  • High accurancy
  • Two-wires connection: simply connect the red and black wire to positive and negative pole respectively.
  • With reversed connection protection, meaning meter will not burn when connected reversely.
  • 0.36" LED digits visible display; it requires low voltage to start; if volt is less than 3.5V, the LED will dim but not affect measurement.
  • It can test voltage of 18650 or lithium battery, NiMH battery pack, moto, auto, car, etc; screw potentiometer in back side for more accurate results.
