32140 LiFePO₄ batteries are emerging as a powerful alternative to traditional lithium-ion formats like 18650 and 32700. With a larger diameter (32mm) and length (140mm), the 32140 cell delivers higher capacity, improved thermal stability, and longer cycle life—making it ideal for high-performance energy storage systems, solar applications, and electric mobility.
As a relatively new large-format cylindrical cell, the 32140 is not yet mass-produced by many manufacturers. While you’ll find dozens of sellers on platforms like Alibaba, the majority are trading companies, not real battery producers. This often leads to higher costs, uncertain supply chains, and weak technical support.
If you’re serious about sourcing 32140 LiFePO₄ batteries at scale, it’s crucial to partner directly with a qualified cell manufacturer. Below are three proven producers who offer genuine 32140 cells with verified production capabilities.

FAQs
What is a 32140 Battery?
32140 refers to a cylindrical lithium iron phosphate (LiFePO₄) cell with a diameter of 32mm and a height of 140mm. Compared to 32700 or 18650 cells, it provides:
● Larger capacity and surface area
● Higher power output
● Lower internal resistance
● Better heat dissipation
● Longer service life
What are common applications of 32140 cells?
● Home and commercial energy storage systems (ESS)
● Off-grid solar battery banks
● Low-speed electric vehicles (e-bikes, e-rickshaws)
● Industrial equipment requiring high discharge rates
Are 32140 batteries safe to use in solar energy storage systems?
Yes. 32140 LiFePO₄ cells are known for excellent thermal stability, long cycle life (3,000–5,000+ cycles), and low risk of thermal runaway. They are widely used in solar ESS applications and off-grid systems.
Why Source Directly from Manufacturers?
Choosing a real 32140 cell manufacturer over a trading intermediary means:
● Lower pricing with fewer middlemen
● Better technical and after-sales support
● More consistent quality and performance
● Access to customization (pack format, voltage, BMS)
Whether you’re developing energy storage systems or integrating cylindrical cells into your hardware, working directly with a producer helps ensure better control and long-term value.
Why are there so few manufacturers of 32140 batteries?
The 32140 format is a relatively new cylindrical cell type, mainly adopted by newer energy storage projects. Its specialized tooling and production lines are not yet widely available, which limits the number of true cell manufacturers in this space.
