18650 1S2P Lithium Battery Pack - 3.7V 5200mAh：

Product Description

The Parallel Advantage
Unlike series configurations which increase voltage, this 1S2P pack is engineered to double the capacity while maintaining the standard single-cell lithium-ion voltage of 3.7V. This design is perfect for devices that operate on ~3.7V logic but suffer from short battery life with a single cell.

Performance & Safety
Built with matched cells to ensure balanced current sharing and longevity, this pack includes a tailored Protection Circuit Module (PCM). The PCM safeguards against the unique risks of parallel configurations, such as reverse current flow between cells, while providing standard over-voltage and over-current protection.

Core Applications

This pack is specifically designed for:

Single-Cell Devices with High Drain: Upgrading flashlights, portable fans, or sensors that need longer runtimes.
Low-Voltage, High-Capacity Systems: Portable audio equipment (speakers, amplifiers), low-power IoT hubs, and data loggers.
Backup Power for 3.7V Circuits: As an extended-life backup for microcontrollers, Raspberry Pi projects, or security systems.
Custom Power Banks: The foundational unit for building custom, high-capacity USB power banks.
Solar Light Storage: As an efficient, high-capacity battery for solar-powered garden or security lighting.
