These would be great for DIY battery box builds. Two of them would only take less than a 11" x 11" x 9" volume. Also very light.

Wonder how they achieved a 18% increase in energy density. ?

Was wondering that myself. Maybe just more focus on packaging, and it's "only" a 100A BMS.

@Will Prowse Maybe Will can dissect one for us

Well this battery just disappeared from Amazon for some reason.

It is on Amazon as of right now and has a 4.7 review rating.
There are a few other brands now offering mini versions as well.
They are appearently based on some new tech. Here's one article I found in a quick search.

The mini batteries are ALL pouch cells, not solid prismatic cells, personally I would avoid them, but if you have them, only charge to 90-95%

Good to know how these are different. I'm running two powerqueen 12v 200ah, in our studio shed, and a 12v 100ah in my mobile generator. They have been performing flawlessly for over a year. I was definitely interested in these.
