1. Introduction
Thank you for choosing the DIGISHUO 14.6V 10A LiFePO4 Battery Charger. This charger is specifically designed for charging and maintaining 12V (12.8V) LiFePO4 lithium-ion batteries. It features a 2-stage constant current/constant voltage (CC/CV) charge algorithm to optimize charging efficiency and battery lifespan. Please read this manual thoroughly before use to ensure safe and effective operation.
2. Safety Information
WARNING: Risk of Electric Shock. Do not open the charger casing.
- This charger is designed exclusively for 12V (12.8V) LiFePO4 batteries. Do not use it with other battery types (e.g., lead-acid, Ni-Cd, Ni-MH) as this may cause damage to the battery or charger, or result in injury.
- Ensure the charger is connected to a power outlet with the correct voltage (100-220V AC).
- Always connect the charger to the battery terminals correctly: red clip to positive (+), black clip to negative (-). Reverse connection can cause damage.
- Operate the charger in a well-ventilated area. Do not cover the charger during operation.
- Keep the charger away from water, moisture, and flammable materials.

6. Operating Instructions
Charging Process:
- Once properly connected (as per Section 5), the charger will automatically begin the charging process.
- The LED indicator on the charger will illuminate RED, indicating that the battery is currently charging.
- The charger employs a 2-stage Constant Current/Constant Voltage (CC/CV) algorithm for efficient and safe charging.
- When the battery is fully charged, the LED indicator will turn GREEN. The charger will automatically stop charging to prevent overcharging.
0V Charging Function (Battery Reactivation):
This charger supports a 0V charging function, which can help reactivate or repair long-unused LiFePO4 batteries that have entered a deep discharge state. When connected to such a battery, the charger will attempt to bring its voltage up to a level where normal charging can commence. This process may take longer than regular charging.
7. Maintenance
- Keep the charger clean and dry. Wipe the exterior with a soft, dry cloth. Do not use solvents or abrasive cleaners.
- Regularly inspect the cables and alligator clips for any signs of damage, fraying, or corrosion. Replace if necessary.
- Ensure the cooling fan is not obstructed to allow for proper heat dissipation.
- Store the charger in a cool, dry place when not in use.
- If the fuse blows, replace it with a fuse of the same type and rating (a backup fuse is included in the package).
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger LED does not light up. | No power from outlet; Loose connection; Blown fuse. | Check power outlet; Ensure all connections are secure; Check and replace fuse if necessary. |
| LED remains RED for an extended period. | Battery is deeply discharged or high capacity; Battery fault. | Allow more time for charging, especially for large or deeply discharged batteries. If it never turns green, the battery may be faulty. |
| LED immediately turns GREEN after connecting. | Battery is already fully charged; Poor connection. | This is normal if the battery is full. If not, check connections for proper contact. |
| Charger gets hot during operation. | Normal operation; Obstructed cooling fan. | Some heat is normal. Ensure the cooling fan is not blocked and the charger is in a well-ventilated area. If excessively hot, disconnect and contact support. |
