Thanks guys
I think i've got it now.
I have a couple of pairs of 11.1v 3700 25c/50c, and a pair of 7.4v 4600 45c batteries, I use them in series therefore have the following configurations;
2*11.1v 3700 25c/50c (constant/burst)
Volts = 22.2
Capacity = 3700
Current = 92.5/185
2*7.4v 4600 45c
Volts = 14.8
Capacity = 4600
Current = 207
I think that's right.
Did you say earlier that you got 20 minutes racing from a 5S 5000 battery, how would a different Kv motor effect run time? (if at all), i understand driving style and the track would play a part, but do you reckon it would be reasonable for me to expect similar run times from 5S 5000 if mine has a 2200Kv motor?
thanks again
