the battery to dump 500+ watts of power in 1-2 seconds. If the batts(or something else) cannot sink this power then the ESC will blow up in nice little smoky plastic pieces.

Actually, what i'm trying to get to is if a batt is bad then it should not trash your ESC, but that is fact because the mmm uses the batts to dump load(which is very common practice) from the esc acting like a generator when braking. I believe there should be a extra protection circuit to give the bad batts a helping hand and then bad batts just give bad performance, not smoked plastic.

Patrick is trying to offer part of the solution via a ripple monitoring solution firmware upgrade, so PLEASE dont think he is not willing to help.
