Key Features:
- Automatic Functionality: Features an 'AUTO' function that sets feeding current during charging or discharging, preventing overcharging, especially for lithium batteries.
- Safety Mechanisms: Automatically disconnects circuits and alarms upon detecting malfunctions, ensuring maximum safety. All settings are user-configurable.
- Integrated Balance Charger: Employs an individual-cell-voltage balancer, eliminating the need for an external balancer for balance charging. Monitors and balances each cell during discharge, terminating the process if any cell voltage is abnormal.
- Versatile Lithium Battery Support: Adaptable to various lithium battery types including Li-ion, LiPo, and LiFe. Offers 'fast' charge for reduced duration and 'store' mode to optimize final voltage for long-term storage, protecting battery lifespan.
- Delta-Peak Sensitivity: Utilizes an automatic charge termination program based on Delta-peak voltage detection, ensuring charging stops when the battery's voltage exceeds a safe threshold.

5. Setup
5.1 Connecting Power
The IMAX B6AC charger can be powered by either AC (100-240V) or DC (11-18V) input.
- AC Power: Connect the provided AC input cable to the charger's AC input port (located on the side) and then plug it into a wall outlet.
- DC Power: Connect the Alligator Clip DC Input Cable to a 11-18V DC power source (e.g., a car battery or a regulated DC power supply). Ensure correct polarity.

5.2 Connecting Batteries
Connect your battery to the charger's output ports. For lithium batteries, always use the balance port in conjunction with the main charging port for safety and optimal performance.
- Main Output: Use the appropriate charging cable (e.g., XT60, JST, JR, Alligator Clip) to connect your battery's main power lead to the charger's output banana sockets.
- Balance Port (for Lithium Batteries): For LiPo, LiFe, and LiIon batteries, connect the battery's balance lead to the corresponding balance port on the charger (2S-6S).
