8-10 Minutes equals to 13.2-16.5A (with usefull 2200mAh) over the whole run = 240-300 Watt (3V under load per cell). At this overall discharge rate your A123 cells shall live a long and healthy live. I use my 9s1p A123 cells with an overall discharge rate of 15A @ 27V = 405 Watt in a 10.1lbs (4.6Kg) Buggy/Truggy hybrid when running on a track and geared for 38mph. When discharged in 6-7 Minutes (19-22A) they will warm up somewhat (55°C / 131°F) with outside temps slightly below 90°F. I know of one Rc-Helicopter guy who discharges 7s1p in under 5 Minutes ... heating them up to 80°C / 176°F ... recharging them as soon as he ends his flight at this hi temps @ 8A ... they also take this kind of abuse and do perform better when kept at relatively high temps.

>get some video up man. I wanna see how it runs on the 1p a123

+1 ;-)
