What is the difference between Tesla Battery and Winston Battery products?

From technical point of view, the Tesla battery technology is based on thousands of small cells being integrated into modules and battery packs. Tesla is deploying the li-on based chemistry using the Panasonic consumer type cells.  On the opposite Winston Battery is using large capacity cells of industrial design based on the lithium iron technology (LiFePO4). 

There are no small cells inside the Winston Battery product. A single cell is a single cell - full stop - no jigsaw puzzles.
