4.2 Battery Connection

Before connecting any battery, ensure it is compatible with the charger and in good physical condition.

1. Identify the main discharge lead and the balance lead of your battery.
2. Connect the main discharge lead of the battery to one of the main output ports (CH1 or CH2) on the front of the charger. Ensure correct polarity.
3. Connect the balance lead of the battery to the corresponding balance port next to the main output port. The balance plug should fit securely.
4. Repeat for the second channel if charging two batteries simultaneously.

5.2 Charging/Discharging Modes

After connecting a battery, the charger will automatically detect some battery parameters. You will then need to select the desired operation mode:

• Charge: Standard charging mode.
• Balance Charge: Charges and balances individual cell voltages for multi-cell batteries. Recommended for LiPo/Li-ion/LiFe/LiHv batteries.
• Discharge: Discharges the battery to a set voltage.
• Storage: Charges or discharges the battery to a specific voltage level suitable for long-term storage, preserving battery health.

5.3 Battery Type Selection

It is crucial to correctly select the battery type and cell count (for multi-cell batteries) in the charger's menu to prevent damage. The charger supports:

• LiFe/Lilon/LiPo/LiHv (1-6S)
• NiMH/Cd (1-16S)
• Pb (1-12S)

5.4 Dual Task and Parallel Task Functions

• Dual Task: Allows the charger to perform independent charge/discharge/storage tasks on two separate batteries simultaneously, each with its own parameters.
• Parallel Task: This function enables the charger to combine the power of both channels to output maximum power to a single battery. This requires a parallel charging board (not included) and careful attention to battery compatibility and safety.

5.5 DC Power Output (CH1)

Channel 1 (CH1) can function as a DC power supply. Refer to the on-screen menu for specific settings and output voltage/current adjustments when utilizing this feature.

5.6 USB Output

The 5V/2A USB output port on the side of the unit can be used to charge mobile phones or other compatible electronic devices.

6. Maintenance

Proper maintenance ensures the longevity and safe operation of your ISDT D2 Mark 2 charger.

• Cleaning: Disconnect the charger from all power sources and batteries before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use solvents or abrasive cleaners.
• Cooling System: The charger features a dual-fan cooling system. Ensure the fan vents on the rear panel are not obstructed during operation. Regularly check for dust accumulation and gently clean if necessary to maintain optimal airflow.
• Storage: Store the charger in a dry environment, away from direct sunlight and extreme temperatures. The recommended storage temperature is -20°C to 60°C (-4°F to 140°F).
