I can't believe I'm the first to post about these.
Anyways, MA has new packs out which lay claim to a "True 150C" discharge rating. Sounds great. They are using 6500mAH cells... Raise your hand if you think they can actually support a 975A discharge.

...
Nobody?
So suddenly they're back to C ratings again. Or will there be a 14430 surge-watt rating on the 4S pack? Even if the cells
CAN put out the juice, they aren't going to do it through 12AWG wires.
In all seriousness, when I see that 4S pack start a V8 engine, I'll believe the 150C rating.
