Hobbico Voltwatch w/6.0v battery issue?
I recently switched out 2 of my old 4.8 volt 1500mah receiver batteries with 2 new 6.0v 2000mah NiMH batteries. I have a hobbico voltwatch in each plane and it's giving me inconsistent readings. As soon as I turn the airplane on, most of the green "safe" lights light up. When I move a servo it get worse and the yellow "caution" light lights up. I switch the voltwatch over to 4.8v setting and it fine. I know that's not right I want a accurate reading for the 6.0v.
Each plane has the same receiver (AR6200), same batteries, and servos (DS821). The battery charge in the first battery was 6.23v, 1950mah and the second battery was 6.41v, 1965mah, so I know I have properly charged batteries. What seems to be the problem?
Has any used the Loganville Hobbies Spy Cell?
Thanks
