Status: offline 		I am finishing up my 27% Cap 232 and I have a battery question for you guys. I will be running all Digital Hitec Servos. Two Hitec 5625 on the ailerons, Two Hitec 5645 on the elevators and One hitec 5735 on the rudder(Kind of a over kill but that is what I had.) One Futaba 3004 on the Throttle. For batteries I will be running Two 1800 mah NIMH 6 volt double AA style batteries for a total of 3600 mah (Each battery hooked up to a separate switch and different channel on the receiver) My question is will this be enough for my digital servos as far as Capacity. These will be my first 6 volt batteries and also, my first NIMH batteries. I am looking for all the input I can get. I don't want to take any chances with this plane. Thanks

Status: offline 		Thanks for the info so far guys. I have one more question. When I am flying my 4.8 volt Ni-Cads I check the volts with my volt meter after charging and they are about 5.6-5.7 volts. I usually re-charge them when they hit 4.8-4.9 volts. I just finished charging my 6.0 volt NIMH and they checked out at 6.9 volts. My question is how low should I let them get before I re-charge them. Thanks

re-charge a 6 volt pack when it gets down to 6 volts.

I usually wait until it drops below 6 volts by just a little (5.98 for example). The reason is that they usually stay at 6 volts for a while.

But do what you feel comfortable with. If you like to recharge when it gets close to 6 volts (6.1 etc) that's your call. But most people here will tell you to recharge when you get to 6 volts (4.8 volts on a 4.8v pack).

Unless you are applying a 1 amp load, you are looking for trouble.
