LIPO BATTERY ALARM & VOLTAGE CHECKER Specifications Battery range : 2S-6S LiPO Voltage display resolution : 0.001V Voltage Detection precision : 0.005V Cell Voltage display range : 1.50 - 4.99V Total Voltage display range : 3.00 - 29.94V Alarm cell voltage : 2.00 - 4.00V Current loading of test : 8mA Pins distance : 2.54mm OR 2.00mm Size : 87x25x12(L*W*T,mm) Weight : 20g Package : transparent heat shrink tube Summary Accurate and easy to use, the CellMeter-6 is a microprocessor controlled high precise voltage detector, the unit can measure each cell voltage in 2S-6S LiPO/LiFe/LiIO battery pack, the total voltage and voltage difference are displayed simultaneously. Especially, CellMeter-6 will give a warning buzzer/LED when any cell voltage reaches any value you set in flight, or over 4.22V in charge. The unit includes reverse polarity detection, and 2.54 or 2.0mm pin distance balance connector for all kinds of battery. In flight, CellMeter-6 can alarm when any cell voltage under setup value, before flight please press the button set up the lowest cell voltage and press for 3 seconds confirm.
