1-8S Lipo Voltage Tester with Buzzer – Low Voltage Indicator

This is a Lipo voltage that can test the voltage of a battery pack as well as a single cell in a battery pack. The module has an onboard buzzer that will indicate if the voltage reaches user defined voltage. The module is a combination of Lipo battery voltage buzzer+indicator, directly plug it into your operating battery, it will monitor the conditions of your battery all the time, so your battery shall remain within safe operating voltage range all the time. 

Feature

• Use for 1-8s Lipo/Li-ion/LiMn/Li-Fe
