18650 6S2P 22.2V 4400mAh Lithium-Ion Battery Pack
$32.00
High-performance 18650 lithium-ion battery pack in 6S2P configuration, delivering 22.2V nominal voltage and 4400mAh capacity. Built with matched Grade A 18650 cells and a protected BMS for safe, stable power delivery. Ideal for power tools, portable equipment, medical devices, and custom OEM/ODM battery solutions.
Full Description
The 18650 6S2P 22.2V 4400mAh Li-ion battery pack is engineered for applications that demand reliable mid-capacity power in a compact form factor. Using six cells in series (6S) and two in parallel (2P), this configuration balances voltage output with extended runtime, making it a versatile choice for both consumer and industrial equipment.
Each pack is assembled from capacity- and internal-resistance-matched Grade A 18650 cells, ensuring consistent discharge performance and a longer usable cycle life. An integrated BMS (Battery Management System) provides overcharge, over-discharge, overcurrent, and short-circuit protection, along with optional temperature monitoring for added safety.
HNF Battery supports full customization — including connector type, wire gauge and length, PCB/BMS specification, and enclosure/heat-shrink finish — to match your product’s exact requirements. OEM/ODM services are available for qualified B2B buyers.
