It's easy to add up to 6 batteries to an expandable 6 battery server rack with the wires and correctly rated busbar (600amp for 6 ea 100 amp lifepo4 batteries).

This guy explains how to do what your asking better than I can. https://m.youtube.com/watch?v=p0A_zzMPU_w&ra=m

Sorry. The N100 is just too powerful for this. Look into Tesla Megapacks.

What's a common use case for this?

It seems too small to do much on its own, so multiple ones will need to get lined up. So rack mount seems preferable.

A separate inverter needs to be wall mounted.

5kw might cover a small house.

So mainly for off grid small buildings? Or limited backup power? Or maybe a small personal electric car charging station?

No. It states it's an inside unit. "Do not expose the battery to direct sunlight, rain and snow."

It has a rating for light sprinkling of water like an accident, but it not designed for exposure to the outside elements. Also, it requires ventilation, so you can't just enclose it in a large NEMA rated box for protection from the elements as it would prevent proper ventilation.

Yeah, I could see myself using this in my shed that has no power to it with a 3000w charger/inverter and 1000w of solar. Would let me use a small window unit in there if I wanted, as well as basic lights and such.
Easier to mount that a server rack battery for something like that IMO.

Gemini comments = You are very likely looking at a high-risk listing from an unverified seller, and you will almost certainly receive a knockoff, a severely under-capacity battery, or a completely different item.
Seller is ECO-WORTHY, which is an AliExpress Brand+ rated store. ECO-WORTHY cares about their reputation, so they sell good quality products.
