In this video, we do the initial boot and configuration of the JK BMS. We also try yet another flexible bus bar option, the "LithiumSolar Loop". We test the resistance of the rigid bus bar and the three types of flexible bus bars we've made and, finally, make a decision on what flexible bus bar to use.

This is the last video of the year, so happy new year, happy solstice, merry Christmas, happy Chanukah, and if you celebrate any other holiday, I wish you the best for that as well. See you in 2022!

Very much rough and in-progress spreadsheet on the JK BMS config (Sheet 2) and the data from my battery (Sheet 1);
