Charging while turned off
We recommend recharging your Flytec Balloon 4 between flights, once the battery charge has dropped below 25%.
Turn your vario off for this.
Once you connect the charger, the vario will turn itself on in charging mode, indicated by the running battery charge
meter in the status bar, and the battery charge status for the two battery pairs.
Charging while running
You can extend the vario's battery lifetime by connecting a charger or external battery ("power bank") to the Flytec
Balloon 4's USB connector once the vario has been switched on. While an external power source is connected, the
Flytec Balloon 4 will draw its power from that source to run, and to charge its batteries. Once the external power
source is depleted, the internal batteries will be used up.
The charging mode is indicated by the running battery charge meter in the status bar. Additionally, by flipping
through the flight pages at the bottom of the screen, you will find an additional page 7, with the charge status for the
two battery pairs.
Low battery alert
If the battery charge approaches 10%, the Flytec Balloon 4 emits an acoustic alert, and displays a warning message.
This is repeated when turning off the vario, as a reminder to charge the batteries before the next flight.
Replacing batteries
If you forgot to charge the batteries, you can replace them temporarily with four regular Alkaline AA batteries.
Remember to switch the battery type to ensure the battery charge indicator is correct.
Rechargeable batteries will loose capacity with time and use. If you find the operation time on a full charge to
decrease below 15 hours, it's probably time to replace the batteries with a new set.
