They have had them, then not, so in and out of stock. It is a relatively new product for them, I think seeing a lot of demand.

You could get a 3 pack of 280 AH Li Time with 200A continuous BMS and low temp protection for $1536
That would give 600A continuous.

One thing to consider, I have had drop in lifepo4 with and without bluetooth. IMO bluetooth is a must.
****edit** As a matter of fact bluetooth and an on/off switch somewhere.
The reason for that is these batteries have a ton of electronics inside. They also have many parameters for shut down and protection modes and they also occasionally malfunction. Troubleshooting is SOO much easier with bluetooth. You can see if charge and discharge mosfets are on or off, if there are any codes or warnings etc and sometimes cycling power resolves things. And lastly, with no on/off button the basic batteries can "go to sleep" and must be woken up by either applying a charge or a load. And sometimes that may not work due to various conditions.

I wish my batteries talked to each other. Now ending the 3rd season with them, each of the BMSs is going a good job. This is where a good BMS also comes in. What I mean is, that all 4 batteries when I Bluetooth into them are 1 to 2% of SOC of each other.

This really depends on the software and hardware of the BMS. So this is important in the buying process. I would try to get a battery with the best BMS that I could. Which is not a easy task in researching.

I found this battery thru Panbo. Very interesting! Sun Fun Kits SFK-275EX 3.6 kWh 12v Endurance Dual Mode Heating Smart Lithium Iron Phosphate Battery, 6000 Cycle rated, dual heating mode (standby & automatic).

Panbo just came out with an article on them today and these batteries look great. Cost is good too,

I just happened to see that today. It is a solid review. However, I don't know who the author is. He may be the smartest guy in the industry, but it isn't my industry so I'm clueless.
Another consideration for me is the prospective longevity of the company. A 10 year warrantee is useless unless the company issuing it is still in business 10 years on. For example, who is going to make good on your bad KiloVault battery? Unfortunately it is difficult to judge, as few of these companies have been in business even 5 years and quite a few have exited in that time. SunFun was started in 2021 (Epoch also), 3 years old and offering 10 year warrantees. They are becoming cheap enough that you may not need to depend on the warrantee, but if periodic replacement is contemplated, then the installation should be generic, rather than specific to a brand.
This is also true of the "serviceability" claimed for some brands. The cells will probably be available 6 or 8 years on, the BMS almost certainly not.
For those technically capable, those are good arguments for rolling your own.

Agreed. Which is why I'm definitely not going to ever attempt that.
