Charging Instructions
- Turn off the connected equipment before charging when practical.
- Confirm that the charger is compatible with the HL2454B battery.
- Connect the charger's DC output connector to the dedicated battery charging port.
- Connect the charger to a suitable 100–240V AC power outlet.
- Allow the charger to complete its charging cycle according to the charger's status indicators.
- Disconnect the charger after charging is complete when appropriate for your application.
Charging Safety: Never charge the battery through its power output terminals. Do not use a regular laptop AC adapter or a charger designed for lead-acid batteries. A suitable lithium-ion charger must control charging voltage and current. Do not charge outside the specified 0°C–45°C temperature range.
The battery's internal protection circuit provides additional safety functions but is not a substitute for a properly matched battery charger.
Optional Battery Safety Guard Bag
For additional protection during transportation, charging, or storage, consider the BiXPower SH54 Battery Safety Guard Bag.
The optional bag uses silicone-coated fiberglass fabric designed for heat resistance and water resistance. It may help provide an additional protective barrier but cannot eliminate the risk of battery fire, thermal runaway, or other battery hazards.
Important: Follow the bag manufacturer's instructions, maintain adequate ventilation, and never obstruct charger cooling vents. The safety bag is optional and sold separately.
Applications: Power Compatible 24V Equipment
The HL2454B can provide DC power directly to compatible 24V equipment, including selected motors, lighting systems, electronics, and other DC-powered devices.
The battery's output voltage varies from approximately 29.4V when fully charged to approximately 21V near its discharge cutoff. Connected equipment must be compatible with this entire operating voltage range.

Check compatibility: Do not connect equipment that requires a constant 24V input unless it can tolerate the battery's full voltage range or a suitable DC-to-DC converter is used. For application planning, use a conservative continuous load limit of 1000W until the exact operating rating has been confirmed.
Use with a DC-to-DC Converter
A compatible DC-to-DC converter can transform the battery's varying output voltage into a different constant output voltage required by your equipment.
For example, an appropriate converter can provide constant voltage to equipment that requires a specific DC input. Confirm that the converter accepts the entire battery voltage range and supports the device's power requirements.
DC-to-DC converter is optional and not included. View BiXPower DC-to-DC Converter.
Use with a DC-to-AC Power Inverter
Connect the battery to a compatible 24V DC-to-AC inverter to supply AC power for selected equipment where utility power is unavailable.
A suitable inverter converts the battery's DC power into AC power, such as 110V/120V AC, depending on the inverter model.
Choose an inverter with an input voltage range compatible with the HL2454B, and account for inverter efficiency, continuous load, and startup surge current. Some appliances require substantially more power during startup than during normal operation.
DC-to-AC inverter is optional and not included. View Compatible Inverter Option.
Replace Two 12V Lead-Acid Batteries in Suitable 24V Systems
In some applications, one HL2454B battery may replace a 24V lead-acid battery system consisting of two 12V batteries connected in series.
Potential applications include compatible mobility scooters, electric scooters, powered carts, and other 24V equipment. However, this is not a universal drop-in replacement.
Before Replacing Lead-Acid Batteries
- Confirm that the equipment supports the HL2454B output voltage range of 21V–29.4V.
- Verify operating current, motor startup current, and peak power requirements.
- Check battery compartment dimensions, mounting requirements, terminal connections, and wiring.
- Confirm that the equipment does not require a specific lead-acid battery charging or battery monitoring system.
- Use the compatible HL2454B lithium-ion charger rather than the original lead-acid charger.
- Do not connect this battery directly in series or parallel with other batteries.
Some scooters and mobility equipment use 24V lead-acid battery systems, but compatibility with specific makes and models has not been verified by BiXPower. Please confirm electrical and mechanical requirements before purchasing or modifying your equipment. For mobility equipment, consult a qualified technician or the equipment manufacturer before conversion.

Actual performance depends on battery chemistry, system design, discharge rate, operating temperature, and charging practices.
Estimated Battery Runtime
The HL2454B stores approximately 1774Wh of rated energy. Actual runtime depends on device power consumption, battery condition, temperature, conversion losses, and operating conditions.
| Average Device Load | Ideal Calculation | Illustrative Runtime at 85% Usable Energy |
|---|
| 50W | 35.5 hours | 30.2 hours |
| 100W | 17.7 hours | 15.1 hours |
| 200W | 8.9 hours | 7.5 hours |
| 500W | 3.5 hours | 3.0 hours |
| 1000W | 1.8 hours | 1.5 hours |
Runtime estimates are illustrative calculations, not guaranteed test results. The 85% usable-energy assumption accounts for potential operating losses and reserves. Actual results may differ substantially, particularly when using an inverter or high-current equipment.
Storage, Care, and Safety
- Store in a dry, cool, well-ventilated location within the specified storage temperature range.
- Avoid prolonged exposure to excessive heat, direct sunlight, moisture, and physical damage.
- For long-term storage, follow the manufacturer's recommended storage charge level and periodically inspect and recharge the battery as necessary.
- Do not short-circuit, puncture, crush, disassemble, or expose the battery to fire.
- Use properly sized wires, connectors, and suitable external circuit protection for your application.
- Do not charge a damaged, swollen, overheated, or otherwise abnormal battery.
- Recycle used lithium-ion batteries through an appropriate battery recycling facility. Do not place them in household trash or ordinary recycling bins.
