Is there any tool that can be used at the field to tell the batteries capacity besides recharging.
A shovel.
I fly and recharge every fourth flight even though I think I can get 7~8 flights out of them.
I was lucky once, a cell died and I noticed the servos where slow so I checked the voltage 3.3v, the radio worked, but the servos where real slooow.[X(]
