CN3065 500mA Mini Solar Lithium Battery Charger Board

Dedicated Solar Li-Po/Li-Ion Charging: Built around the CN3065 single-cell lithium-ion battery management IC, specifically designed to handle unstable photovoltaic solar panel outputs with internal constant-current / constant-voltage (CC/CV) control.

500mA Max Output Charging Current: Delivers up to 500mA continuous charge current, maximizing energy conversion speed for single-cell (3.7V) 18650 cells or LiPo batteries.

JST-PH 2.0mm Connection Ports: Equipped with standard 2-pin JST-PH 2.0mm connectors for seamless plug-and-play wiring to solar panels, lithium batteries, and external loads.

Automatic Low-Power Sleep Mode: Automatically enters ultra-low power sleep mode when solar panel input voltage falls below battery voltage, preventing reverse battery leakage.

Dual LED Status Indicators: Onboard surface-mount LEDs provide instant visual feedback on power and charge status (red LED active during charging, green/blue LED when full).

Thermal Regulated Power Management: Built-in thermal feedback mechanism automatically adjusts charging current under high operating ambient temperatures to prevent overheating.

Housing & PCB Style: High-density FR-4 glass epoxy PCB with blue soldermask and surface-mount components.

Contact & Terminal Style: Standard JST-PH 2.0mm male connector ports and direct solder pads for custom wire harnesses.

Technical Specifications:

Main Controller IC: CN3065.

Input Solar Panel Voltage: 4.4V–6.0V DC.

Target Battery Chemistry: 3.7V Nominal Single-Cell LiPo / Li-Ion (4.2V full charge).

Max Charge Current: 500mA.

Color: Blue PCB with white connector sockets.

Usage Advice: Ensure solar panel output voltage does not exceed 6V DC to avoid damaging the CN3065 chip. Pay close attention to polarity (+ and -) on JST connectors.

Maintenance: Keep board contacts clean, dry, and free of dirt or solder flux. Store in an anti-static bag when not integrated into an outdoor housing.

Essential Solar Energy Harvesting Hub: Position as the go-to power management board for off-grid IoT sensors, remote environmental telemetry stations, solar-powered weather monitoring nodes, and outdoor robotics projects.

Highlight Plug-and-Play JST & Photovoltaic Efficiency: Emphasize the ease of JST 2.0mm connections paired with specialized solar tracking logic that prevents cell drain during night cycles.

Recommended Cross-Sell Add-ons: Pair with CN3791 6V Mini Solar Lithium Battery Charger Board, CN3791 9V Mini Solar Lithium Battery Charger Board, TP4056 1A lithium charging module Type-C, and ESD antistatic mat 50x40CM PCB Welding Mat.
