Certifications:

Certification 1 Certification 2 Certification 3
The 24V / 25.6V lithium battery is a high-efficiency battery pack built from multiple LiFePO4 cells. Depending on the capacity, the configuration varies (e.g., 8S1P, 8S2P). Compared to traditional batteries, it offers a more compact design, longer cycle life, and greater cost-efficiency, making it an ideal upgrade from lead-acid, AGM, or GEL batteries.
HEXI 24V lithium batteries are available in wall-mounted, rack-mounted, portable, and plug-and-play models. We also support customized solutions tailored to your specific energy storage needs.

 HEXI 24V 280Ah lithium batteries are equipped with an advanced Battery Management System (BMS) featuring active balancing to ensure consistent cell performance and stable power output. The BMS provides full protection against overcharging, over-discharging, overcurrent, short circuit, and temperature fluctuations, ensuring reliable and safe operation. The casing is made of durable ABS and PC material, offering waterproof and corrosion-resistant features ideal for both indoor and outdoor use.


Lightweight and Compact 
Thanks to its high energy density the HEXI 24V 280Ah LiFePO4 battery delivers significantly more energy than lead-acid batteries while weighing only one-third as much. Its compact internal structure minimizes space usage, and the top-mounted handle makes installation and transport easier and more efficient.

Long Service Life 
Built with Grade A LiFePO4 cells and optimized structural design, the HEXI 24V 280Ah battery offers over 6,500 deep cycles with minimal capacity loss. It features a low self-discharge rate, making it a far superior and longer-lasting alternative to traditional lead-acid, AGM, or GEL batteries.

Extended Runtime & Flexible Configuration 
Each 24V 280Ah battery provides a total energy capacity of 6.72kWh, equivalent to two 12V 280Ah batteries. This not only simplifies wiring but also reduces installation time. The battery supports series (up to 51.2V) and parallel connections (up to 4 units) to meet larger power demands. With up to 99% usable capacity, it outperforms lead-acid batteries in runtime and efficiency.



Fast & Flexible Charging – 3 Methods 
HEXI batteries are compatible with multiple charging methods and charge fully in just 3 to 5 hours:
1. 29.2V LiFePO4 charger
2. Solar panels via MPPT controller
3. Inverter charger
No memory effect and high charge efficiency ensure fast, safe, and flexible energy management.

Eco-Friendly Energy Choice 
HEXI 24V 280Ah LiFePO4 batteries are **non-toxic, maintenance-free, and 100% environmentally friendly, containing no lead, acid, or harmful heavy metals. They are an ideal green power solution for home energy storage, off-grid solar systems, RVs, camping, and backup power. Compatible with most 24V inverters and solar setups.

OEM / ODM Customization Available 
As a professional LiFePO4 battery manufacturer, HEXI provides OEM and ODM solutions to fit your unique project requirements, including: 
- Custom voltage, capacity, and dimensions 
- Bluetooth monitoring 
- Low-temperature self-heating 
- LED indicators & smart BMS 
- Custom casing colors and private label branding 

All batteries come with international certifications such as CE, MSDS, UN38.3, IEC, and include a 10-year warranty. We offer factory-direct pricing, fast lead times, and responsive technical support.

1. Can I Use the 24V 280Ah Battery with My Inverter?

-Yes, the HEXI 24V 280Ah LiFePO4 battery is compatible with most 24V inverters, including pure sine wave inverters used in solar, RV, or off-grid systems. Just make sure:
-Your inverter supports 24V nominal input
- The inverter's peak current doesn't exceed the battery's BMS limit(usually around 100A or per spec)
Always double-check your inverter manual or contact us with the model details for confirmation.


2. How Long Can a 24V 280Ah Battery Power My Appliances?

The battery stores 7168Wh (6.72kWh) of energy. Here are some estimates:
- A 500W fridge could run for 13+ hours
- A 1000W washing machine could run for 6+ hours
- A 200W fan could run for 30+ hours
Actual runtime depends on power load, inverter efficiency, and environmental factors. Feel free to send us your appliance list and we’ll help you calculate.


3. Is It Okay to Leave the Battery Outdoors or in a Garage?

The battery must be kept in a dry, well-ventilated location, ideally indoors.
- Avoid direct sunlight, moisture, or freezing conditions
- If placed in a garage or shed, ensure temperature stays between 0°C to 45°C (32°F to 113°F)
- For outdoor use, we recommend a weatherproof battery box or cabinet
Temperature extremes may trigger BMS protection or reduce lifespan.

4. How Do I Store the Battery If I’m Not Using It for Months?

If you're storing the battery for a long period:
1. Charge it to around 50–60% (not fully)
2. Turn off all connected devices
3. Store it in a cool, dry place between 10°C and 30°C (50°F–86°F)
4. Recharge it every 3–6 months** to maintain health
Proper storage ensures your battery stays healthy even during long idle periods.

5. Can I Replace My Lead-Acid Battery with This LiFePO4 Model?

Yes, you can upgrade directly. The HEXI 24V 280Ah battery is a drop-in replacement for many lead-acid systems. Benefits include:
- 3x longer lifespan
- Faster charging
- 60% lighter weight
Make sure your charge controller or inverter supports LiFePO4 charging profiles for optimal performance.

6. What Certifications Does This Battery Come With?

Our 24V 280Ah lithium batteries are manufactured with Grade A cells and come with:
- CE & UN38.3 certification for international transport and safety
