3.2 Initial Battery Charging
Before first use, fully charge both lithium batteries. The wheelchair features two charging methods:
- Direct Battery Charging: Remove the battery packs from the wheelchair and connect them to the external charger.
- On-Wheelchair Charging: Plug the charger directly into the charging port on the wheelchair.
A full charge typically takes approximately 6 hours. The charging indicator lights will show the charging status.
