IP65 206Ah 25.6V LiFePO4 Battery 5.27kWh For High Capacity Backup Storage
5.27kWh 25.6V 206Ah LiFePO4 Battery for High Capacity Backup Storage
More Than 5kWh in a Single 25.6V Battery
This 25.6V 206Ah LiFePO4 battery provides 5273.6Wh of nominal stored energy, equivalent to approximately 5.27kWh. It is intended for compatible solar-storage, backup, UPS and inverter systems that need a larger energy reserve on a 25.6V battery platform.
The product offers more than twice the nominal energy of a 25.6V 100Ah battery. This can reduce the number of battery enclosures required when a project needs approximately 5kWh of storage.
When 5.27kWh Is a Better Starting Capacity
A larger starting capacity may be appropriate when the backup target includes several essential loads, longer operating hours or reduced dependence on frequent recharging.
Longer Backup Objective
The higher nominal energy can extend runtime compared with a 2.56kWh battery under similar operating conditions.
Single-Enclosure Layout
The full capacity is provided within one 523 × 269 × 218mm battery enclosure.
Defined Shipping Data
The packaged battery weighs 37.5kg gross, allowing logistics and site handling to be planned before shipment.
Calculate Energy and Power Separately
The 5.27kWh rating indicates nominal stored energy. The inverter determines maximum AC output power, and its battery-side current must remain within the battery’s 100A continuous discharge limit.
Actual backup time depends on the average load, inverter efficiency, battery settings, operating temperature and cable losses. High-power heating or motor loads can shorten runtime substantially.
Charging and Installation
The battery supports up to 50A of continuous charging and uses a listed 28.0V floating-charge voltage. The charger should support the required lithium profile.
The battery weighs 35.5kg net and should be installed on a stable supporting surface with suitable access to the M8 terminals and protection equipment.
The final charger low-voltage and charging settings should be confirmed for the selected system before commissioning.

5kWh-Class Battery FAQ
Is the exact battery capacity 5kWh?
The formal nominal energy is 5273.6Wh, equal to approximately 5.27kWh.
Does it include an inverter charger?
No. The charging and conversion equipment must be selected separately.
Can the battery support a whole home?
Suitability depends on the household load, inverter rating and required operating time.
Can it discharge at 150A continuously?
No. Continuous discharge is limited to 100A.
What is needed for backup sizing?
Provide the load list, average power, startup demand and required operating hours.
