The cells came out of medical devices and because medical devices MUST function at a higher standard, the battery packs are cycled through to prevent any type of problem before it is a problem. We go through each pack and remove the spot welds, and clean as much as we can of the special caulking that is used in medical packs. We are not always able to remove all of it because the caulking can damage the sleeves. Some of the sleeves are the light green sleeves that are only temporary and some have been re-sleeved by us, but rest assured they are the brands listed in the description.

Therefore we are including 100 Dark Blue sleeves with each purchase FREE of charge so that you may have a uniformed look to your build!

These genuine cells are packaged in custom double walled boxes with each cell in its own space protected from all the other cells during transport.

Our owner is also a DIY powerwall builder and wants to share the vast number of cells he has with other DIY’ers at prices only large companies get on volume purchases.  These low prices enables the DIY’er to get the quality product they need to finish their project in a timely manner!
