This third entry about the build a DIY Powerwall, we are going to make the first battery pack assembly. As we discussed above, we will use 18650 Chinese (aliexpress) cells, Liitokala’s NCR18650B cells.
In this new entry I will present to you one of my last creations. It is a DIY load cycles tester for 18650 cells. And you’ll wonder, what’s that for?
In this entry we will try to explain how you can weld 18650 batteries with tin very simple and quickly.
