SAMSUNG ICR18650-26F CELLS IN MODEM BATTERIES! You get 2 cells in a pack for just $1.50! 75 CENTS PER CELL! Comes to just $80/kWh!
These are a great source of genuine Samsung 2600mah cells! We spot tested thousands of these cells and they came out around full capacity! You can pry the seam with a pair of wire cutters to get the cells out.
Since these have been in storage uncharged for shipping standards it's possible some will have low voltage, but they will wake up for sure. Out of thousands we have tested there were only a few bad cells.
