The 1500 mAh Rechargeable Battery and 1800 mAh High-Discharge Battery variants maintain stable capacity output throughout their lifespan, with a minimum capacity threshold that exceeds industry averages. Whether used in low-power devices or moderate-demand equipment, the battery pack ensures consistent performance without sudden power drops, making it ideal for long-term use.
As a wide temperature range battery, it excels in extreme environments: supporting charging at 0~60℃ (60±25% R.H.) and discharging at -20~60℃ (60±25% R.H.). This flexibility allows it to operate reliably in cold outdoor settings (e.g., winter camping gear) or high-temperature industrial environments, outperforming conventional batteries with narrow temperature limits. Note: Charging below 0℃ may reduce capacity and cycle life, so avoid extreme low-temperature charging.
With a maximum continuous discharge current of 3C (4500mA for 1500mAh variant), the battery pack powers high-demand devices such as portable tools, drones, and emergency lighting. Its robust discharge capability ensures that even power-hungry equipment receives sufficient current to operate at peak efficiency.
Our long cycle life battery is built to withstand repeated charge-discharge cycles. When stored properly (-20~25℃, 60±25% R.H.), it retains capacity for extended periods—simply charge once every 6 months (or every 3 months for packs with protection circuits) to maintain optimal performance. This makes it a cost-effective choice for applications requiring infrequent but reliable power.
As a safe LiFePO4 Battery, it features inherent thermal stability and is certified to UN 3480 standards, ensuring compliance with global transportation and safety regulations. The LiFePO4 chemistry minimizes the risk of overheating or thermal runaway, providing peace of mind for both consumer and industrial use.
Ideal for powering small to medium consumer devices, including portable speakers, digital cameras, handheld gaming consoles, and wireless headphones. The 1500 mAh variant balances portability，while the 1800 mAh option extends usage time for devices used throughout the day.
Perfect for outdoor enthusiasts, the battery pack powers camping lanterns, GPS devices, portable chargers, and heated clothing. Its wide temperature tolerance ensures reliable performance in mountainous regions, cold winters, or hot desert environments.
Serves as a backup power source for emergency lights, portable medical devices (e.g., small oxygen concentrators), and home security systems. The fast-charging capability allows quick recharging during power outages, while its stable discharge ensures critical devices remain operational when needed most.
Compatible with low-voltage industrial equipment, such as wireless sensors, small motors, and handheld industrial tools. The high discharge current and low internal resistance make it suitable for continuous operation in manufacturing, construction, and maintenance settings.
Every Cylindrical LiFePO4 Battery 18650 undergoes rigorous testing for capacity, internal resistance, voltage, and temperature performance. We ensure that each battery pack meets the same high standards, with no deviations in key parameters—guaranteeing reliability and compatibility across applications.
Our battery packs are fully certified to UN 3480, meeting international safety and transportation requirements. This certification allows seamless shipping worldwide, making it easy for businesses to source reliable batteries for global markets.

Our team of battery experts provides comprehensive technical assistance, including guidance on charging methods, storage practices, and compatibility with your devices. We are committed to helping you maximize the lifespan and performance of your 6.4V LiFePO4 Battery Pack.
The nominal voltage of the battery pack is 6.4V, which is formed by two 3.2V LiFePO4 cells in series. The individual cell charge voltage is 3.65V±0.03V.
The maximum continuous charge current is 1C (1500mA for 1500mAh, 1800mA for 1800mAh), and the maximum continuous discharge current is 3C (4500mA for 1500mAh, 5400mA for 1800mAh).
Store the battery pack in a dry environment at -20~25℃ (60±25% R.H.). Do not store for more than 6 months without charging—charge once every 6 months (or every 3 months for packs with protection circuits) to preserve capacity.
Charging temperature: 0~60℃ (60±25% R.H.); Discharging temperature: -20~60℃ (60±25% R.H.). Avoid charging below 0℃ to prevent capacity loss and reduced cycle life.
Using the standard charging method (0.2C constant current), the charging time is approximately 6 hours. For fast charging (1C current), the time is reduced to about 1.5 hours (reference values).
