Maybe someone here can clarify the specs of batteries. Start with mAh, does that give my batteries more capacity allowing me for longer flights? For example, say I have two batteries, both 11.1v lipos but one is 800mAh, the other is 1300mAh. What do I gain here if I have more mAh? If it is longer flight time, I am wondering since my F18 and mirage 2000 both have an 11.1v 1300mAh if I could get a 2200mAh and get longer flight time provided the battery fits in the compartment? Then what about a 15C or 20C, I don't have any idea what this spec describes. Last, I could be wrong but I think the higher the voltage, the more power the plane will have, giving it more acceleration and climb limiting you to the motor and esc limits? I know this is how it works with my 9.6v vs the 8.4v in my super cub so I imagine this is the same with the lipos.
