Description
The smart battery indicator panel, gently press the trigger switch, and the display will automatically close after 3 seconds.
Static power consumption 2-3 microamp, negligible.
Multiple battery packs are available, such as single,2,3,4, lithium battery packs.
Indicator color:25% red, other 3 green
Size:44 x 9 x 7.5 mm
Application scope
To detect the battery power, just connect the positive/negative electrode of the battery to the positive/negative electrode of the battery indicator board, and gently press the trigger switch to measure the current battery power. The total capacity of the battery is divided into 4 sections by 4 leds. The power level of the battery is known by the flick of a switch.
