CAN Power Module - M10104 
The sensor is based on the ACS37800 power monitoring IC, which provides 0.85 mΩ primary conductor resistance for low power loss and high inrush current capabilities. It has excellent accuracy over the entire range: 0-60A continuous.
The integrated capacitors reduce voltage noise, however we still recommend to install the included electrolytic capacitor to compensate for long battery wire lengths and motor noise.

WARNING
Important! The module comes with pre-calibrated values, however end users are encouraged to verify and tune constants provided in the module's paramaters.BATT_V_FINE_M and BATT_C_FINE_M are multipliers set to 1.0 by default to fine tune your power readings. Keep a safe margin of battery capacity for your tests until verified .
The board comes with jumpers which may allow for I2C instead of CAN connectivity, however neither PX4 or Ardupilot provide drivers at the moment.
