I have always used the hobbico volt watch's
on all my planes, but I didnt think it looked good
on my h9 p51 so i didnt mount one on it.
I have a Digital Multimeter for checking Voltage
a new 1400 mah battery pack shows about 5.45 - 5.65 volts
on a fresh 24 hour charge
and after several flights (3 - 5) 10-15 minute flights
it shows 4.97 volts
I know the packs are 4.8 volts what is the minimum
voltage everyone usally says not enough for another flight?

Thanks
