Good point, they do look about the same, dropping about 1V at a constant 50A draw. My guess is graph #2 is A123. based on not a lot. they really do look very similar.

I guess my point though was that I'm worried about toasting my Mamba Max - and have read several times of people letting the smoke out simply plugging in a 5s pack which lead me to believe it was the initial voltage of the pack which was the issue.

Its no worries though I just powered up on 6s A123 that was fully charged last night (cell voltage was average 3.35vpc this morning) and it worked fine. My ammo 3300 didnt really like being held pinned unloaded though lol... seems to still work fine but made a funny noise. I didnt even think about the fact it wouldve been doing over 60k rpm before I tried it, a bit much from a $35 motor I think :P

Second thing is even unload just blipping the throttle on and off like that my max's heatsink got warm. on 3 or 4s it didnt change from ambient doing the same thing.

I'm surprised about the amp draw though, with my multimeter reading voltage (fairly slow refresh too) going full stick from a stopped motor made the pack drop from 19.5V down to 17V - much more than I wouldve expected for a bare motor shaft (not even a pinion!), and probably more than that anyway if I had something that refreshed more than two or three times per second.

Anyway.. my buggy is on the way, and if they dont work to my satisfaction I'll invest in some 4s 3700mah polyquest packs.

Now all I can do is cross my fingers and hope that spare parts for the lightning 2 buggy are still available once the D8 is released...
