I have a old kopropo helios. I want to convert its power source to 3s lipo. The problem I have is Helios has a low voltage alarm set at 9 v which is too low for 3s lipo. I think the minimum for 3s is 9.9v. So I need a some kind of cut off circuit between my transmitter and 3s lipo. Can someone direct me to a place that sells lipo cutoff circuit?
Thanks
Eddy
