It is $399 (+ tax) with the coupon code.
I'm getting 4 more, and doing a full hybrid inverter battery backup.
Ran these off a 1000w inverter for 16hrs during Milton before the inverter took a crap. Paralleled two batteries, ran two full size refrigerators, and it was still over 3/4 capacity per the inverter.
If you don't need the bluetooth BMS (which I don't, really), these are a smokin' deal.
Just trying to find an external BMS that I can use to monitor all 8.......

I think I paid around 900 for a 300ah li time a few years ago.
Just looked the Ecoflow XTi connector is 300V, 14 ga, 80c.
Here is an example of an inline: https://www.amazon.com/Bussmann-H...B000LEQVRQ.
(assuming you are looking at one 12V external LFP)
Just be aware you will need to charge the LFP separately from the ecoflow if that is not evident.
Battery to inverter fuse/breaker
The battery-inverter connection handles significant current, especially when the inverter is powering large loads, making it critical to safeguard against short circuits or power surges. A fuse or breaker ensures that in the event of an overcurrent situation, the flow of electricity is cut off, preventing overheating, equipment damage, or even fire hazards.
The size of the fuse or breaker should be carefully selected based on the inverter's power rating and the battery voltage. Typically, the fuse is rated 1.25 to 1.5 times the maximum current draw of the inverter. For instance, if the inverter draws 100 amps, a fuse rated for 125 to 150 amps would be appropriate to handle surges without unnecessary tripping. The fuse or breaker should be installed as close to the battery as possible to minimize the risk of damage to the wiring between the battery and the inverter.

Why? Integrated systems talk to each other and provide that data back to the main charge controller, one off systems do not have this communication protocol so if you want to see what is going on inside the pack, this is the way to monitor.
