The beginning of my powerwall
#1
Hello, I am posting this so that I have evidence to my cell count, so far I have just shy of five thousand. I started collecting laptop batteries a few months ago, and have been looking forward to setting up and running my own powerwall. I am currently in the process of closing on a new home and I can't wait to start getting my powerwall setup A.S.A.P. I work two IT jobs which grants me access to a ton of 18650's. I will post a few pictures of my progress so far, and keep it updated as things progress.



This picture is of my tested and cleaned cells, I will be using the orange cells as my exterior. My packs will consist of 120 cells, all the cells upon the desk are above 2000 mAh.


Here is my pile of soon to be cleaned cells, they have been tested as good, but they have not been tested for capacity.


Another box of my exterior cells.


My first attempt at some packs, was looking at 100 cells a pack but decided on 120, I also realized I had way more orange cells than green.  Undecided

What do you use the trowel for?

Thanks,

I use the trowel to clean the hard glue off of my cells, that was just a hard flat tool that was in reach, I was usually using a letter opener. I can post a picture of my process. Big Grin

I would love to know more about your process!  Given the number of cells you have processed, you must have a few tricks you have figured out.

Thanks,
