What is an Lifepo4?
Benergy 32140 LiFePO4 cell (3.2V 15Ah) is a cylindrical lithium iron phosphate battery designed for applications requiring a balance of high power, long cycle life, and absolute safety. Unlike traditional lead-acid batteries, this LiFePO4 cell delivers stable performance across a wide temperature range and thousands of deep discharge cycles.
Key Specifications at a Glance:
Nominal Voltage: 3.2V
Capacity: 15Ah
Discharge Cut-off Voltage: 2.5V
Max Continuous Discharge Current: 30A (2C)
Internal Resistance: ≤ 3.0mΩ (low heat generation)
Max Charge Voltage: 3.65V
Operating Temperature: -20℃ to 60℃ (charge & discharge)
Why Choose This 32140 Cylindrical Cell?
High Energy Density & Power Delivery
Despite its compact cylindrical form factor, the 32140 LiFePO4 cell packs significant energy. It supports a 30A continuous discharge current, making it suitable for electric vehicles (EVs), e-bikes, power tools, and other high-drain devices.
Long Cycle Life for Cost-Effective Storage
With a stable lithium iron phosphate chemistry, this cell typically achieves 2000+ cycles at 80% depth of discharge (DoD). This translates to years of reliable service in solar energy storage systems and UPS backup applications, drastically lowering your total cost of ownership.
Built-in Safety & Thermal Stability
LiFePO4 chemistry is inherently safer than other lithium-ion types. The 32140 cell features low self-discharge rate, no thermal runaway risk under normal use, and excellent performance even at extreme temperatures (-20℃ to 60℃). It is also UN38.3 certified for safe transport.
Versatile Applications
Whether you are building a DIY battery pack for an off-grid solar system, upgrading an electric vehicle, or designing a smart grid / UPS backup, the 32140 LiFePO4 cell offers a reliable, drop-in ready solution. Its low internal resistance (6.5mΩ) ensures efficient charging and discharging with minimal energy loss.
Ideal For:
Electric vehicles (EV, golf carts, e-bikes)
Residential & commercial solar storage
UPS (uninterruptible power supply) systems
Smart grid energy storage
Portable power stations & DIY power walls
