Battery Charge Level Indicator DC 12V / 24V / 36V / 48V / 60V / 72V LED Voltmeter Tester

The Battery Charge Level Indicator LED Tester is a compact and versatile module designed to monitor battery voltage and display real-time charge levels across multiple voltage systems. Commonly used in electric vehicles, solar systems, and DIY battery packs, this module provides a simple and effective way to visualize battery health and remaining capacity.

These testers typically support a wide voltage range from 12V up to 72V (and sometimes even higher), making them compatible with various battery types including lithium-ion, lead-acid, LiPo, and NiMH batteries.

The module combines a digital voltmeter with an LED bar indicator. The LED display usually consists of 8 segments (2 red + 6 green), showing battery levels from empty to full in percentage steps, while the digital display shows the exact voltage reading for more accurate monitoring.

Designed for ease of use, it only requires simple two-wire connection (positive and negative), making installation quick and suitable for both beginners and professionals.
