101 INC - 101 Inc. Li-Po Warning Buzzer

This little helper is a very useful tool when it comes to checking your Li-Po batteries for harmful undervoltage. To do this, the Li-Po Warning Buzzer is plugged into the balancer connection of the battery, whereupon a certain voltage is shown on the mini display. Depending on the cell and charge level, the buzzer then warns of an existing or impending undervoltage, which makes it necessary to charge the battery.
Useful (of course?) you can also connect the Li-Po Warner to the battery during the airsoft game in order to be able to regularly check the battery performance. This can effectively protect against permanent damage to the battery cells and increase the longevity of your batteries enormously.
