1S 3.7V Li-ion 1MOS 2A Battery Protection Board

Single-Cell (1S) Lithium Protection: Optimized for single-cell (S) 3.7 nominal / 4.2V peak charge lithium-ion, LiPo, and 18650 battery cells.

2A Continuous Discharge Rating: Engineered with a single power MOSFET (1 MOS) configuration delivering up to 2A continuous discharge current for low-power electronics.

Compact Strip Form Factor: Ultra-slim profile fits comfortably along cell edges, ideal for integration inside tight battery shrink wraps and compact enclosures.

Automated Multi-Protection Safety: Features onboard protection control IC providing instant cutoffs against overcharging, over-discharging, overcurrent, and short circuits.

Solder-Friendly Lead Tabs: Pre-configured solder pads (B+, B-, P+, P-) enable reliable connection to battery terminals and load wires.

Board Material: High-grade FR-4 glass-reinforced epoxy PCB equipped with a single power MOSFET and protection control IC.

Technical Specifications:

Series Configuration: 1S (1 Cell, 3.7V nominal / 4.2V max charge).

MOSFET Count: 1MOS.

Continuous Discharge Current: Up to 2A.

Board Color: Green PCB.

Usage Advice: Solder battery connections carefully, ensuring correct polarity (B+ and B-) before attaching output load leads (P+ and P-).

Maintenance: Keep the board clean, dry, and stored in antistatic packaging prior to final pack assembly.

Essential Ultra-Compact 1S Safeguard: Position as a reliable protection choice for low-power single-cell builds such as IoT sensors, wireless microcontrollers, Bluetooth headsets, and small LED indicators.

Highlight Compact 1MOS Efficiency: Emphasize how the single MOSFET design delivers minimal current draw and space efficiency for low-power handheld gadgets.
