Vacuum Battery Modules with 8x 2100mah 18650 Cells

These modules were recovered from vacuum cleaners. Each module has 8 18650 cells inside. Sanyo UR18650A. Great cells for the price. You could also test the batteries and sell them on eBay for around $30 for the ones that still work. We just don't have the time. Selling them for cell recovery untested.

Cells are in 4s2p configuration. The BMS likely only works with the vacuum. We opened a few packs the cells were resting around 2v or so. None of them were fully discharged. These should be a good source for cell recovery and I'm sure some of the packs will work still but you may need the actual vacuum to test the packs and confirm they work in the vacuum.
