Time for Lithium House

That 300Ah I think you are referring so is the soon-to-be-released?

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,
