What value should I use for LOW_VOLT parameter for a 3S battery?

The default value it's 9.6, but that seems way too low.

Every time I try to search "lipo low voltage" I find hundreds of contradictory articles. What do you guys use?

Thanks!

Set it to 3.5v per cell (10.5v total), as per Randy's suggestion.

Mine is hardwired to go off at 3.4, but I've had a (expensive!) voltage-drop Loss of Control event because of it. I'm happy to trade 3-4 minutes of flight time and range anxiety for less stressful landings.

A new customisable alarm is onroute.

My understanding is that you can damage the lipo cell if it drops below 3 volts. My alarm goes off at around 3.5 volts so I think if you stay between 3.2 - 3.5 you should be fine.
