Description

The Five-Level Lithium Battery Level Indicator is a compact, press-to-test diagnostic module designed to provide quick and reliable capacity monitoring for LiPo and lithium battery packs. Featuring a clear five-level LED display and a tactile red push button, this indicator allows you to check your battery’s charge and discharge state on demand simply by pressing and holding the button.

Engineered with built-in reverse polarity protection, the module safely prevents circuit damage if the wires are accidentally mismatched during installation. Equipped with a 140mm connection cable and an ultra-slim profile, it is an ideal portable power monitoring accessory for DIY electronics, custom battery boxes, and mobile projects.

Note: The module draws approximately 300mA only while the push button is actively held down; releasing the button immediately powers off the unit to conserve energy. Package includes 1 indicator board with integrated cable.


Key Features

  • On-Demand Push-Button Activation: Press and hold the integrated red push button to check power levels; automatically powers off when released.
  • Five-Level LED Voltage Display: Clear multi-stage LED array maps directly to specific voltage thresholds (L1: 9.6V, L2: 10.2V, L3: 10.8V, L4: 12.6V, plus full tier status).
  • Reverse Polarity Protection: Smart internal circuit design safeguards the board against accidental reverse-wiring during hookup.
  • Pre-Wired Lead Harness: Includes a convenient 140mm connection cable for fast and flexible wiring to your battery terminals.
  • Ultra-Compact Profile: Slim circuit board design (approx. 62 × 16 × 2.7 mm) fits easily into tight enclosures and custom faceplates.

Benefits

  • Instant Power Checks: Quickly evaluate your battery pack’s operational status without dragging out a digital multimeter.
  • Zero Standby Drain: Because power is only drawn while the button is pressed, the module creates zero parasitic battery drain during normal storage.
  • Safe & Foolproof Setup: Reverse connection protection prevents accidental burnout during hobbyist installation.

Applications

  • LiPo Battery Packs: State-of-charge monitoring for custom RC, drone, and portable LiPo power assemblies.
  • DIY Power Banks & Enclosures: Add a quick-check voltage gauge to custom portable electronics and battery boxes.
  • Maker & Prototyping Projects: Compact voltage monitoring tool for breadboards and experimental DC rigs.

Package Includes

  • 1 x Five-Level Lithium Battery Level Indicator Board (with 140mm cable)
  • 1 x Instruction Manual / Quick Guide
