## Description

Quickly monitor the status of 1S-8S lithium battery packs, display the voltage on each cell or total and warn you with a buzzer when discharging. The low voltage threshold is adjustable from the button, and below 3.3V the LEDs flash and the alarm sounds. Works with Li-Po, Li-Ion and Li-Fe, is powered directly from the battery and measures up to 36V.
Battery tester for lithium cells from 1S to 8S. This module detects the individual voltage of each cell or the complete assembly, offering in addition to displaying the respective voltage and the acoustic alarm function. It helps you to know the status of your batteries at any time and to detect possible overcharging or overdischarging of the cells.
When the voltage drops below the set value of 3.3V, the LEDs flash and the alarm sounds. The default low voltage value can be changed by pressing the button on the tester.
The device supports any lithium-based battery with a nominal voltage of 3.7V (Li-Po, Li-Ion and Li-Fe) and is powered directly from the measured battery.
