The Cell Check w/ Low Voltage Alarm is a great multifunctional tool for up to 8-Cell (8S) lithium batteries.

You can use it as a normal voltage tester by plugging it in to a lithium battery’s balance plug. It will provide a readout of each cell’s voltage as well as the total voltage of whole pack.

It can also be attached to your vehicle or aircraft and used as a low voltage safety alert. Simply plug the balance plug into the Cell Check. When a cell’s voltage dips below the preset voltage threshold, the onboard Red LED Light will flash and the Alarm Buzzers will sound. The voltage threshold can be turned OFF or set to a range from 2.7V to 3.8V using the push-button located on the end of the unit. The unit comes preset to a 3.3V threshold.
