Here new naked Panasonic NCA103450 lithium ion cells. These are awesome cells and perfect for a variety of applications. The cells in particular are "naked" because they don't have shrink wrap or insulators on them. You can use kapton tape, shrink wrap, etc for the shrink and thick masking tape for the insulator. Or if you build them into parallel packs you don't need the wrapper at all but definitely add an insulator. You can simply cut a little square out on tape and wrap around the positive tab so you can't short the positive tab on the negative casing. These were extra cells left over from a huge battery pack assembly project.

Unlike cylindrical cells, these flatter style shapes leave no diamond shaped wasted space in between cells when put into packs. When you build a battery with theses you will have a very energy dense pack.

The 2nd photo shows the spec sheet. You can easily discharge these continuously at 2c which would be a 4.54 amp continuous discharge rate.

These cells still charge up to 4.2v and discharge down to 2.8v like any other lithium ion cell and they can be spot welded. Just remember the whole case is negative except for the positive tab just like 18650 cells.
