How To Use
If the Input voltage is under 5v, no display on the LCD
If the Input voltage is above 27V,the BB6L will be hurt
1.Connet the LiPo balance adapter to the Pins of BB6L
If the polarity is recersed.no display on the LCD screen
If the Lipo pack is below 6 cells,pls connect the balance adapter from the cathode(-)side
After the BB6L detect right input ,LCD screen will show the total voltage (Total V),unit voltage difference(--mV)to cycle automatically
Press the button to show the voltage values manually
Because of the time diffrence of connection between Pins & LiPo balance socket,Maybe the voltage value of first cycle is not correct.It will be correct.It willbe correct from the 2nd cycle.
2.Set the Alarm values
Hold the button 3 seconds to enter the setting 
Alarm voltage can be set between 2.7V~4.0V/cell in 0.1V increments by pressing the button,Alarm function can also be set as OFF. Default is 3.3V
The value will be saved & exit if no action within 5 seconds
3.Low voltage alarm & The lowest cell voltage 
During the using of LiPo ,BB6L will detect the voltage always 
If the cell voltage is below Alarm value, the alarm will be triggered with "Be..Be..Be.."and the lowest cell voltage will be falshed
If the alarm be triggered,the alarm value still can be set by holding the button 3 seconds
If the cells voltage rise again, the alarm will be suspended,and the lowest cell voltage still be shown 
Press the button to show total voltage unit voltage difference & the lowest cell voltage to cycle manually 

Package includes:
1 x LiPo Cell Checker & Low Voltage Alarm
