DESCRIPTION Acompact, single-cell lithium battery charging module. Powered by the CN3065 management chip, it safely charges 3.7V Li-ion or LiPo batteries using either a solar panel or a standard Micro-USB cable. FEATURES Dual Input: Features a dedicated solar input (4.4V - 6V) and a Micro-USB port for charging from a wall adapter or power bank. Maximum Output: Delivers a continuous charge current of up to 500mA. Status LEDs: Built-in LEDs indicate battery status (Red: Charging, Green: Fully charged). Easy Connections: Uses standard 2-pin JST or PH2.0 connectors for simple plug-and-play. Safety & Efficiency: Includes short circuit protection and automatic recharging.   APPLICATION DIY Outdoor Gear: Ideal for creating custom solar-powered USB chargers, camping lights, and portable weather stations. IoT & Arduino Projects: Provides a stable power-harvesting solution for remote environmental sensors, trail cameras, and off-grid electronics. Emergency Battery Banks: Keeps small, 1S (3.7V) lithium-polymer batteries topped up when hiking or off the grid.
