FEATURES
Massive 20.48KWh Capacity: A LiFePO4 Lithium Battery That Powers Entire Operations
At the heart of this power box lies a 51.2V 400Ah LiFePO4 Lithium Battery delivering 20.48KWh of energy—enough to run multiple high-demand devices simultaneously. From construction tools (e.g., angle grinders, air compressors) to event equipment (sound systems, lighting rigs) or emergency medical devices, this LiFePO4 Lithium Battery system eliminates the need for multiple smaller batteries or noisy generators.

 

6000+ Cycles: A LiFePO4 Lithium Battery That Delivers Long-Term Value
Durability is non-negotiable for commercial power solutions, and this LiFePO4 Lithium Battery system excels. It achieves over 6000 charge-discharge cycles (at 25℃, 0.5C/0.5C, 100% DOD) with remaining capacity exceeding 70%—a lifespan 10x longer than lead-acid batteries (typically 500-1000 cycles). For businesses, this means fewer replacements, lower maintenance costs, and a higher return on investment over time.

Triple Charging Options: Keep Your LiFePO4 Lithium Battery Topped Up Anywhere
Flexibility is key for portable power, and this LiFePO4 Lithium Battery system offers three convenient charging methods to minimize downtime:
AC 230V inlet (30A): Reaches 80% charge in 3.5 hours, 100% in 4.5 hours—ideal for overnight charging at job sites or event venues.
Solar PV (5.8kW max): Connect to solar panels (MPPT voltage range 65-245VDC) for off-grid charging; perfect for remote locations like mining camps or rural construction sites.
External fast charger (320A Rema interface): Hits 80% charge in just 2.5 hours, 100% in 3 hours 10 minutes—critical for time-sensitive operations that can’t wait for slow charging.


All-Weather Performance: A LiFePO4 Lithium Battery That Works in Extreme Conditions
Unlike fragile batteries that fail in harsh environments, this LiFePO4 Lithium Battery system thrives:
Charge temperature: 0℃~60℃ (charges efficiently in cold warehouses or hot desert job sites).
Discharge temperature: -20℃~60℃ (powers equipment in freezing winters or scorching summers).
Whether you’re working in a snow-covered construction zone or a sun-baked outdoor event, this LiFePO4 Lithium Battery system maintains consistent performance—no more interrupted operations due to weather.

 

Versatile Output Interfaces: A LiFePO4 Lithium Battery for Every Device
This LiFePO4 Lithium Battery system comes equipped with a full suite of industry-standard outputs to connect all your gear:
3x 15A 230V AC sockets (RCBO-protected): For power tools, appliances, and heavy-duty equipment.
2x USB-A (QC3.0, 18W): Fast-charging for phones, tablets, and small electronics.
2x USB-C (PD3.0, 55W): Powers laptops, cameras, and high-demand portable devices.
2x Solar Input Touch-Safe Connectors: Secure, easy connection to solar panels.
1x 32A 230V Trickle Charge Inlet: For maintaining charge during long-term storage.

 

The EcoLite 8KW/20KWh Portable Power Box’s versatility, power, and durability make it the perfect LiFePO4 Lithium Battery solution for a range of commercial and industrial use cases:

Emergency Response & Disaster Relief
Construction & Job Sites
Remote Mining & Agriculture
