Racing Drone Multifunction 3-4S LiPo Battery Protection Board with LED Lights and Low Voltage Alarm

This is a multifunctional battery protection board designed for racing drones. It's designed to sit over your LiPo Battery to provide it with a protective shell. In addition, it has functions such as voltage monitoring, low voltage alarm, LED navigation lights, and an active out of control alarm.

Battery voltage monitor: Display the battery real-time total voltage through a digital display.

Low voltage alarm: The voltage alarm can be set so that when a cell reaches the preset alarm voltage (3.3-3.7V), the buzzer starts to alarm and the LED lights start to flash.

Multicolour LED navigation lights: The board incorporates LEDs on top and at the rear with seven different colour options to select from.

Active out of control alarm function: When the battery board is powered on, it starts counting and the buzzer will start to beep in 6 minutes - a useful feature to help you find your quad if you lose it in long grass.

Features:

• Plug and Play - Powered by a 4S or 3S LiPo Battery Balance Plug
• Multicolour LED Lights
• Battery Voltage Monitor
• Low Voltage Alarm
• 6 Minute Buzzer

Please Note: The device is powered by a 4S or 3S LiPo battery's balance plug. Default factory setting is for a 4S LiPo battery. If a 3S LiPo battery is used, the positive wire should be soldered to the pad marked as “3S+” on PCB.
