Checking Battery Voltage
Gannet supplies a battery checker with the Gannet II / II MAX. The battery checker
will check the voltage of the battery and the voltage of each cell in the battery.
Plug the balancer cable of the battery into the battery tester. The tester will BEEP,
and then show the total voltage of the battery, followed by the voltage of each
cell.
A fully charged LiHV 4s battery is 17.4V and each cell should be 4.35v. The cells
may vary up or down by 0.02v (range 4.18v to 4.22v) Do not use if there is a
variance greater than 0.2v between the cells.
A fully charged LiPo 4s battery is 16.8V and each cell should be 4.20v. The cells
may vary up or down by 0.02v (range 4.18v to 4.20v) Do not use if there is a
variance greater than 0.2v between the cells.
Always fly will a fully charged battery. Do not fly with a partially discharged battery
as you do not know how much energy or flight time is left in the battery.
Never fly with a battery that has a voltage reading less than 15.5 volts. This means
the battery is low and the safety margin is reduced.
