I have about 150 Sony VTC6 18650 cells. I purchased them from EVWest but had to buy 200 at a time. I’ve been holding onto them for future projects but I’m happy to sell them if anyone else would like some. I would sell them for $4.25 each (I’m not making any money on this). I can also include the battery shrink needed for safety. The cells are great quality and have a good balance of both capacity and discharge amps.
I’ve made a few battery packs that include the BMS and specifying chargers as well. I also have a battery spot welder that I’m happy to leave at the space if anyone wants. Please feel free to slack me if you want more details.
