Hello Friends,
I'm using 8 AA's in my transmitter. The voltage is down to about 8.5 volts. When should I stop and put in new batteries?
Thanks

Fully discharged Alkaline are 0.8-1.0V, That means like almost dead. Get rid of them.

Depending on the radio, usually it lets you know when your batteries are too low.

Buy some rechargable AA's. Then when you hit 9V recharge them. I think 12V controlers cut out somewhere in the 7V range but don't quote me. Rechargables are best because you can keep them full after each outing. Plus they do pay for themselves after a few charges.

I just have to chime in on this one. I learned very quickly about having a good voltage in your transmitter. I set my 450 down, turned on my transmitter, then turned the heli on. My transmitter started to beep, and I looked down at it. The screen said "low battery" and then just went blank. All of a sudden my 450 started up on its own and got off about 3 feet by itself, I HAD NO TRANSMITTER ON AT THE TIME! So, the only thing I could do was toss my transmitter at the main rotors. Even though there was damage to the rotor blades, I saved my heli from flying away or even worse, hurting me or someone else.

Always check your batteries! I use rechargeable batteries now.
