139x New Sanyo UF103450PN 3.7v 2000mah Cells

Here you get 139 cells in a box. These cells are new and overstock from a large project. These are actually one of the most energy dense cells since they are smaller. You can spot weld the top bottom and the bottom is all negative just like any other cell. These are a flatter cylindrical cell.

You can discharge these up to 2c (4a).

Just $1/cell

If you have a project that requires a flat profile with a lot of energy density these are hard to beat.
