About this item
This voltage display is used for 1S~8S lithium battery detection, and automatically detects the voltage and total voltage of each cell of the lithium battery. Support reverse connection protection.
It allows you to know the working status of your battery anytime and anywhere, so that the battery will not be damaged by over-discharge or over-charge
Whether it is in flight or in idle state, you can plug the electric display into the battery balance charging connector to understand the battery power status. It is a must if there is no multimeter!
When the voltage is lower than the set value, the buzzer will sound and the red LED light will flash; the factory default setting is 3.3V, press the button to change the voltage setting and automatically save the user's current setting.
