Battery question of the month

[team3six]

Nahhh, I understand the whole speed, gearing, ect. The issue is there are alot of batteries on the market, Some going as high as 10000mah but only in 7.4, I know if i go 11.1V I'll get more top end out of it. But I know I dont want to go with 7.4V 5000mah which is what i have now. I seen that SMC has a 9000mah but its a 7.4V battery. So i guess with all the speed junkies out here. I can find another brand of battery with more go and throw.
