IFR26650 3.2V LT3500 11.2Wh LFP Cell – Extreme Low Temperature Series

Category: Low Temperature LFP Cells | Model: IFR26650 3.2V LT3500 | Voltage: 3.2V | Capacity: 3500mAh (11.2Wh) | Brand: WTS

Power your cold-climate applications with our high-performance IFR26650 3.2V LT3200 10.24Wh LFP Cell. Engineered for extreme low-temperature environments, this LiFePO₄ battery supports direct charging at -30°C without pre-heating and delivers over 90% discharge capacity at -50°C. Built for long cycle life and military-grade safety (GJB4477 certified), this cell is perfect for EVs, energy storage systems, military equipment, and outdoor applications in arctic conditions.

Key Highlights:

-30°C Direct Charging: No pre-heating required – charge directly below freezing without lithium plating, ensuring consistent cycle life.
-50°C High-Efficiency Discharge: Over 90% capacity at -50°C (down to 1.5V) and 95% capacity at -20°C under high current.
Wide Operating Temperature: Reliable discharge from -50°C to +60°C, covering nearly all industrial and outdoor scenarios.
5-10C Continuous Discharge: Sustained high-rate discharge up to 10C even at low temperatures, meeting high-power demands.
GJB4477 Certified Safety: Passes military-grade nail penetration and gunshot tests — no fire, no explosion, maximum reliability.
