I've used the 2000 mah kokam 11.1 volt 15C packs in my TC4 with a Hacker C4012s (3500) geared about 10:1. I've also used 14.8 volt same pack. Those batteries on my TC peak out around 40 amps on a carpet track with rubber tires. Tops speed is 30 or 40 depending on how many cells I'm using - obviously, I'm geared very short (small pinion) so I can reduce amp draws. It makes for a very lightly TC - and because the CG is actually higher, more prone to traction rolling... but lighter so everything seems to react a little faster and crashes don't break as many parts. I don't intend on going more than 4s with my TC4. I did make a 6s pack, but I have yet to use it on my TC4. Besides, beyond 60 mph, it's pretty hard to control. Anybody interested in a Kokam 22.2 volt 2000 mah pack that fits into the stock TC3/TC4 chassis? Never used - I did take it apart and reroute the wires so it would be shorter so it wouldn't cause voltage spikes into the controller and destroy the capacitors.
