DX7 Battery voltage
 
What should the transmitter battery voltage read on a full charge? Is the charge bar suppose to be full? I had mine on charge for 2 days and the bar is at 3/4 reading 11.1V. This doesnt seem right.

It is rare for it to show full with the stock battery, my 9303 do the same thing

If you read the instruction, it takes 30 + hours to charge the first time

you can plug in that charger and leave it on a week - it will harm nothing -
the charger is below the 1/10 level typical for these cellas as slow charge -
I use nothing but the little charger which came with the DX7-- left on now for overnite or a day or so I see 11.5 v surface level
the friggn radio will fly 8 hours on a charge so the charge setup -to me is perfect - charge whenever for however long - you won't harm the cells.
I hope my new JRx9303 has same cells and charger -

mine shows 11.5 - 11.4 just after charging over night, i think my charger is 110ma.

after 5 sessions of 12 minutes in the air today its down to 10.5, so thats 1 hour flight, plus pit and taxi time

G'day Mate,
As Dick said you have a looong way to go, I get about 12 hours out of a charge, from the DX7.
Remember the battery has a nominal voltage of 9.6, is flat at 8.8 volts, stop flying at 9 volts.
The DX7 uses about 108 Mah. That takes a long time to flatten a 1500 Mah battery.
