LiPo Battery Cell Checker Tester with Low Voltage Alarm for 1-8S Batteries

A two in one tool that gives a loud alarm (try alittle hot glue to lower loudness if too loud) warning of low voltage and can also display battery voltage. Plug a 1-8s battery’s balance connector into the device, and you will receive an instant readout of the total voltage as well as an individual reading of each cell.  A must have on hand while flying!
