I am just curious what your voltage per cell reads on your Lipo pack after a flight?

I asked this once and got no answer other than volts dont matter its what you put back thats important . But I can tell you my packs dont go below around 23 volts on a 6s pack after a 4 minute flight. So I guess I use a couple of volts when I fly. I hope I remembered this right

About 23 volts. I don't like to go much below this. 22.5 lowest! On 6 cell pack.

If you go below 3.7v per cell you have gone too far (22.2v for a 6s pack). It’s best to use the 80% recharge rule and time the flights instead of battery voltage.

3.75v/cell no load.

3.75 v/cell is a good place to stop (no load) but honestly the true answer changes as cell chemistry improves. the higher "C" the cell, the higher number you should stop. old 5C cells were 90% discharged at about 3.2 volts per cell unloaded, now its closer to 3.7 with the current 30 and 40C cells. How times have changed......

You should never use more than 80 percent of the total mah.
In other words, if you have a 3000 mah batt you should only use 2400 mah.

I set the timer to 5mins and 30 seconds starting from when I spool up the main rotor. I am using 6S 3000mAh 30C, and the end voltage for each cell never drops below 3.8v. I am running 85% flat curve.
