High-quality materials, excellent craftsmanship, safe, reliable and durable, Many size and complete specifications, convenient and flexible installation, convenient maintenance and better cost performance.

2 in 1, with two functions: power display and low voltage alarm (low voltage can be adjusted)

This voltage checker is used for 1S-8S lithium battery detection, automatically detects the voltage of each cell and the total voltage of the lithium battery, supports reverse connection protection.

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

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

ATTENTION!!! 
After a long test, we found that 1S 3.7V part of the battery is not effective! It is recommended to use it on top of 2S - 8S batteries !

Product does not include batteries !
