This Battery V Checker is used to detect 1S ~ 8S lithium batteries, and automatically detect the voltage of each cell lithium battery and total voltage. Supports reverse connection protection. It allows you to work anywhere in the understanding of the state of your battery, so your battery will not overcharge and discharge or cause damage. When the voltage drops below the set value, the buzzer sounds the red LED flashes; the factory default setting is 3.3V, press the button to change the voltage setting, and automatically save the user's current settings.
