  After lots of research I found software called CANHacker which uses an Arduino and a MCP2515 CAN adapter to display the CAN signals in your car.
  Please read below BEFORE asking questions.
  Thanks
  
  The CANHacker software is available here.
  https://www.mictronics.de/
  Click on "Archive" and scroll down, click on "USB-CAN Bus Interface" and download it.
  NOTE! If the link comes up as "Forbidden" try copying and pasting the URL into your browser or Google mictronics.
  
  The sketch for it is here
  https://github.com/autowp/can-usb
  
  Libraries and connection diagrams for it are here
  https://github.com/autowp/arduino-mcp...
  https://github.com/autowp/arduino-can...
  
  After installing the libraries you may have to edit the canhacker.h file to match the clock speed of your MCP2515 adapter. Mine is an 8Mhz adapter and the default is 16Mhz.
  
  If you bought a Nano from eBay you may need to select Nano then select ATmega328P(Old Bootloader) to get the sketch to upload.
  
  If you get nothing on the CANHacker software
  1. Double check you are using the correct CANbus speed for your car.
  2. Check the baud rate of the Serial port is correct.
  3. Check in the settings that "Listen Only" is unticked.

  18650 Cells
  If you are looking for 18650 cells to build a battery pack here is where I buy mine. I have always used LiitoKala cells and found them to be good quality.
  Note the Name brand cells are copies, they are NOT genuine but do have similar properties to the original and are still excellent batteries.
