Upgrading the BMS

Go to the folder we downloaded (wherever you have downloaded it to) named "Controller Upgrade Tool (for all controllers)".

Inside the folder, click on the "Project 1" application:

When you open the application, this is what is going to show up:

Take your USB CAN Analyzer and cables:

Connect the USB to the computer and the square end to this side of the Can Analyzer, and keep both dip-switches down:

Connect the other cable to the Can 1 port:

The Ethernet cable connects to the COM port on the battery:

In the software, change the following values to the ones showing in the circles:

Product Type: Host

KBP: 500

Host address: 1

Once the progress bar is full and says 100%, it is done.

PLEASE MAKE SURE NOTHING INTERRUPTS THIS PROCESS (no unplugging the cable), BECAUSE IT CAN BRICK THE BMS.
