The 1S to 8S Battery Level Indicator Module is a compact and efficient display board designed to visually monitor the voltage level of lithium battery packs ranging from 1 cell (1S) to 8 cells (8S) in series. Equipped with a bright LED bar display, it provides an instant and accurate representation of battery charge status, making it ideal for DIY battery packs, e-bikes, solar storage systems, and RC projects. Its plug-and-play design allows quick connection directly to the battery’s balance port or main terminals for real-time voltage indication.
