I believe one of the reasons it is cheap is the BMS doesn't have low temperature (cold) cutoff and isn't a smart Bluetooth BMS. But if you live in a warm climate I wouldn't worry about low temperature cutoff. It looks to me like batteries with outdated BMS's are being cleared out for a bargain.

lmao... 'a few more' - sure thing, bud...
Here are a few similar but 'made-in-USA' 12V/100Ah LFP batteries - just a few bucks more @ $650-675.

...not that I'm suggesting anyone buy the cheapest no-name China-direct batteries they can find. There are more reputable options available without breaking the bank.

"Made in USA" - lol. The cells, the BMS, all come from China. All they probably do is connect the BMS to the cells here.

OP thanks for sharing. This is first time I have seen less than a $1 per aH.

I wouldn't really recommend a no-brand like this, at least, go with Eco-Worthy.

Multiple deals at < $1/aH here on SD now. Here is a recent one 100 aH for $85 (expired): https://slickdeals.net/f/18451876-solorage-x-12v-100ah-lifepo4-mini-lithium-battery-84-99?src=SDSearchv3&attrsrc=Thread%3AExpired%3ATrue%7CSearch%3AType%3Aac_keyword%7CSearch%3ASort%3Arelevance%7CSearch%3AHideExpired%3Afalse

The FDA disallowed drug names from conveying their function some years ago, which is why we get Latuda. You'd think it helps with flatulence or something.I have zero experience, and there's plenty of good Youtube content on this subject.I'd be comfortable with any brand because as was already mentioned, they're all using the same components anyhow.My curiosity in these LiFePO4 are for a trolling motor (which I don't have yet), or to replace the battery in a vehicle.
Any of these will work for your future trolling motor (assuming you've matched voltages obviously). None of these cheap ones will work as a car starter as they can't deliver that much instant amps. You can find a lifepo4 starter, but it will be explicitly labeled as such and those start at about $300 last time I checked.

Good points for others to consider. My application is in a PHEV, which doesn't have a starter. The battery is also in the cabin, so freezing isn't a concern.

Think of the name like a burner phone number. They dump this junk, change names before the product catches fire, and rinse and repeat. They are not looking to build a good reputation and brand awareness.

Why do you need an app to put a battery in a piece of equipment? Are you planning on asking it out on a date? Stream some music to it? Do people obsess over the charge status of a battery that much? I just need my mower to work.

Do you mean like for remotely monitoring the cell voltages in the pack, or checking the charging status or amp draw when they are down in your RV or boat battery compartment? Or when you are using it as part of an off grid solar battery bank? Do you know what these batteries are used for? This is not a car battery.

The dimensions or physical size of this battery are unclear. Pics here show two different sizes. Size does matter sometimes, not just the capacity; I bought a pretty large one for a solar generator project, and immediately wishes I had shopped a little more and found something smaller. If I'm reading the confusing listing correctly on their site, this is a 13" long battery, meaning it is pretty large.

I'm curious if I could use with with an inverter as the backup battery for a sump pump. I've never pulled the trigger on the standard lead acid marine deep cycle ones as I wanted something that lasts longer for the price.

Can these charge in a standard 12v SLA system?

I have no experience with them at all, but I often see them offering prices seem to good to be true. I'm waiting to read people's actual experience with them.
