LiFePO4 21700 Cylindrical Cell 3.2V 6Ah — Lithium Iron Phosphate Battery | Pakistan

The LiFePO4 21700 cylindrical cell is the workhorse of modern energy storage in Pakistan — compact, thermally stable, and built to survive the country’s harshest conditions without degradation. Measuring just 21mm in diameter and 70mm in height, this 6Ah lithium iron phosphate cell delivers a nominal 3.2V with a safe operating window of 2.8V (minimum) to 3.65V (maximum). Unlike conventional lithium-ion chemistry that risks thermal runaway above 60°C, LiFePO4 remains chemically stable up to 270°C — making it the only safe choice for Pakistan’s summer temperatures that regularly exceed 45°C in Sindh, Punjab, and Balochistan. With over 2,000 charge-discharge cycles at 80% depth of discharge, this single cell outlasts an entire rack of lead-acid batteries while weighing a fraction of the same.

At Newon Lighting Pakistan, we don’t just sell cells — we build complete custom battery packs tailored to your exact requirements. Whether you need a compact 12V pack for home system in Quetta, a 48V backup bank for a commercial UPS in Lahore, a lightweight pack for an electric Bike across Karachi, or a high-capacity storage system  in Gilgit-Baltistan, our engineering team assembles 21700 cylindrical cells into professionally welded, BMS-protected, ready-to-install battery packs of every voltage, capacity, form factor, and configuration across Pakistan. Each pack is designed according to customer demand and tested before dispatch.

Why 21700 Cylindrical LiFePO4 for Pakistan?

The 21700 form factor hits the sweet spot between energy density and thermal management. It’s larger than the common 18650 cell (more capacity per cell, fewer cells needed per pack) yet smaller than bulky prismatic cells (easier to arrange in tight enclosures, better airflow between cells). For Pakistan’s energy landscape — 8–12 hours of daily loadshedding, grid voltage swinging between 170V–260V, and summer temperatures exceeding 50°C — this cell format delivers:

• Thermal safety: LiFePO4 chemistry is inherently stable — no risk of fire or explosion even in Pakistan’s extreme summer heat. Safe for indoor UPS installations, residential solar systems, and enclosed telecom cabinets.
• Long cycle life: 2,000+ cycles at 80% DOD means 5–7 years of daily charge-discharge — compared to 300–500 cycles for lead-acid batteries. Lower total cost of ownership despite higher initial investment.
• Compact energy density: 6Ah in a 21×70mm cylinder means fewer cells per pack, less wiring, smaller enclosures, and lower assembly cost compared to smaller formats.
• Flat discharge curve: Voltage remains stable between 3.2V–3.0V for 90% of the discharge cycle, ensuring consistent power delivery to inverters, motors, and sensitive electronics.
• Zero maintenance: No water topping, no acid handling, no ventilation requirements. Install and forget.
