Battery Module with 4x Sanyo 2250mah 18650 Cells

Specs for the cells are in the 2nd photo. For $2 you get a battery module as shown with 4x Sanyo 2250mah cells in 2s2p configuration. These are perfect for salvaging the cells and using the scrap circuit board and wire for metal recovery. There is some nice gold on the PCB for those who get gold off circuit boards.
