4S Lithium Battery Capacity LED Indicator

• 1.Intelligent electricity quantity display board;slightly push trigger switch,it will auto power off after 3 seconds display
• 2.Static power consumption 2.3MA,and it can be disregarded
• 3.Plug-in indicator light color:25% red,other 3 pcs are green
• 4.Application Fields:battery electricity quantity detecting;only needs to connect seperately battery's positive and negative with electricity quantity board's positive and negative;slightly push trigger switch,then it can be able to detect current electricity quantity.4 LEDs will divide battery comprehensive capacity into 4 phases;slightly push the switch,electricity quantity will be shown
