25.6V 280Ah Lithium Iron Phosphate Energy Storage Battery

25.6V 280Ah LiFePO4 Energy Storage Battery | Wholesale Factory

25.6V 280Ah LiFePO4 battery, 7.16kWh capacity. High-density prismatic cells, 6000+ cycle life, smart BMS. Factory direct, MOQ 1 unit, OEM/ODM ready.

Product Overview & System Integration

This 25.6V 280Ah Lithium Iron Phosphate (LiFePO4) battery module provides a 7.16kWh energy foundation for mid-to-large scale power systems. Utilizing high-capacity 280Ah prismatic cells, the module is designed for direct integration into 24V busbar systems or series-parallel configurations for 48V/96V industrial storage. As a direct manufacturer, we provide secondary development for communication integration (CAN/RS485), enabling direct interfacing with standard hybrid inverters. We offer specific modifications for custom PCB shielding and high-current terminal output requirements.

Material & Technical Specifications

Quality Control & Global Standards

Our factory implements a strict 4-stage testing protocol: initial cell voltage matching, resistance grouping, 100% capacity cycle testing, and 24-hour load aging test. Every unit complies with IEC 62619, CE, and RoHS standards. We provide full documentation for UN38.3 (transportation of dangerous goods) to ensure seamless customs clearance for international buyers.

Packaging & Logistics Safety

Lithium batteries are classified as Class 9 hazardous goods. We use reinforced double-layer corrugated boxes with high-density flame-retardant foam inserts. For wholesale orders, batteries are secured on ISPM-15 certified fumigated wooden pallets with heavy-duty steel strapping and moisture-proof wrap to prevent terminal damage or short circuits during sea transit.

Typical Application Scenarios

24V Solar Power Plants: Reliable storage for remote, off-grid infrastructure.

Industrial Back-up: UPS for data centers and commercial telecommunication hubs.

RV & Marine Power: High-capacity energy banks for specialized electric mobility.

Peak Shaving: Commercial energy management systems for local microgrids.

FAQ

Q: How does this 280Ah battery module perform in high-vibration mobile environments?

A: The internal prismatic cells are secured using high-strength epoxy resin plates and vibration-dampening separators. This construction minimizes movement during transport or mobile installation, preventing mechanical failure or terminal fatigue. We subject all modules to standard shock-vibration testing to ensure integrity for marine and industrial vehicle applications.

Q: Can this module be integrated into an existing 48V solar setup?

A: Yes, two 25.6V 280Ah modules can be wired in series to create a stable 51.2V 280Ah system. We recommend using a high-quality active balancer to maintain voltage uniformity between the two modules throughout their operational lifespan, ensuring consistent BMS communication and charging efficiency across the entire string.

Q: What are the requirements for OEM logo and color customization on bulk orders?

A: We offer laser-etched branding on the enclosure and custom color-coding for high-volume orders. MOQ for custom exterior finishes is 20 units. Our engineering team provides mechanical drawings for your review before production, ensuring the branding aligns with your market's aesthetic requirements and internal quality documentation.
