Which voltage for 3s lipo alarm?

[matthew2456]

On the ground I have approx 3.7v per cell at the 20% level, what is this likely to equate to under load in the air?

I think I am correct in saying that LiPos don't really like to go below 3.2 volts per cell in flight.

It's sort of like asking "How long is a piece of string?" I'm afraid as the demand on the batteries is different in different helis and different conditions. I'd say Lee is about right at 3.2v certainly no lower.

This is why I just use a timer and see what I put back in at the end and adjust the timer accordingly. I always err on the side of a shorter flight as well

"How long is a piece of string?"

Half its length then times it by two = length of string


Sorry hehehehhehe.....

Mine is set at 3.4v and that takes me down to almost exactly 20% with most of the lipo's I have tried.
