Default Help calculating remaining flight time with LiPo's

Hi,

I've just bought 3 cell 2100 hi-discharge Kokam LiPo's. By searching the web, I found that fully charged they are 3.7 v per cell and are considered discharged at 3.0 v per cell.

I can find the total flight time from Motocalc, but I don't know what the discharge curve is for LiPo's. Does anyone know if the discharge rate is linear? or is constant until discharged?

Example, if I check the voltage after each flight, and I find the voltage is 3.35 per cell, does this mean that there is still 50% capacity left in the batteries?

Any help would be appreciated.

Thanks for your help.

Best regards,

Wayne Miller
