The Chargery Battery Saver BM12 is the first up to 12S LiPo & LiFe battery saver with a full TFT color LCD. A bright red LED and two loud beepers (95Db) make sure of your flight safety. Warning voltage, delay time and warning time can be established by pressing a button. The large TFT color LCD display can display each cell's voltage from 2S-12S. During flight, the BM12 can sound warning or LED warning if any cell voltage reaches a user defined preset to prevent a over discharge. The Bm12 will also record the lowest cell voltage during flight which can be checked after the flight is completed. During charging, the BM12 will monitor the cells voltages and if any cell reaches 4.22V or over, sound the alarm. Features: The BM12 will record the lowest voltage of any cell, including the total pack voltage during flight. After the flight is completed, the UP button can be pressed to display the recorded low voltage cells. Pressing the DOWN button will display current cell voltages. An auto off function will engage after 2 minutes to save battery power. At any time, you can press any button resume display. Specifications:
