Operating Instructions

Charging the Battery

Use only the VATOSO 29.4V 2A charger provided with your battery. Charging can be done with the battery removed from the wheelchair or while installed, depending on your wheelchair's design.

1. Ensure the battery is connected to the charger via the Anderson connector.
2. Plug the charger into a standard 110V-220V AC power outlet.
3. The charger will indicate charging status (e.g., an LED light changing color).
4. Charge until the charger indicates a full charge. The charge cut-off voltage is 29.4V.
5. Once fully charged, disconnect the charger from the power outlet, then disconnect it from the battery.

Important: Do not overcharge the battery. The built-in BMS will help prevent this, but it is good practice to disconnect once fully charged. Do not charge in wet conditions.
