This was an excellent experience working with Amy. She always provided timely updates and answered many questions for me along the process. She sent me the link to the cell report which I downloaded and saved locally. She sent me the FedEx tracking label information. She got answers from EVE for me about the QR code decoding. All cells were manufactured in either February or March of 2021 so all were brand new as promised. They arrived boxed very well except for one box had been dropped by the shipper. One corner of one cell had slight damage so I am currently load testing it to make sure it does not have internal damage. I took pictures and posted them to Amy on the Alibaba messenger app, which works very well for communicating with her. There was a short delay in shipping because there were not enough cells in stock for my order.

I am building three 48v batteries with 16 cells in series using an Overkill Solar BMS for each battery (16s). I purchased an additional four cells to have as spares and quite frankly because I wanted to play with them for different projects so, of course, I needed a 12v 4s BMS for these as well. After pre-charging and top-balancing the cells I made my compression cases out of 1/2 inch plywood glued, pin-nailed then counter sunk each corner with two square-head wood screws. I received some unused plexiglass sheets that I cut to size for the top. So far, I have two of the 48v batteries in service with an ANL fuse and quick-disconnect switch on each battery case. I included a couple of pictures for reference. Still have some tasks, like tape down the balance wires and replace my original 2/0 battery cables with more flexible cable from WindyNation (Amazon) to make everything more pretty but they are working well.
Many thanks to Will and so many others with good information and videos and links to pieces and parts needed to make this project a success!
More later.
