Product Overview
This 2S1P 18650 lithium-ion battery pack provides a nominal voltage of 7.4V and a rated capacity of 2000mAh (14.8Wh), assembled with two genuine HONGLI ICR18650-2000mAh grade A cylindrical cells connected in series. It is purpose-built for backup power applications, delivering stable standby energy for broadband routers, security cameras, alarm systems, emergency lighting, POS terminals, mini UPS units and other equipment that must keep running during mains power failure.
Each cell is capacity-sorted and voltage-matched before assembly, and the pack is equipped with an integrated BMS protection board against overcharge, over-discharge, over-current and short circuit, which extends cycle life and reduces after-sales risk for finished equipment manufacturers.

Key Features
1. Genuine HONGLI ICR18650 Grade A Cells
Built with authentic HONGLI ICR18650-2000mAh cells (code-verified, no refurbished or mixed cells). Strict capacity sorting and internal resistance matching guarantee true 2000mAh capacity and consistent performance in every batch.
2. Stable 7.4V Output under Load
Low internal resistance and matched cells keep the output voltage steady during continuous discharge, preventing sudden shutdown or unstable operation of backup-powered devices.
3. Full BMS Multi-Protection
The integrated protection circuit monitors overcharge, over-discharge, over-current and short circuit in real time, improving safety and significantly lowering after-sales risk.
4. Reliable Long-Standby Backup Duty
Low self-discharge rate keeps the pack charged and ready for long idle periods, making it an ideal drop-in power source for emergency and standby applications.
5. OEM / ODM Customization Support
Custom wire length, connectors, PCB lead position, PVC/heat-shrink color, logo silk printing and packaging are all available. Small-batch sampling and mass production are both welcome.
Wide Applications
• Backup power for broadband routers and fiber optic modems
