Performance & Advantages
Why Choose 32650 LiFePO4 Battery Cells?
High Energy per Cell
Larger format delivers higher capacity compared to 18650 or 26650 cells. With capacities ranging from 5Ah to 6.5Ah, 32650 cells provide more energy in a single unit, reducing the total number of cells needed for your battery pack design.
Long Cycle Life
LiFePO4 chemistry supports thousands of charge–discharge cycles. Our 32650 cells are rated for over 2000 cycles at 80% DOD, with premium grades achieving 3000+ cycles. This translates to 5-10 years of reliable service life.
Enhanced Safety
Excellent thermal stability, low risk of thermal runaway. LiFePO4 chemistry is inherently safer than other lithium-ion chemistries, with superior thermal and chemical stability even under abuse conditions.
Stable Voltage Output
Ideal for energy storage systems and power-critical applications. The flat discharge curve maintains consistent voltage throughout the discharge cycle, ensuring stable performance for your devices.
Lower System Complexity
Fewer cells needed in series/parallel configurations. The higher capacity per cell means you can build the same energy capacity with fewer cells, reducing BMS complexity, wiring, and overall system cost.

Frequently Asked Questions
What is the difference between 32650 and 18650 battery cells?
The main difference is size and capacity. 32650 cells (32mm diameter × 65mm length) offer 5-6.5Ah capacity, while 18650 cells (18mm × 65mm) typically provide 2.5-3.5Ah. This means 32650 cells have nearly double the capacity, allowing you to build battery packs with fewer cells, reducing system complexity and cost.
What is the typical cycle life of 32650 LiFePO4 cells?
Our 32650 LiFePO4 cells are rated for over 2000 cycles at 80% Depth of Discharge (DOD), with premium grades achieving 3000+ cycles. Under optimal conditions with proper BMS protection, the cells can last 5-10 years in typical applications.
Can you customize the battery pack configuration?
Yes! We offer full OEM/ODM services including custom voltage configurations (12V, 24V, 48V, 60V, etc.), capacity matching, BMS integration, and custom enclosures. Our engineering team can help design the optimal battery solution for your specific application.
What is the minimum order quantity (MOQ)?
For individual 32650 cells, the MOQ is typically 100 pieces. For custom battery packs, the MOQ varies depending on complexity, usually starting from 10-50 units. For sample orders and evaluation purposes, we can provide smaller quantities.
Do you provide technical support and after-sales service?
Absolutely! We provide comprehensive technical support including battery pack design consultation, BMS configuration, installation guidance, and troubleshooting. Our team is available via email, phone, and online chat to assist with any questions.
Are 32650 cells suitable for high-current applications?
Yes, 32650 LiFePO4 cells support high continuous discharge rates up to 3C (15-19.5A for a 5-6.5Ah cell). This makes them ideal for power tools, electric vehicles, and other high-current applications. We also offer high-power variants optimized for even higher discharge rates.
What certifications do your batteries have?
Our 32650 cells and battery packs comply with CE, RoHS, UN38.3, and MSDS standards. We can provide all necessary documentation for international shipping and customs clearance. Additional certifications (UL, IEC, etc.) can be arranged for large orders.
How should I store 32650 LiFePO4 cells?
Store cells in a cool, dry place at 40-60% State of Charge (SOC) and temperatures between 0-25°C. Avoid prolonged storage at full charge or complete discharge. For long-term storage (>6 months), check and recharge cells every 3-6 months to prevent over-discharge.
