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.

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, open 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)
