Dang! 30lbs a piece?!?! I thought li-ion batteries were supposed to be light???

I saw a thread, can't find it right now, someone spent $900 on a replacement Li-ion starter battery because it only weighed 5 lbs. I guess that's as cheap as a dry carbon hood.... Their website said it could not be used in parallel. Is this a Li-ion limitation? or just that battery.

But yes, spending $2600 on batteries doesn't make this product cost effective.
BUT IF!! the future of ESCs could put out 7-10 lbs of boost with essentially no parasitic loss and instantaneous spool available at 2500rpms (not that a stock motor could handle that)....... then even if it is $6000, you would be hard pressed to get comparable amount of room under the torque curve at that price. You'd be spending more on strengthening the motor etc.
Curious to see where this leads! I know cost comparison to other FI applications is part of the game. But this is new territory that deserves exploration.

I'm stoked we get to be part of it, and happy with Rob's conservative nature, releasing reliable products and not blowing up customers motors for speculative research.
