Default SD-10G Issue With TX Battery Voltage

The LCD Display overview on my radio shows a fluctuating voltage read. Never happened in the past as far as I recall. Specifically, after a proper fresh charge, the LCD display reads 8.1v and a second later, reads 7.2 v and then it bounces up to 8.1v or 7.6v or 7.4v. After two -three flights, it dips lower which is to be expected, but fluctuates as before to levels I'm uncomfortable with.

Then I stop flying.

At first, I thought it was the original battery, so I changed it to a low time 6 cell 2000mAh Eneloop .

Same voltage irregularities.

The radio went back to Airtronics late last year for the recall/upgrade of the circuit board.

I had the same problem after RF upgrade. Removed pack & tested with a load on it & battery made a big drop. It had a bad cell. Replaced with a 2000mah Eneloop NMH & it's ROCK STEADY.

I have noticed this with mine also. anyone figure out the cause? I cycled the batt a few times and it seemed to be a little better. Think i am just going to go 2 cell lipo.
