High-Capacity 18650 LiFePO4 Battery – Reliable Power for Demanding Applications

Premium-grade lithium iron phosphate (LiFePO4) chemistry ensures exceptional thermal stability and extended cycle life (2000+ cycles). Each cell delivers a consistent 2500mAh capacity at 3.7V nominal voltage (9Wh energy output), optimized for rapid charging with minimal voltage drop.

Robust steel casing with precision laser welding resists corrosion and mechanical stress. Integrated PTC protection circuit prevents overcharge/overheating, ideal for high-drain devices like vaping mods, tactical flashlights, solar power banks, and electric bike battery packs.

Factory-direct pricing with bulk discounts – wholesale quantities available for OEMs and resellers. Ships in anti-static packaging with full IEC62133 certification. Compatible with most 18650 devices requiring stable voltage under heavy loads.

Key advantages vs. standard Li-ion: Safer operation, wider temperature range (-20°C to 60°C), zero memory effect. Minimal self-discharge (3% monthly) maintains charge during storage.
