This is the 100A LiFePO4 from Redodo.
I've had this in my Amazon shopping cart and I see that today's price is very good. $269 - $40 = $229 with free shipping. https://www.amazon.com/dp/B094NN5KWY
I ended up buying another pair at an even better price. $455 - 10% = $410 or $205 each (but you have to buy a pair) https://www.amazon.com/gp/product/B0B2QP1T5T
Note that these physically are the same size as a lead acid AGM 100AH battery so it fits into battery trays that used to hold AGMs. 100AH 12V LiFePO4's are also being sold as 'minis' where the case is smaller, but many of those are using pouch vs prismatic cells. I don't have an opinion on one being better than the other (pouch vs prismatic), just letting you all know.

Thanks, Dave. I ordered one. What do you think about paralleling this with a 30Ah battery connected to a solar charge controller? Is there any reason not to do that with different size LiFePO batteries with built-in charge controllers?

Paralleling is safe. In series is a no no. You do want to charge them individually fully before connecting them in parallel as the current draw can be very high due the low internal resistance. BMS should protect it but no need to stress the setup unnecessarily
