25.6V 280Ah LiFePO4 Battery for Solar Energy Storage, UPS, RV and Industrial Power Systems

The 25.6V 280Ah LiFePO4 battery delivers exceptional reliability and performance. Featuring a long cycle life of over 3,000 cycles, outstanding thermal stability, and built-in BMS for enhanced safety, it’s ideal for solar energy storage, RVs, marine, and off-grid systems. Maintenance-free, lightweight compared to lead-acid, and eco-friendly, this battery offers consistent power output and deep discharge capability without compromising longevity or safety.

Q1: What are the key specifications of this battery?

A: This battery has a nominal voltage of 25.6V, a rated capacity of 280Ah, and uses high-quality LiFePO4 (Lithium Iron Phosphate) cells. It offers a cycle life of 3,000–6,000 cycles (at 80% DoD), built-in BMS (Battery Management System), and operates within a wide temperature range.

Q2: What applications is this battery suitable for?

A: Ideal for solar energy storage, off-grid power systems, RVs, marine use, telecom backup, and industrial equipment. Its high capacity and stable chemistry make it perfect for deep-cycle, long-duration applications.

Q3: Does it include a Battery Management System (BMS)?

A: Yes. The battery comes with an integrated smart BMS that provides protection against overcharge, over-discharge, overcurrent, short circuit, and high/low temperature—ensuring safety and longevity.

Q4: What’s the expected lifespan?

A: With proper use and maintenance, this LiFePO4 battery typically lasts 7–10 years or more. It retains over 80% of its capacity after 3,000+ cycles at 80% depth of discharge (DoD).

Q5: Can I connect multiple batteries in series or parallel?

A: Yes. You can connect up to 4 batteries in parallel to increase capacity (e.g., 25.6V 1120Ah). For higher voltage systems (e.g., 48V), check compatibility—this 25.6V unit is designed as a 8S configuration and is not intended for series connection unless specified by the manufacturer.

Q6: What charging voltage and current should I use?

A: Use a LiFePO4-compatible charger with a recommended charge voltage of 29.2V ± 0.2V. The standard charge current is 56A (0.2C), with a maximum of 140A (0.5C). Always follow the charger manufacturer’s guidelines.

Q7: Is this battery safe for indoor use?

A: Yes. LiFePO4 chemistry is inherently non-toxic, non-flammable, and thermally stable. Combined with the BMS, it’s one of the safest lithium battery options for indoor installations—such as homes, cabins, or server rooms.

Q8: What certifications does this battery have?

A: It complies with international standards including UN38.3, CE, RoHS, IEC 62619, and MSDS. Specific certifications may vary by region—contact us for documentation.

Q9: What’s included in the package?

A: The package includes the 25.6V 280Ah LiFePO4 battery, user manual, warranty card, and terminal bolts/nuts. Cables and chargers are sold separately unless part of a bundle.

Q10: What is the warranty?

A: We offer a 3-year limited warranty covering defects in materials and workmanship under normal use. Full terms are available upon request.
