High-performance 3.2V LiFePO4 Cylindrical Battery Cell
Premium-grade lithium iron phosphate chemistry ensures exceptional thermal stability and extended cycle life (2000+ cycles at 80% DoD). Precision-welded terminals with anti-corrosion nickel plating guarantee secure connections.
Ultra-dense energy storage
Compact 15Ah/20Ah capacity delivers 30% higher energy density than standard cells. Robust steel casing withstands 12MPa radial pressure, ideal for solar arrays, EV conversions, and industrial backup systems.
Engineered for extreme conditions
Operates flawlessly from -20°C to 60°C with built-in CID pressure relief. UL1642-certified separator prevents thermal runaway. Perfect for marine applications, off-grid power, and medical equipment.
Bulk procurement advantage
Direct-from-factory pricing with MOQ flexibility. Customizable terminal configurations and batch testing reports available. Ships with ISO-certified moisture-proof packaging.
Seamless integration
Standard 33140/33138/40135 sizes compatible with most BMS systems. Spot-welding ready with laser-etched QR codes for traceability. Backed by 5-year performance warranty.
