Personally, I doubt the HECELL packs are true rated. So far I have found lots of cheap packs and plenty of expensive ones that do not hold satisfactory voltage under the rated discharges. The question is whether the HECELL packs are rated true- could they be 15C cells just rebadged? Are they still a good deal as 15C cells? Maybe even 12C?
The last "bad" pack I tested was rated 15C continuous 20C burst. The pack hit voltage cutoff at 19C and was hovering at 3.4v/cell at 9C discharge. Obviously not true rated, especially considering that the 9C discharge was a burst and not even a continuous load.

Cheers for the info. The 6s (2 x 3s) would probably not be being used to its fullest. The hecell cells I have now dont even get slightly warm in my revo. but running them seperate as 3s packs in my rustler and my crt.5 conversion.
I've only just built the crt.5 and rebuilt the rustler so havent got any proper running done yet. But the rustler is running sidewinder, ammo 36-50-3300, 14/40 gearing.
The crt.5 is running sidewinder, feigao 9L (2731kv), running 18/46.
The the battery in the crt.5 gets quite a bit warmer than in the rustler under punishment, still not too hot though - but thats after only 5-10min hard 'testing' :P I'm thinking either to pick up some 3700 polyquest's (which I understand a pretty good quality) or some PQ 5000's to be safe. My brother runs the same cells as I do, as well as the newer copper tab Hecell cells, and says they run a LOT cooler than the older cells I run. I'm thinking I might invest in some of them too.
