2. Safety Information
WARNING: Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
- Always wear appropriate personal protective equipment, including eye protection and gloves, when working with batteries.
- Ensure adequate ventilation during charging to prevent the buildup of explosive gases.
- Do not expose the charger to rain or wet conditions.
- Never attempt to charge a frozen or damaged battery.
- Ensure the charger is disconnected from the AC power outlet before making or breaking connections to the battery.
- Keep the charger and battery away from open flames, sparks, and heat sources.
- This charger is for charging lead-acid (SLA, AGM, GEL, Deep Cycle) and LiFePO4 batteries with Battery Management Systems (BMS) only. Do not use for other battery types.
3. Product Overview
3.1 Components and Controls
- LCD Display: Shows real-time voltage, amperage, and error codes.
- Indicator Light: Red for charging, Green for fully charged.
- Power Switch: ON/OFF switch for the unit.
- Level Volt Knob: Selects the charging voltage (12V, 24V, 36V, 48V, 60V, 72V) and 'H' mode for pulse repair/equalization.
- Ampere Control Knob: Adjusts the charging current (Low, Medium, High).
- Output Terminals: Positive (+) and Negative (-) connections for battery clamps.
- Overload Reset Button: Resets the charger in case of an overload.
- AC Input: Power cord connection (110V, 50/60Hz).
4. Setup and Connection
Follow these steps to safely connect your battery charger:
- Ensure the charger's power switch is in the OFF position.
- Connect the red (positive) battery clamp to the positive (+) terminal of the battery.
- Connect the black (negative) battery clamp to the negative (-) terminal of the battery.
- Plug the charger's AC power cord into a standard 110V, 50/60Hz electrical outlet.
- Select the appropriate voltage on the Level Volt Knob that matches your battery's voltage.
- Turn the charger's power switch to the ON position. The red indicator light will illuminate, and the LCD display will show the charging status.

5. Operating Instructions
5.1 Voltage Selection
The Level Volt Knob allows you to select the appropriate voltage for your battery pack. Ensure the selected voltage matches your battery's nominal voltage (e.g., 12V, 24V, 36V, 48V, 60V, 72V). If an incorrect voltage is selected, the charger may stop charging after a few seconds to protect your battery. To restart, adjust the knob to the correct voltage and cycle the power switch.
5.2 Amperage Control
Use the Ampere Control Knob to select the charging current: LOW, MEDIUM, or HIGH. A lower current provides a slower, more thorough charge, which is beneficial for battery health and desulfation. A higher current offers faster charging.
5.3 Pulse Repair (H Mode) and Desulfation
The 'H' position on the Level Volt Knob activates the pulse repair and desulfation mode. This mode applies high-voltage pulses to break up sulfate crystals that can build up on lead-acid battery plates, restoring lost battery performance and extending battery lifespan. This mode also functions as an equalizing charge, balancing individual cells within a battery pack.
5.4 Charging Process and Indicators
The charger utilizes a multi-stage charging process to optimize battery health and charging efficiency:
- Stage 1: Deep Discharge Charging Pulse Mode: For deeply discharged batteries.
- Stage 2: Constant Current Mode (CC): Current is constant, voltage slowly increases.
- Stage 3: Constant Voltage Mode (CV): Voltage is constant, current slowly reduces.
- Stage 4: Standby Voltage Mode: Current slowly reduces to zero, maintaining the battery.
The LCD Display shows real-time voltage and amperage. The Indicator Light will be red during charging and turn green when the battery is fully charged (current drops to 0 amps). The charger can be left connected indefinitely without harming the battery once fully charged.

6. Maintenance
- Cleaning: Disconnect the charger from power and battery. Wipe the casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Cable Care: Inspect battery cables and clamps for damage before each use. Replace if frayed or broken.
- Storage: Store the charger in a cool, dry place when not in use. Keep out of reach of children.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on / No display | No AC power; Loose connections; Blown fuse. | Check AC outlet and power cord. Ensure battery clamps are securely connected. Check and replace fuse if necessary. |
| Charger stops after a few seconds (shows "OFF" or error) | Incorrect voltage selected; Battery fault (e.g., short circuit, reverse polarity). | Verify the Level Volt Knob matches battery voltage. Check battery for faults. Disconnect and reconnect. |
| Battery not charging or charging slowly | Low amperage setting; Severely discharged battery; Battery sulfation. | Increase Ampere Control Knob setting. For deeply discharged batteries, use 'H' mode for pulse repair. Allow more time for charging. |
| Overload indicator / Charger shuts off | Overcurrent; Internal fault. | Press the Overload Reset Button. Reduce amperage setting. If problem persists, contact support. |
