  • BCM16ELP can indicate battery SOC or called battery gauge similar with car dashboard. Cell count, battery pack voltage and battery gauge (%) is displayed simultaneously.
  • BCM16ELP will record the lowest voltage of each cell during discharge, after you stop driving your bike, scooter etc., you can press UP or DOWN button to display these voltages (cell number background color is green, and the lowest cell voltage displayed in RED text), press the button again display real voltage.
  • Add an alarm port to drive relay etc.
  • Beeper sound and LED flash alarm alternately while any cell over charged or over discharged or out of the setup range including temperature SOC, difference of cell voltage.
  • Two temperature sensors monitor battery temperature during charge or discharge.
  • At any time, you can press SET button shortly turn off the display and press again resume.
  • While alarming, press SET button shortly turn off alarm.
