Oh man! I was logging data on a few packs, and forgot to reset the timer on my radio after a pack.

As a result I ran for 8 minutes, instead of my normal 6 on my t-rex450 with an FP 2170 25C battery.

According to the logger, minimum voltage thourgh the run was 10.41, but milliamps out was 1849.

According to the charger the cells were at 3.5, 3.6, and 3.7(not under load, after cooling off for 45-60 minutes).

While I realize the minimum voltage of 10.xx could mean one batery at 2, and two at 4 volts, I suspect nothign ever went below 3V, the spred just isnt that wide on the cells. I was just practicing, hovering, and some simple forward flight, in my backyard.

I don't indend to ever do this again, but is the over 80% MAh discharge mean I just wasted a pack, or is the voltage the better of the two indicators... I have four of these packs, all fairly new, they are sooo good... I really don't want to loose one.

I have done that myself... twice. One time the pack did not come back. You sound like you fine.

The pack did not puff, and it did charge ok, hopefully its cool, I'll just keep the datalogger on my packs, to see if its performance degrades
