6. Operating Instructions
6.1. Basic Battery Charging
- Select Battery Type: From the main menu, navigate to the "Charge" or "Battery Type" option. Select the correct battery chemistry (e.g., LiPo, LiHV, LiFe, NiMh, Pb) using the scroll wheel.
- Set Cell Count: For Lithium-based batteries, set the correct cell count (e.g., 1S-6S for LiPo).
- Set Charge Current: Adjust the charge current (in Amperes) according to your battery's specifications. A common guideline is 1C (e.g., 5A for a 5000mAh battery).
- Connect Battery: Connect the main discharge lead of your battery to the output port (XT60 connector) and the balance lead to the balance port on the M7. Ensure secure connections and correct polarity.
- Start Charging: Navigate to the "Start" option and press the scroll wheel to begin the charging process. The display will show real-time charging data such as voltage, current, and capacity.
- Monitor Progress: Continuously monitor the charging process. The M7 will alert you upon completion or if an error occurs.
- Disconnect Battery: Once charging is complete, disconnect the balance lead first, then the main discharge lead.
6.2. Discharging and Storage
The M7 supports discharging and storage modes for various battery types. Select the appropriate mode from the main menu and follow the on-screen prompts to set parameters like discharge current and target voltage.
6.3. Signal Testing and Generation
The M7 can test PWM, PPM, and SBUS signals from receivers and generate signals for servos or ESCs. Connect the component to the signal port and select the desired function from the "Signal" menu.
6.4. Voltage and Internal Resistance Checker
Use the "Voltage" or "Internal Resistance" menu options to check the voltage of individual cells or the overall internal resistance of your battery pack. Connect the balance lead for accurate cell voltage readings.
7. Maintenance
- Cleaning: Regularly clean the exterior of the charger with a soft, dry cloth. Do not use solvents or abrasive cleaners. Ensure no dust or debris accumulates in the cooling fan or ports.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger does not power on. | No power input; incorrect input voltage; faulty power supply. | Ensure power supply is connected correctly and provides 7.0-28.0V DC. Test with a different power supply if available. |
| Charging error message displayed. | Incorrect battery type/cell count selected; poor battery connection; damaged battery. | Verify battery type and cell count settings. Check all connections (main and balance leads). Inspect battery for damage. |
| Charger gets excessively hot. | Poor ventilation; high ambient temperature; excessive charge/discharge current. | Ensure adequate ventilation around the charger. Reduce charge/discharge current. Operate in a cooler environment. |
| Display is unresponsive or frozen. | Temporary software glitch. | Disconnect power, wait a few seconds, then reconnect. If issue persists, check for firmware updates. |
| Inaccurate voltage readings. | Poor balance lead connection; damaged balance lead. | Ensure balance lead is fully and correctly inserted. Inspect balance lead for damage. |
