off grid solar, house batteries for rv, camper, boat. If you've got 12 V devices you can run that directly from the battery without any inverter which is nice.
I have a power station but its internal battery is a 48 V, so when I run 12 V things you lose some efficiency stepping it down to 12 V. I also have a 12 V battery and I'll just often run those device devices directly from the battery and I get much more run time per ah of battery.

Lol. These were NEVER $1,055. These "sale" prices are ridiculous. Like it's still a good deal. I bought two of these at ~$300 each last year and love them, but please they need to stop saying they're marking it down 75%!

No. These are NOT starter batteries. That isn't how it works.

Be cautious of this seller, as it might be a fake. While the battery is great, this seller might be a scam.

No. This is way bigger than a car battery. It's for power storage. I got two of them in my trailer. Works well - you can run the air conditioner for 8 hours off them.
You must have a small AC unit..most AC units use closer to 1350 watts. That battery will last less than 3 hours with a standard 13500 btu unit running constantly.

It's about the same size as a car battery, but it definitely can't be used as such.
Actually it's not, this one is roughly twice as large as a standard automotive 12v.

It really depends. If your AC is running full power full blast then yes it will drain this pretty fast. However most of the time AC will be running at lower power, just maintaining the temperature in the home.

Think of a fridge. It takes a lot of power momentarily starting up, a decent amount bringing temperature down to levels and then very little maintaining that temperature.

But yes if you are trying to cool your room from 100f down to 70f it won't last long. However maintaining 70f takes much less power.

I bought these at $376 each in February 2025, $434 In May 2024 on ecoworthy store on eBay, and thought I had gotten amazing deals. They arived from China intact. This store on AliExpress has 100% positive reviews, 4.9. I think this is legit. If I didn't have 4 batteries sitting in my closet, I would bite...

Ok, I put my money where my mouth is and bought another. Lithium is so much better than lead. They can be discharged more deeply, giving more usable charge. Lighter. LiFePO4 has better temp range. Others have reported 300 AH for this battery as well.

Huh? Nope. Extreme temps are challenging for LFP batteries. At least compared to lead acid type batteries.

can i use this to charge my ecoflow power station?<br />
<br />
Im thinking of connecting it using alligator clips from 12v batt to xt60 to the back of the power station. not sure if this will work and advisable.
Yes, definitely. I now have 4 of these in a 25.6V series parallel bank configuration providing power to an Eco-Flow Delta 3 Plus via the XT60i inputs.

I charge the battery bank from solar through a Redodo charge controller.
