Power your most demanding portable devices with this 3.7V 8800mAh NCM 18650 battery pack — a high-capacity 32.56Wh solution built from four premium 2200mAh NCM 18650 cells in a 1S4P configuration. Delivering a typical capacity of 8800mAh (minimum 8600mAh at 0.2C discharge), this pack delivers extended runtime for handheld instruments, medical devices, POS terminals, portable speakers, and custom OEM electronics.
Engineered for safety and reliability, each pack integrates a robust protection circuit module featuring the S8261DAI protection IC, dual PT2012 MOSFETs, and a 15A resettable fuse — providing comprehensive over-charge, over-discharge, over-current, and short-circuit protection. The cells are wrapped in blue PVC heat shrink and terminated with a pre-wired XH-4P reverse connector (UL1007 22AWG, black/black/red/red leads) for fast, polarity-correct integration.
Charging follows a standard CC/CV profile at 4.20V, with a standard charge current of 1.5A and a maximum charge of 5A. On discharge, the pack supports up to 5A continuous current, with a PCB cut-off at 3.0V to prevent deep discharge. At just 200 grams, it delivers exceptional energy density — over 32Wh in a compact form factor built around standard 18650 cells. Operating from 0°C to 45°C on charge and -20°C to 60°C on discharge, with over 300 charge cycles, the Antbatt 8800mAh pack is ready to power your product through the longest shifts.
