Question 1

1. How much energy does a 25.6V 280Ah LiFePO4 battery store?

Accepted Answer

A 25.6V 280Ah battery stores 7168Wh of rated energy, equivalent to approximately 7.17kWh.
The theoretical energy is calculated as:
25.6V* 280Ah = 7168Wh.
Actual usable energy in a finished system depends on BMS settings, inverter efficiency, discharge current, temperature and the selected depth of discharge.

Question 2

2. Is a 25.6V LiFePO4 battery suitable for a 24V solar system?

Accepted Answer

Yes, it can be suitable for compatible 24V-class solar systems.
The battery has a nominal voltage of 25.6V and a recommended charge voltage of 29.2V. The solar charge controller or inverter must support the required LiFePO4 charging profile.
Compatibility should be confirmed before installation rather than assuming that every device labeled 24V is automatically compatible.

Question 3

3. How long can a 7.17kWh battery run my equipment?

Accepted Answer

Runtime depends on the total power consumption of the connected equipment.
A simplified theoretical calculation is:
Runtime = Battery Energy/Load Power
For example, a 1000W load would theoretically consume 1kWh per hour. Actual runtime will be lower after considering inverter efficiency, BMS limits and usable depth of discharge.

Question 4

4. What is the maximum discharge current of this battery?

Accepted Answer

The standard continuous discharge current is 75A, while the specified maximum continuous discharge current is 150A.
The final system must also be designed with suitable cables, terminals, fuses, circuit breakers and inverter input ratings for the required current.

Question 5

5. What inverter size can I use with this 25.6V battery?

Accepted Answer

Inverter selection should not be based only on battery capacity.
The inverter must be matched to: Battery nominal voltage Maximum DC input current Continuous load Starting surge current BMS current limit Cable size Protection device rating
For high-power inverter systems, provide the inverter model and load information so the battery configuration can be verified before ordering.

Question 6

6. How long is the cycle life of the 25.6V 280Ah battery?

Accepted Answer

The specified cycle life is more than 6000 cycles under a 0.5C test rate at 25Celsius and 80% depth of discharge.
Actual service life depends on depth of discharge, charge rate, discharge rate, operating temperature, storage conditions and charging strategy.

Question 7

7. Can the battery replace a 24V lead-acid battery bank?

Accepted Answer

It can replace many compatible 24V lead-acid battery systems, but it should not be treated as a direct plug-and-play replacement without checking the complete electrical system.
The charger, inverter, controller, cut-off settings and protection devices must support the LiFePO4 voltage profile.

Question 8

8. Can multiple 25.6V 280Ah batteries be connected in parallel?

Accepted Answer

Parallel connection can be considered when additional storage capacity is required, but the battery design must support parallel operation.
Before installation, confirm the permitted number of parallel packs, battery state-of-charge requirements, cable layout, protection design and BMS compatibility.
Do not assume unlimited parallel connection.

Question 9

9. Can this 25.6V battery be customized for OEM projects?

Accepted Answer

Yes.
As a custom LiFePO4 battery manufacturer, we can evaluate OEM requirements including voltage, capacity, discharge current, BMS, communication protocol, enclosure, terminal, cable, branding and packaging.
For accurate engineering evaluation, buyers should provide the application, required voltage, load current, peak current, installation dimensions, charger or inverter specification and estimated annual quantity.

Question 10

10. What information should I provide before requesting a quotation?

Accepted Answer

For an accurate battery recommendation and quotation, please provide:
Application
Required nominal voltage Required capacity or runtime Continuous load current Peak current
Charger specifications Inverter or controller model Installation dimensions Required communication protocol Connector or terminal requirement Certification requirement Estimated order quantity
Providing these details helps the battery supplier determine whether the standard 25.6V 280Ah platform is suitable or whether a custo.
