The TrueRC are just a good bang for the buck. I wouldnt recomend anything less that the 8000mah packs though. I have a few sets of the 8K packs and they work very well.

Aha, yes, now I see. I wasn't thinking that high in terms of mAh. The 6400mAh 7.4V 2S2P looks like it would be pretty decent for a B4/T4 sized vehicle. 96A for $80, I see your point now, haha. Two of those in a Hyper 7 would be pretty fun.

yeah, as you can see the 5S 4000 runs slower than the 4S 7400's... and the 4000 True RC pack was warm.. in less than a minute. can't handle the load. I agree with jhautz there, nothing less than 8000mAH if using TrueRC's 10C pack.
