hitec815bb amh eater
 

i am using a 2000amh pack nimh to power an 815bb servo on a soling 1 meter sail boat. iam gettingless than 2 hrs run before my sail servo wont move. ichecked voltage,and read 6.36volts.is something wrong with theservo ?can iadd 0ne more 1.2v nimh battery to thepack? thanks jim

an extra cell added in series will give you more voltage, but not more runtime.

With small servos in on-road cars we get about 11 mah per minute draw from a receiver pack, I'd expect that to be higher with your servo - maybe 15 mah or more. At this rate, you'd lose 1800 mah in 120 minutes (2 hrs) which sounds about right to drain a 2000 mah pack
