The Solar LiPo Charger is an ultra-efficient, plug-and-play module designed for sustainable energy projects. Engineered to intelligently charge 3.7V LiPo/Li-ion batteries (e.g., 1000mAh packs) from solar panels, it combines industrial-grade durability (-40°C to 85°C operating range), reverse-polarity protection, and automatic voltage cutoff (4.2V ±1%) for safe, maintenance-free operation. With a compact size of 33×33×12mm, it seamlessly integrates into IoT sensors, solar-powered gadgets, and emergency power packs—ideal for eco-conscious makers and engineers 🌞.
