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
