Mini Solar LiPo Battery USB Charger Board CN3065 Module

Mini Solar LiPo Charger Board – CN3065 Module

Power your lithium polymer battery projects with clean, renewable solar energy. The Mini Solar LiPo Charger Board (CN3065) is a compact, easy-to-use charging module designed to extract maximum power from a solar panel or other photovoltaic source and deliver it safely to a single-cell LiPo (lithium polymer) battery. It also supports USB charging via Micro-USB, giving you a versatile dual-input solution for any DIY electronics project.

Simply connect your solar panel to the input side, attach your LiPo battery, and the board handles the rest — automatically managing charge current and protecting your battery from short circuits. Made in China.

Frequently Asked Questions

Q: What type of battery is compatible with this solar LiPo charger board?

A: This charger board is designed for single-cell lithium polymer (LiPo) batteries. It connects via a standard 2-pin JST / PH2.0 connector. Always ensure your battery capacity matches the 500mA maximum charge current — it is generally recommended not to charge a battery at more than its rated capacity in milliamp-hours (mAh).

Q: Can I use a USB power source instead of a solar panel?

A: Yes! The CN3065 charger board supports dual-input charging. You can use either a solar panel (4.4V–6V DC input) or a standard Micro-USB connection to charge your LiPo battery, making it highly versatile for both outdoor solar projects and indoor USB-powered setups.

Q: How do I know when my battery is fully charged?

A: The board features two built-in LED status indicators. A red LED illuminates while the battery is actively charging. Once the battery reaches full charge, the LED switches to green, giving you a clear, at-a-glance status update without any additional monitoring equipment.

Q: Is short circuit protection included on this module?

A: Yes, the CN3065 module includes built-in short circuit protection to help safeguard both your battery and connected circuitry during charging operations.
