I am thinking of the typical HK 5Ahr 20-30C packs..Zippy, Turnigy etc. when run near their "Continuous" C rating
From what you say, the Nanotech packs are much more tolerant of that kind of use ?
The C-rates they list most RC cells at only works for RC devices, which if you're an RC car, you only get maybe a 30% duty cycle of full c-rate at most, and if you're a plane or heli, you can get loaded with the full C-rate or more for your whole discharge cycle, but you've got a 50-150mph propwash or rotorwash blasting over you the whole time, and you're not sandwiched between a bunch of other packs in a bag or whatever.
If you wanted a rule of thumb for commuter bikes that want a long healthy life, I would avoid peaking over 1/2 of what they say as continuous, and perhaps 1/4 the continuous rating as your actual continuous draw in riding.
If you're racing or something, run them at the full rated C-rate or beyond. My last race bike used 20Ah of 30-50C cells, and we pulled over 680amps in continuous dyno pulls and 100amp charging, and didn't have a lick of battery issues or heating, stayed cool as a cucumber and perfectly balanced.
I wouldn't do that with a commuter bike pack that I was counting on lasting years though.
