The voltage checker is used for 1S~8S Lithium battery detection, it automatically detects the voltage of each cell and total voltage of a battery pack. Supports wrong polarity protection.

It allows you to know the working status of your battery anytime and anywhere, so that your battery will not be damaged by over-discharge or over-charge.

When the voltage is lower than the set value, the buzzer will sound and the red LED will flash; the factory default setting is 3.3V. Press the button to change the voltage setting value, the user's current setting value will be saved automatically.
