8Fields LiPo Battery Alarm with 8S Voltmeter

This is a special electronic device designed for Li-Po batteries. The device is meant to protect both the battery and the user by automatically measuring the voltage and alerting both audibly (via the speaker) and visually (LEDs and display), allowing the user to safely use the battery, avoiding potential over-discharge or in case a cell fails during gameplay to replace the battery.

To activate this device, simply connect it to the Li-Po battery using the charging/balancing connector that the battery is equipped with. The device is equipped with 8 pins, allowing it to function with batteries of up to 8 cells even if the 7.4V battery has only 3 pins; it connects respecting the polarity to only 3 of the 8 pins of the alarm. At the top, the alarm features a button for adjusting the minimum voltage threshold for triggering the alarm. The display shows the voltage of the entire battery as well as each cell of the battery, automatically cycling through all stages during operation.
