Simple to use Lipoly low voltage alarm that is small and light weight for on board use. This unit has leads that can be connected directly to your power source and monitors the overall voltage. The LED will change from blue to red (solid lit) and the buzzer will make a low pitched sound when the battery has dropped to around 3.4V/cell. The LED will flash red and the buzzer will make a high pitched sound when the battery has dropped to around 3.2V/cell. At this time, you will need to stop using the battery immediately to prevent over-discharge.

Features:
• Reverse polarity protection
• Embedded microcontroller
• Jumper setting for selection of input voltage (LiPo 3~8 cells)
• Low power consumption: approximately 40mA
• LED and buzzer alarm indicators
