5. Setup and First Use

5.1 Power Connection

1. Connect the provided AC input cable to the AC input port on the side of the charger.
2. Plug the other end of the AC cable into a suitable wall outlet (AC100-240V).
3. Alternatively, for DC input (DC7-30V), connect a compatible DC power source to the DC input port.
4. The charger will power on, and the display will illuminate.

5.2 Connecting Batteries

1. Identify the main discharge connector and the balance connector of your battery.
2. Connect the battery's main discharge connector to either the CHA or CHB port on the charger. Use the appropriate adapter if necessary (e.g., XT60-T, XT60-EC3, XT60-EC5).
3. Connect the battery's balance connector to the corresponding balance port (2S-6S) next to the main charging port. Ensure the balance plug is inserted correctly.
4. For G-Tech smart batteries, the charger will automatically recognize the battery type and parameters upon connection.
5. For non-G-Tech batteries, you will need to manually set the battery type, cell count, and charging current via the charger's interface.

6. G-Tech Smart Features

The IMARS D300 charger is equipped with G-Tech smart technology, simplifying the charging process and enhancing safety, especially when used with Gens Ace G-Tech smart batteries.
