Pcs Lithium Battery Low Voltage Alarm with Audible and Visual Buzzer for 2S 3S - Real-Time Detection

Welcome to our shop! This low-voltage warning device for lithium batteries is an essential accessory for any modeler concerned about the health of their batteries. Made from PCBs, it is both robust and lightweight. It monitors the discharge voltage of each cell in your LiPo battery in real time. As soon as a cell's voltage drops below 3.0V, the device triggers an audible and flashing light alert—a double reminder that's impossible to miss. This proactive monitoring allows you to recharge or replace your batteries in time, thus preventing over-discharge. It's the best way to protect and extend the lifespan of your battery packs. Thanks to the use of precise integrated circuits and surface-mount components (SMD), this warning device is remarkably compact and lightweight. It installs without adding any significant weight to all your model airplanes, land vehicles, or boats. Perfectly compatible, it works with all 2S (2-cell) to 3S (3-cell) lithium battery packs. You will receive a set of 5 low-voltage warning lights for lithium batteries.
