i put an 8 cell turbin pac in so if i dropped a cell the turbine would not "see " low bat and shut down ( i told a turbine manufacturer over a year ago that i was doing it and now its standard equiptment with them)...........i always use a i4c volt meter on it ( and watch it on power ups ).....i also use 2 switches and 2 rx bats with one volt meter....i switch 1 on to read ( tugging on the elevator gimble)...turn it off and then the other....then with both on .....a binding or over traveling servo will show up on the meter.........why do i do it???to know my batteries and servos and to recognize when they are getting sick
