CC 75/150/500 is a high precision Coulomb Counter (capacity tester) device for monitoring the voltage (V), capacity (Ah), power (W) and energy of a battery. These information allow user to get a precise State of Charge in % (SoC) and Depth of Discharge (DoD) of the battery. It also calculates in real time remaining time before battery gets fully empty.

More information regarding SoC calculation for Lithium batteries

CC device has a memory feature to save SoC information when the device is powered off or accidentally disconnected.

CC 75/150/500 are suitable for lithium iron Phosphate (LiFePO4), Lithium ion and Li-Polymer batteries, lead acid and nickel metal hybrid batteries with a working voltage from 8V to 80V DC.

CC device exists in 3 versions:

  • CC75, measurement from 0 to 75A, compatible with M6 terminals
  • CC150, measurement from 0 to 150A, compatible with M8 terminals
  • CC500, measurement from 0 to 500A, compatible with M10 terminals

For each CC model, there is a choice of 3 lengths for shield wire between shunt sensor (sampler) and display, depending of the location of your battery and monitoring display :

  • 1 meter
  • 3 meters
  • 5 meters


Connection is done by using 2 wires (provided):

  • Shield wire will connect display to the precision resistance (sampler). This wire will be plugged with 5 pole connectors on both sampler and display.
  • Low power wire (0.3 – 0.75mm2) to connect sampler to battery positive pole (red). This wire will be connected on one of the 2 poles of the connector located on the sampler (marked B+). The other end of this wire needs to be connected on the battery positive pole.

As a first operation, cut a rectangular hole and 2 screw holes on the panel of the equipment. Then install CC 75/150/500 display inside the aperture from the back of the display shell. Use two 2mm screw to maintain the display.


In order to keep LCD display operation for a long time :

  • Do not expose CC75/150/500 display to direct sun light for a long time
  • Do not use CC75/150/500 at low temperature (60°C)
