Harnessing solar power to charge lithium-ion batteries is not only energy-efficient but also an eco-conscious choice for portable electronics. In this article, we explore a compact and reliable lithium-ion solar charger circuit that uses a few standard ICs: LM2941, LM3420-8.4, and LMC662. Designed for charging a 2-cell Li-ion battery pack, this setup is ideal for […]
