I grabbed this plot off the KOKAM USA site (added later--did I forget to attach it??, here it is ). I thought it might be interesting for people. As I look at I am trying to understand some of the significance! It is a plot of the battery output voltage as a function of used capacity. Several traces are shown for different discharge rates (up to 20C). I note this is for a 4800mAh 20C KOKAM single cell lipo. I think they call this an "ultra power" cell design. It looks very similar (maybe a bit higher capacity) to what a lot of people are using in their multi cell packs.
One other point is they say the temperature is 23oC. I am not sure if that is room temperature or battery temperature. If it is battery temperature, then they must be providing a fair amount of cooling! From the 20C trace, the power dissipated in the battery is (estimated at 2Ahr point by the (voltage at 1C-voltage at 20 C)*96A~31 watts! Note again this is a single cell. Also this is energy not going into your prop! I note from the AXI 2826/10 spec, maximum efficiency of the motor is between 20-30 amps. This would be equivalent to a 4C to 6C discharge rate for this battery. Since I don't have an AXI motor, I am not sure how people are propping them But it would seem reasonable to prop them somewhere in this range for level flight. I will say I have only flown electric RC (not CL yet) with brushless motors and Lipo batteries, so I could be all wet here.
One obvious thing, if you are aware of your average discharge rate during a flight (10C for example), then you can see how much the voltage drops vs used capacity. If you have a time with throttle control, you could set the throttle to allow some headroom for ramping it up (using the JMP-2 timer) or for the level in governor mode. As I said, I am not positive how to use it yet.
