1S 3.7V Lithium-Ion Battery Capacity Indicator Module
Order before 12.00PM
This compact battery level indicator module is designed to visually display the charge level of multi-cell battery packs using a segmented LED bar. It is particularly well-suited for 1S (3.7V) lithium-ion battery.
The module features a red outline to indicate the battery shape and green LED segments that progressively light up based on the current battery voltage. It is ideal for portable electronics, battery-powered tools, and DIY energy storage systems where quick visual feedback of battery charge status is needed.
Features:
-
Battery Compatibility: Lithium-ion, Lead-Acid, and NiMH battery packs
- Voltage Thresholds: Segment activation based on nominal cell voltage
-
Visual Display: Red battery outline with green LED level indicators
-
Compact Size: Easily mounts onto enclosures or dashboards
-
Low Power Consumption: Efficient voltage detection without high drain
