The main charger unit is black with a label indicating "Li-ion Charger," "MODEL: HRK-125E-13S," "INPUT: AC100V~240V 50/60Hz," and "OUTPUT: DC 54.6V --- 2A." It also displays safety warnings like "CAUTION! HAZARDOUS AREA INDOOR USE ONLY Do Not Remove This Cover Trained Service Personal Only." The charger has a power input cable on one side and a barrel connector output cable on the other. Both cables are neatly coiled beside the charger.
3. Setup
Follow these steps to prepare your charger for use:
- Verify Compatibility: Confirm that your device's battery is a 48V Lithium-ion type and requires a 54.6V 2A charger with a barrel connector.
- Inspect Connector: Carefully check the shape and size of your device's charging port to ensure it matches the DC 5.5mm*2.1mm barrel connector of this charger.
Image Description: A diagram illustrating the dimensions of the DC 5.5mm*2.1mm barrel connector. It shows a close-up of the male barrel connector with measurements indicating an outer diameter of 5.5mm and an inner pin diameter of 2.1mm. This visual aid helps users confirm compatibility with their device's charging port.
- Connect to Device: Insert the barrel connector firmly into your device's charging port.
- Connect to Power: Plug the AC power cord into a standard 100V-240V AC wall outlet.
4. Operating Instructions
Once connected, the charger will automatically begin charging your 48V Lithium-ion battery. The LED indicator on the charger provides status updates:
- RED LED: Indicates that charging is in progress.
- GREEN LED: Indicates that the battery is fully charged or the charger is disconnected from the battery.
Image Description: Two side-by-side images of the HERISKEER charger. The left image shows the charger with a red LED illuminated, indicating "RED Light - Charging." The right image shows the same charger with a green LED illuminated, indicating "Green Light - Full charge or disconnected." This visually explains the charging status indicators.
When the LED turns green, the charging process is complete. Disconnect the charger from the wall outlet first, then from your device.

7. Maintenance
To ensure the longevity and proper functioning of your charger:
- Cleaning: Wipe the charger with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Storage: Store the charger in a cool, dry place when not in use. Avoid extreme temperatures and direct sunlight.
- Cable Care: Do not bend or crimp the cables excessively. Avoid placing heavy objects on the cables.
- Impact Avoidance: While designed with robust components, avoid dropping the charger, especially on hard surfaces like concrete or asphalt, as this can damage internal electronics.
8. Troubleshooting
If you encounter issues with your charger, refer to the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger LED does not light up. | No power from outlet; Charger not properly plugged in; Faulty outlet; Damaged charger. | Check wall outlet with another device; Ensure all connections are secure; Try a different outlet; If still no light, the charger may be faulty. |
| LED is green but battery is not fully charged. | Charger disconnected from battery; Battery issue; Incompatible battery. | Ensure the barrel connector is securely inserted into the device; Verify battery health; Confirm battery is 48V Lithium-ion. |
| LED remains red for an extended period. | Battery deeply discharged; High capacity battery; Charger malfunction. | Allow more time for charging; If charging time is excessively long or the charger feels unusually hot, disconnect and contact support. |
| Charger or device gets excessively hot. | Overload; Poor ventilation; Internal fault. | Immediately disconnect the charger from both the wall and the device. Ensure adequate ventilation. Do not use if overheating persists. |
| Device not charging or showing error. | Incorrect voltage/connector; Device battery management system (BMS) issue; Charger fault. | Re-verify charger compatibility (48V Li-ion, 5.5x2.1mm barrel connector). Consult your device's manual for battery or charging port issues. |
If troubleshooting steps do not resolve the issue, discontinue use and contact HERISKEER customer support.
