New Case of 108 Panasonic NCR18650A 2900mah cells
Just 92 cents per cell for never cycled 2900mah Panasonic cells. This comes out to just $86/kWh for packs that have never been cycled. All the manufacture dates on the boxes we checked were 07/2020. They were just overstock and stored in a temperature controlled environment.
We tested thousands of these cells and they all tested between 2970-3010mah so you can expect these cells to test like new.
Here are new, unopened cases of medical batteries. Each case has 12 battery modules. Each module has 9 Panasonic NCR18650A 2900mah cells in 3s3p configuration. You will get a total of 108 cells for this price. You will have to crack open the modules to get the cells out. You can keep the cells in the 3s3p configuration and just solder to the BMS tabs inside or break all packs down to cell level. Since DOT requires lithium batteries to be shipped at a lower state of charge most of these cells will be sitting around 2.8v.
The last 2 photos show how we opened the ones we tested. We scraped a small slit on the seam in the corner, not too deep because the cells are right there. Then we used a plastic scraper tool and pushed it on an angle to avoid hitting the cells, Then we slid the scraper tool down the seam. It's very easy when you get the hang of it. Just do not hit or damage the cells.
