3.84kWh 12.8V 300Ah LiFePO4 Backup Battery For UPS Solar Communication Applications

3.84kWh 12.8V 300Ah LiFePO4 Battery for Long Duration Backup Power

This 12.8V, 300Ah LiFePO4 battery provides 3.84kWh of nominal energy for longer-duration UPS, solar, emergency and communication backup applications.

It is the highest-capacity 12V option in this product group and is intended for projects that need more stored energy without changing to a 24V-class platform.

Extended Energy within a 12V Platform

The 300Ah capacity can extend the potential operating time of selected lighting, security, communication and inverter loads. Actual runtime depends on total consumption, conversion efficiency and retained battery reserve.

A larger battery also requires sufficient charging capacity. The solar controller or AC charger should restore daily energy use within the available charging period.

200A Current and 2.56kW Power Platform

Rated charge and discharge current is 200A, while the battery-side rated power is 2.56kW. A 205A, one-second current reference is also listed.

The higher capacity increases energy storage but does not raise the rated power above the 200Ah version. Buyers should therefore select this model primarily for longer operating time.

Long-Duration Backup FAQ

What is the main advantage of the 300Ah version?

It provides the largest stored-energy reserve in the 12.8V series for a longer potential operating period.

Does the larger capacity increase output power?

Not in this specification. Rated battery power remains 2.56kW.

Can it store solar or wind energy?

Yes, when connected through compatible charging equipment with suitable lithium battery settings.

How should charging capacity be selected?

Match the charger or solar controller to the energy used and the time available to recharge the battery.

What data helps calculate backup time?

Provide the continuous load, daily operating hours, inverter efficiency and required retained reserve.
