i currently run 6s on my MMM, but just doing my homework for when the new MMMHV is available... So i have no data logger at the moment, but i will make sure to get one when the new ESC arrives...
I am definitely using the most out of my current lipos... thanks to my xxl chassis and the weight at the front of the tvps, i can put all the power down without much chance of wheelies... and the new centre diff also helps keep the front down too...

Honestly, i have seen graphs from a data logger, and dont really understand what they are representing, but i guess i will pick that up as soon as i get one..
edit
reno - i believe there is a break somewhere... i do not have a multimeter so i cant determine where the break is, but someone mentioned that the neg side was not looking so great and i should just reflow the solder... So ill do that tonight and i am hoping that sorts my problems... FINGERS CROSSED..
