The Universal Battery Level Indicator is a compact, ultra-thin LED module used to monitor the real-time capacity of 18650 Lithium-ion, LiPo, or Lead-acid batteries.
Quick Highlights
Visual Display: Uses 5 LEDs to show power levels (20%, 40%, 60%, 80%, 100%).
Energy Efficient: Features a “TEST” button that activates the LEDs only when pressed; it auto-shuts off after 3–10 seconds to prevent battery drain.
Plug & Play: Simple 2-wire connection (Red to Positive, Black to Negative).
Durable Design: Includes reverse polarity protection to prevent damage if wired incorrectly.
Versatile: Compatible with voltages ranging from DC 3V to 34V (depending on the specific cell configuration selected).
