NEW PANASONIC 2270MAH NCA103450 NO WRAPPER
Here are new Panasonic NCA103450 lithium ion cells. These are awesome cells and perfect for a variety of applications. The cells in particular don't have shrink wrap on them. You can use kapton tape, shrink wrap, etc. Or if you build them into parallel packs you don't need the wrapper at all. 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.
