Gens Ace 2S Stick 50C LiPo Battery w/T-Style Connector (7.4V/5000mAh) (Type 1)
reality check: 5000mah @ 50C equals about 250amp max output OR 500 amps for the much more expensive 100c variations out there. Will your humble 300 odd gram motor require such a mountain of juice. In a word: no. If it did you'll drain the battery in less than a minute and probably have sent your ride back in time (For you young ones that's a reference to Back to the Future... google it, great movie!!)
These 50C packs are more than enough to keep up with the ridiculously over engineered over marketed and far more expensive 100C+ lipos. I average around 22 amps (4C) for a 10min race, max draws are around 100amps (20C). That's well within the battery's capability and no where near the stratospheric 500amps. Again, the motor can only consume so much power... The gensace are good quality and the fixed leads don't pop out or tarnish or break like those socket type lipos now flooding the market.
reality reminder: if you want to go faster in a straight line, buy a higher output motor or go higher in voltage. Higher C doesn't necessarily equal higher speed, only overkill.

This battery is great! The more you charge it the better it has gotten....after more than 10 balanced charge cycles I'm getting almost 40 minutes of wheelie popping and 20 foot rooster tail fun out this Castle sct sidewinder in my sc10.
