Setup

1. Power Connection:
   • For AC input, connect the provided AC power cable to the charger's AC input port and then to a standard wall outlet (AC 100-240V).
   • For DC input, connect a DC power source (7.0-28.0V) to the charger's DC input port. Ensure correct polarity.
2. Initial Power On: Once connected to power, the charger will automatically power on and display the main menu on the IPS LCD screen.
3. Navigation: Use the scroll wheel and button on the right side of the charger to navigate through menus and select options.

Operating Instructions

1. Battery Charging

1. Connect Battery: Connect your battery's main discharge lead to one of the XT60 output ports. For multi-cell batteries, also connect the balance lead to the appropriate balance port (2-6S).
2. Select Battery Type: From the main menu, navigate to the "Charger" function. Select the correct battery type (LiPo, LiHV, LiFe, Lion, LTO, NiMh, Pb) and cell count (e.g., 3S, 6S).
3. Set Charging Parameters: Adjust the charging current (up to 15A) and mode (e.g., Balance Charge, Fast Charge, Storage Charge) as required for your battery. The maximum charging power is 300W.
4. Start Charging: Confirm settings and start the charging process. The screen will display real-time charging status, including total voltage, current, charged capacity, and individual cell voltages.

2. Battery Discharging

The M7AC supports discharging batteries with a power of up to 300W in Recycle mode or 15W in Normal mode.

1. Connect Battery: Connect the battery to the XT60 output and balance port.
2. Select Discharge Function: Navigate to the "Discharge" function in the menu.
3. Set Parameters: Set the discharge current and target voltage.
4. Start Discharging: Initiate the discharge process. Monitor the battery temperature and voltage during discharge.

3. Power Supply Function

The M7AC can act as a regulated DC power supply (1.0-28.0V, 0.5-15A).

1. Access Power Supply Mode: Select the "Power Supply" option from the main menu.
2. Set Output Voltage and Current: Adjust the desired output voltage and current limit using the scroll wheel.
3. Connect Device: Connect your device requiring power to the XT60 output port.
4. Activate Output: Enable the power supply output.

4. Multimeter Function

Measure voltage and internal resistance of batteries.

• Voltage Measurement: Connect the battery to the balance port to measure individual cell voltages (1.0-5.0V per cell, 1-6S).
• Internal Resistance Measurement: The charger can measure internal resistance from 0.1 mR to 99mR for 1-6S batteries.

5. Signal Source / Tester

The M7AC can generate and test various signals.

• PWM Output: Generate PWM signals (500-2500us @ 20-1000Hz).
• PPM Output: Generate PPM signals (880-2200us * 8CH @ 20-50Hz).
• SBUS Output: Generate SBUS signals (880-2200us * 16CH @ 20-100Hz).

6. USB-A Output

The USB-A port provides 5.0V at 2.1A, suitable for charging mobile devices or powering small electronics.
