1S-8S Li-ion Battery Level Indicator Module

The 1S-8S Li-ion Battery Level Indicator Module is a standalone green LED bar graph display that shows the remaining charge level of a Li-ion or LiPo battery pack from 1 cell (1S) to 8 cells in series (8S) using four green LED bars — where all four bars lit indicates a full charge and one bar indicates a low battery — without requiring any microcontroller, Arduino, or external power circuit, connecting directly across the battery terminals and drawing only 5mA of operating current so it does not meaningfully drain the battery being monitored. The Battery Level Indicator Module preset is configured for 1 cell at the factory and the cell count is adjusted to match the actual battery pack (1S through 8S) before use.

The li ion battery indicator accepts input voltages from 12V to 60V across its operating range, covering common multi-cell LiPo and Li-ion pack voltages used in drones, e-bikes, RC vehicles, solar storage systems, and portable power banks. The 4-bar green LED display gives an instant visual read of charge state — full, three-quarter, half, or low — without needing to read a number or interpret a voltage value, making the 1s to 8s battery level indicator module useful for quick pre-flight or pre-use battery checks. Available from StemVolt. This battery level indicator price-accessible module is ideal for LiPo drone RC e-bike solar pack and STEM project Li-ion battery monitoring display.
