This is a compact solar LiPo charger based on the CN3065 — a single-cell lithium battery charge management IC. This solar charger enables efficient power transfer from a solar panel or other photovoltaic source to a rechargeable LiPo battery. Setup is simple: connect your solar panel to one side and your battery to the other to begin charging. The charger is designed to charge a single lithium polymer (LiPo) or lithium-ion (Li-ion) cell. The load should be connected in parallel with the battery. Default maximum charge current is 500 mA. Recommended input voltage range is 4.4 V to 6 V. Do not charge batteries at currents exceeding their rated capacity. Color: Blue Material: Polycarbonate + metal Solar panel input voltage: 4.4–6 V Maximum charge current: 500 mA Interface: 2-pin JST connector (or PH2.0) Short-circuit protection Continuous charge current up to 500 mA Battery status indication (Red: Charging, Green: Fully charged) Supports USB charging via Micro-USB connector Dimensions: 2 cm × 4 cm Package includes: 1 × solar charger module Note: Color appearance may vary slightly due to lighting conditions and screen settings. Dimensional tolerance: ±1–3 cm.
