Setup
- Placement: Place the charger on a stable, flat surface in a well-ventilated area, away from direct sunlight, heat sources, and moisture.
- Connect to Battery:
- Connect the positive (+) red terminal of the DC power cable to the positive (+) terminal of your LiFePO4 battery.
- Connect the negative (-) black terminal of the DC power cable to the negative (-) terminal of your LiFePO4 battery.
- Ensure the connections are secure and polarity is correct.
- Connect to AC Power: Plug the AC power cord into the charger's AC input port, then plug the other end into a standard, grounded wall outlet (100-240V AC, 50/60Hz).

Operating Instructions
Charging Process:
Once connected, the charger will automatically begin the charging process. It utilizes an intelligent 3-phase charging algorithm:
- Phase 1: Pre-charge (T1) - Initial low-current charge for deeply discharged batteries.
- Phase 2: Constant Current (CC) (T2) - Charges the battery at a constant high current until voltage reaches a set level.
- Phase 3: Constant Voltage (CV) (T3) - Charges the battery at a constant voltage, with current gradually decreasing until the battery is fully charged.

0V Activation Function:
The charger can reactivate dormant LiFePO4 batteries that have entered a low-voltage protection state (0V). It will attempt to restore the battery to its normal operating voltage. This function is compatible with most LiFePO4 batteries on the market.

LED Indicator Status:
The LED indicator provides visual feedback on the charging status and diagnostic information:
| LED Status | Meaning |
|---|---|
| Red (Solid) | Battery is charging. |
| Green (Solid) | Battery is fully charged. |
| Green (Flashing) | Charger is in standby mode. |
| Red (Flashing) | Charger fault or protection activated. |

Maintenance
Proper maintenance ensures the longevity and optimal performance of your charger:
- Cleaning: Disconnect the charger from both AC power and the battery before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Storage: Store the charger in a cool, dry place when not in use. Ensure cables are neatly coiled and not kinked.
- Inspection: Periodically inspect the charger, cables, and connectors for any signs of damage, wear, or corrosion. Replace damaged components immediately.
- Ventilation: Ensure the cooling fan and ventilation openings are free from dust and obstructions.
Troubleshooting
If you encounter issues with your charger, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on (no LED) | No AC power; faulty power cord; charger malfunction. | Check AC power connection and outlet. Ensure power cord is securely plugged in. Try a different outlet. If problem persists, contact support. |
| Red LED flashing | Output short-circuit; reverse polarity; overcurrent; over/undervoltage; overheating. | Disconnect from battery and AC power. Check battery connections for correct polarity and secure fit. Inspect cables for damage. Allow charger to cool if hot. Reconnect carefully. If fault persists, contact support. |
| Battery not charging (Green LED flashing) | Charger in standby; battery already full; poor connection. | Ensure battery is not already fully charged. Check all connections to the battery and AC outlet. If the battery is deeply discharged (0V), the charger should attempt activation. |
| Slow charging | Battery capacity is very high; external factors (temperature). | Charging time for a 100Ah 12V battery is approximately 5 hours. Larger batteries will take longer. Ensure charger is in a well-ventilated area. |
