5. Setup

5.1. Connecting Power

1. AC Power (Household Outlet): Connect the supplied AC power cord to the AC input port on the side of the charger. Plug the other end into a suitable wall outlet (100-240V AC).
2. DC Power (External Power Supply/Battery): Connect a DC power source (11-18V DC) to the DC input ports on the side of the charger. Ensure correct polarity (+ to + and - to -).

5.2. Connecting Batteries

1. Identify the correct main charging cable for your battery (e.g., T-plug, XT60).
2. Connect the main charging cable to either Channel 1 (CH1) or Channel 2 (CH2) output port on the front of the charger.
3. For Lithium batteries (LiPo, LiFe, Lilon, LiHV), connect the battery's balance lead to the corresponding balance port on the balance board, then connect the balance board to the charger's balance port for the selected channel. This is crucial for safe and balanced charging.
4. Connect the main charging cable to your battery.

6. Operating Instructions

6.1. Powering On and Main Interface

Once connected to power, the charger will power on automatically (or use the power switch if available). The 3.2-inch color touch screen will display the main interface, showing options for different battery types and functions.
