Sold by Eco-Worthy throough Ebay. Price breaks down to $1.50 per AH for a reputable high quality brand name battery. This is more than 3 1/4 Kilowatts of battery. If my math is right, thats less than 8 cents per watt hour.
Might be for only a couple days so better hurry. I picked up 2 of em myself at that price

Nice price. One could make a pretty substantial power station pretty cheap. A pair of these, one of those all in one 24v hybrid inverter or buying inverter/controller/etc separate, and a little for misc wiring and stuff and mount/containment, and have a scalable big Wh setup for under $1500.

I'm loving this overall downward trend in pricing for LiFePo4 batteries. I knew it was going to happen eventually and the consumer has been getting price gouged long enough for this chemistry which is actually cheaper to manufacture than Lithium-Ion like NCA. Elon Musk has been the only person selling his LFP product (cars) cheaper than his NCA cars since he started selling LFP cars. I'm not saying one chemistry is better than the other but I am saying LFP is cheaper to manufacture than NCA but you wouldn't have ever known it by looking at LFP products compared to their NCA counterparts prices, until very recent.

Don't forget :

LiFePO4 batteries are less of a fire hazard than other lithium batteries because they are incombustible and won't catch fire under normal operating conditions. LiFePO4 batteries have several safety features that make them safer than other lithium batteries.

Oh I havent forgotten. LFPs are better in many ways than other types but this wasn't a convo about that. They are better in ways that we the consumer haven't even been getting the benefits of, until recently, and that benefit is its cost. It's cheaper to manufacture LFP than other Li-Ion chemistries. Up until now, only the battery suppliers and the large corporations have been getting the most from that benefit. (as extra cash in there pockets, not ours) It's about time they passed that benefit down to the consumer. IMO its one of LFP's best benefits. Which we the consumers are finally starting to benefit from.

Great for mobile applications. I like the price. But not sure if this has quality internal/low temp cutoff. Li Time would be a decent choice for that.
I run a couple 100Ah BB100s. They work well, but way overpriced. What sucks about 12v LiFePO4 is the low voltage requiring huge cables to deliver the current. 48v systems would solve that problem, but would require a 48V to 12V converter to run 12V accessories, and a separate 48v inverter to deliver 110v.

Same Wire sizing recommendations as in lead acid batteries, correct?

Correct. Wire sizing has much more to do with how many amps you expect to be pulling through those wires, not the chemistry of the batteries. Whether Lithium Polymer, Lithium Ion, Lead Acid, Nickel Cadmium or any chemistry at all for that matter, 12volt DC is 12volt DC and the same rules will apply to how thick of wires you will need relating to how much current you'll be pulling.

I believe so. The market is getting saturated with so many manufacturers and the competition is fierce. The prices IMO will continue to trend down. How fast? I don't know but just a couple years ago, a regular standard sized 100ah LFP was around 400 and up, with anything below that being a good deal. This deal at 420 bucks is 200% more juice than a standard 100ah battery with the price being in the same ballpark as a 100ah batteryfrom just a couple years ago. You'd be looking to pay right around $1,000 for something around 300ah just 2 short years ago so who know what another year or 2 will do to the pricing.

If the specs is correct about max discharge current 200A then that should work for golf carts.
