14.8V 2200mAh 18650 Li-ion Battery Pack 4S1P Rechargeable Lithium Battery

This 14.8V 2200mAh 18650 battery pack is a rechargeable lithium-ion power solution built with 18650 cylindrical cells in a 4S1P configuration, delivering a capacity of 2200mAh and 32.56Wh of total energy. Engineered for dependable everyday use, this 14.8V 2200mAh 18650 battery pack features a JST-style connector with an insulated lead wire for straightforward integration into host devices such as robotic vacuums, handheld tools, and other portable equipment.

The pack charges at 0.2C (440mA) with a CV cutoff of 16.8V, completing a full charge in ≤5.5 hours. Standard discharge current is 0.2C (440mA), with a continuous maximum discharge of 1C (2200mA), a discharge cut-off voltage of 11V, and discharge over-current protection triggering between 8-16A.

Operating temperature range is 0~45°C for charging and -20~60°C for discharging, with internal resistance ≤320mΩ (AC 1kHz). The complete pack weighs 195±5g.

Specifications

Applications of This 14.8V 2200mAh 18650 Battery Pack

This 14.8V 2200mAh 18650 battery pack is designed for devices that need stable, mid-capacity power in a compact footprint. Typical applications include robotic vacuum cleaners, handheld cleaning tools, portable medical carts, industrial handheld scanners, and other equipment that runs on a 14.8V nominal platform. Because the pack uses standard 18650 cylindrical cells in a 4S1P layout, it offers a good balance of energy density, weight, and cost for OEM designs.

Engineers who need a different capacity or form factor can browse the full 14.8V (4S) lithium battery pack collection to compare configurations, or reach out to our team for custom OEM options such as connector type, cable length, PCM/BMS parameters, and pack dimensions.

Safety and Certification
