2S Li-Battery Boost Charge Module

Key Features

• Supports 2-Series Lithium Batteries: Works with 7.4V (nominal) Li-ion or Li-Po packs.

• Integrated Charging Circuit: Automatically manages safe charging and balancing of both cells.

• Built-in Battery Protection: Over-charge, over-discharge, over-current, and short-circuit protection.

• High-Efficiency Boost Converter: Steps up battery output to a stable higher voltage (commonly 9V, 12V, or 5V depending on model).

• Multiple Output Options: Some versions include USB output or 5V/12V regulated outputs.

• Compact & Lightweight: Perfect for embedding into battery-powered projects.

• Plug-and-Play: Requires minimal external components.

🧠 How It Works

The module manages your two-cell lithium battery pack by:

1. Charging both cells evenly to ensure safety and long life.

2. Monitoring voltage to prevent over-charging or over-discharging.

3. Boosting the battery output to a regulated, stable voltage suitable for your device.

This makes it a complete power solution for any electronic project that needs a reliable 2S battery setup.
