External charging
The HV batteries should be charged under supervision or where the risk of a battery fire will
cause minimum damage to the surroundings.
1. Remove the HV batteries from the fuselage.
2. Connect the charger plug to the batteries.
3. Turn charger ON. If the toggle switch is operated while the charger is switched on, the
winter charging mode is activated.

Once the charger is connected 12 V power is supplied to the battery manager. The battery
manager starts the charging process by activating the HV relays.
When batteries are fully charged the battery manager switches off the charging process.
If a single battery is charged outside the fuselage, the terminal plug must be inserted in the
connector of Cable B of the battery charger, as illustrated in Figure 10-8.
