At our last clubrace (indoor, carpet), a 2s-lipo-guy was as fast as the 4.8V modified drivers.
Here is a list about the real differences between 1s and 2S Lipo...
1. 1s 4000mAh has as much energy as a 2S 2000mAh pack
(3.7V x 4000mAh = 7.4V x 2000mAh)
2. average battery power of a 1s 4000 is the same as 2S 2000
3.7V x 4Ah x 60min /8min = 111W
7.4V x 2Ah x 60min /8min = 111W
3. Cause of the higher average current, 1s Lipo generates more heat (cables, ESC, etc).
Power, that goes away through heat = I x I x R
So, twice current generates quadruple heat.
4. 1s needs a reciever pack or voltage booster
