Re: Controller battery life quantified
"Old Gazer"]1.4 per cell? Something doesn't sound right . 1.5 is full charge. They usually work down to about 1.0. Are you sure you didn't have a loose battery contact on one of the batteries? 140 minutes is only about 7 flights.
I agree with Old Gazer! I am troubleshooting an error with the 'radar function' not giving correct 'current heading' information and one of my steps is checking the RC battery voltage. I have been getting intermittent battery warning beeps from my RC, but no red flashing LED on the RC. Open circuit AA fresh battery voltage is 1.600 vdc +/- and my RC batteries open circuit voltage measured 1.338 vdc (x4 = 5.35 vdc), which should NOT have generated the battery warning beeps. According to the P2V manual, battery warning is issued at 4.0-4.3 vdc, or 1.00 to 1.08 vdc per cell.
1.4vdc per cell would be 5.6 vdc total and according to the manual, we should not be getting the battery warning signal!
I presently have 27 flights on my RC batteries, or about 540 minutes.
