I was sent some more interesting cells to test. One type is basically nothing special, but a pair of high-current tabless cells really caught my interest. I definitely haven't had anything like these before, so I think this will be useful.

We recently received several test samples from one of the factories. They were originally designed to be sealed, but we asked them to send the units without potting compound so we could test them “bare” and take a look inside.

This is the third part of my review of various batteries. Today we're looking at completely different cells: a different size, manufacturer, and chemistry. But in my opinion, cells like these are just as much in demand today as the ones covered previously.
