Battery Monitors

Introduction

A range of baragraph type LED voltage indicators that sequentially light up a series of LED's as the voltage changes. Also our receiver battery load tester.

3 LED Voltmeter 12V - Part No: 1061-001
4QD's Battery Condition Meters circuitry is unique to 4QD and was originally designed for an audio decibel metering circuit on a professional audio mixing desk - it is very accurate, yet the circuitry is so simple that our LED meters are about the most economical available.

The circuit uses LEDs (Light Emitting Last) to give a 'line of light' type display which extinguishes from the top as the battery is discharged. In most applications it is connected to the battery via an ignition switch so that it extinguishes when the machine is turned off. It is currently available in four standard versions.
