Yes, I understand about them being just like other lipos. What I am concerned about is whether the radio still operates safely at 7 volts?

The stock battery had a nominal voltage of 7.2v so I don't think 7.0v would be a problem. I downloaded the manual and I can't seem to find anything about the lowest allowable voltage for the transmitter.

However, look at page 69 in the manual...the default cutoff voltage in the Aurora 9x for lipos is 6.0v. They allow you to change that from 6.0 to 6.5 as most lipo manufacturers don't recommend discharging to 3.0v/cell for very long. If the internal settings allow a cutoff of 6.0v then I'd have to imagine the transmitter is still functional at that voltage.

Still, I'd recharged before 7.0v/cell just to be on the safe side...although apparently 6.0v is the default setting.

According to the manual (pg 21), you can adjust battery voltage alarms with the HPP-22.

Thanks!

Since I don't like going below 3.75, I will use that as the lowest voltage.

6.0v is the setting for LiPo, wouldn't advise letting it below 6.5 volts. Keep an eye on it and pull the pack out and recharge it when it gets to ~7.5v ish. With a 2600mah 2s lipo, you're going to last quite a long time. One of our team pilots uses a 2s 2600 lipo and he claims it lasts him weeks before recharging and he's always out flying.

I finally got some max altitude readings on radio. It held them in the little boxed in portion. My glider was at 396 feet at one point of the flight but I think it stopped. It seemed liked I soared up a little higher after that reading.
