NEW PANASONIC 2270MAH NCA103450 WITH WRAPPER
Here are NEW Panasonic NCA103450 lithium ion cells. These are awesome cells and perfect for a variety of applications.
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.
