6. Safety Instructions

Please read and understand these safety instructions before using the charger:

Indoor Use Only: This charger is designed for indoor use. Do not expose it to rain or moisture.
Ventilation: Ensure adequate ventilation during charging to prevent overheating.
Explosive Gases: Batteries can produce explosive gases. Keep away from flames and sparks.
Disconnect Power: Always disconnect the power supply before making or breaking connections to the battery.
Correct Battery Type: Only charge batteries of the specified types (LiPo, LiFe, LiHV, NiMH) and cell counts. Charging incorrect battery types or cell counts can lead to fire or explosion.
Supervision: Never leave the charger unattended while in use.
Damage: Do not use the charger if it or the battery appears damaged.
Children: Keep out of reach of children.

7. Setup

Placement: Place the charger on a stable, non-flammable surface, away from flammable materials. Ensure good ventilation.
Power Connection: Connect the AC power cord to the charger's AC input port, then plug the other end into a suitable 100-240V AC wall outlet. The charger will power on.
Battery Connection: Connect your battery to the appropriate charging port on the charger. For LiPo/LiFe/LiHV batteries, connect both the main discharge plug and the balance plug. For NiMH batteries, only the main discharge plug is needed.

8. Operating Instructions

Follow these steps to charge your batteries:

Power On: Connect the charger to AC power. The Charge Status LED will blink green, indicating it's ready.
Select Battery Type: Press the 'BATT TYPE' button repeatedly to cycle through LiPo, LiFe, LiHV, and NiMH. The corresponding LED indicator for the selected battery type will illuminate.
Select Charge Current: Use the 'Current Switch' to select the desired charge current (1A, 2A, 3A, or 4A). Choose a current appropriate for your battery's capacity (e.g., 1C rate).
Connect Battery: Connect your battery to the charger. For LiPo/LiFe/LiHV, ensure both the main discharge plug and the balance plug are securely connected. For NiMH, only the main discharge plug is needed.
Start Charging: Once the battery type and current are selected, and the battery is connected, the charger will automatically begin charging. The Charge Status LED will glow constant red (CC mode) then constant orange (CV mode) for LiPo/LiFe/LiHV, or constant red for NiMH. The Cell Status LED will glow constant red.
Monitor Charging: Observe the LED indicators. When the Charge Status LED glows constant green, the charging process is complete.
Disconnect Battery: Once charging is complete, first disconnect the battery from the charger, then unplug the charger from the AC power outlet.

9. Maintenance

Cleaning: Use a soft, dry cloth to clean the charger. Do not use solvents or abrasive cleaners.
