How long can a 4s 4100 lipo last?

[superek4]

Hi, I would like to know can a 4s 4100 lipo last 10-15mins race? My set up is jamming CRT 1600/2000kv medusa motor, 62/14pinion or 46/11pinion. Any advise?

No way it will do 15mins unless you are drving quite slow. 10mins may be doable, but will be close. FWIW, at the few RCM bash's I've been to, the guys w/ 4S 5000 packs were doing just shy of 15mins on their truggies. Really I would count on 10-11 mins. YMMV depending on driving style. Really you want a bigger pack to make 10, and ~6000 mah to be sure to make 15.

I hv 2 packs of 4s 5000 n 2 packs of 6s 5000. But I hv 3 heats 10mins each n 30-45mins main. That's y I need the spare 4100 for the heats
