Hopefully the Rx dual battery telemetry is more accurate on this unit. I am always getting falsely low batteries reading whenever running it through a battery back up system.... It is always 2 tenths low. Also Futaba....if you are listening.... can you take the voltage reading out to the hundredths. 6.6 doesn't tell me if it is 6.61 or 6.69 which is a huge difference in residual capacity for an A123 battery. Thanks!
