Clearly no one is paying $1,121.97 for one of these, but $244.27 (plus applicable tax) is a good price. New Years Super Deal at $269.27 and use USCD25 at checkout to lower the price to $244.27.

This is one of the lowest costs per KwH I've seen.

They do sales on these, but it's a bit cheaper. But the big thing is making sure people understand that you have to have an inverter to use this battery, and it's not the same thing as the "solar generators" that are posted on here frequently.
But if you have an off grid setup, this is a good deal. They also have good deals on inverters and more deals on their ebay site.

There are a lot of integrated inverter/battery/MPPT units that take 60V DC charging that the manufacturer's Extra Battery covers. These hooked up in series instead of the more expensive Extra batteries, makes for quite a large backup system for off-grid or hybrid home application.

What's the best cable to use to connect this to an Ecoflow?

No kidding. I don't recall seeing less than $70/kWh before.

If this was 48V it would be an insta-buy for me!

The simplest way is an XT60i cable into the Ecoflow's PV-Low input. But that is only one direction, so you'd need a separate solar charge controller to recharge this battery.

Something like this: https://a.co/d/baaSP4U Keep in mind the EcoFlow won't charge it like a true backup. You've got to get a separate solar or AC charger

Thank you! Is there a type of cable that doesn't expose metal? Want to keep it away from the kids. Also what would you recommend for recharging?

I'm using the XT60i cable that @SeriousWallaby890 mentioned to connect this exact LiFePO4 battery to my D2. I've got two Ecoflow D2's and use this as an extra battery. I also have Ecoflows extra battery for the D2 but for the price and size of battery... getting the Lifepo4 and using a XT60i cable.. will get you more runtime but will charge it at around 180W.
Here's more info on reddit. https://www.reddit.com/r/Ecoflow_..._12v_batt/
This video really helped explain it all.. probably watched it 100 times. https://youtu.be/YAcNzTTvL_Y?si=t5PWQmbiQGp3i1Xg
i'm using the Vevor 12v 55amp RV charger ($66 on amazon now which is a good price for a charger this fast) to charge to my lifepo4 batteries.. which i use as a extra battery to go w/ my Delta 2's. The 10/20amp chargers online take forever to charge especially with this size of a battery (which i'm using). You'll need to connect the charger to the battery with thicker cables. Wire terminals are clamp-type and will accept 6 AWG THHN wire. (Instructions state min 8 AWG, but 6 AWG is a better match for 55A load.

You can try hacking the extra battery port: https://m.youtube.com/watch?v=Vlz...9ydA%3D%3D

WARNING
You are working with potentially lethal voltages. Different models of ecoflow have different internal voltages. Proceed at your own risk

Bought 3 of these in November.
With the deal then and cash back from one of the big sites, got them for just over $200 after tax.
All 3 charged well. One took a couple weeks to fully balance all cells. Overkill Solar app works with the BMS. 840 amp hours for our new RV for under $700? No brainer purchase.

You can also use the Ecoflow DC-to-DC alternator charger to connect these batteries into the battery expansion port on an Ecoflow without having to "hack" the port. About half way through this video: https://www.youtube.com/watch?v=6lKvOPBcm4M

I also got these Eco Worthy batteries over Thanksgiving for under $200/each and am just using the Eco Worthy Smart Battery Charger, but I also got that from their AliExpress store for like $30 so it may not be as good a solution at a higher price.

I'm using XT60i cables from Amazon and they work well at delivering nearly 200w to the Ecoflow without having to do any mods. If your Ecoflow or other solar generator has multiple XT60/i ports you can plug in multiple LFP batteries at once without having to bother with doing a serial config. I only wanted these as cheap backup to be able to power my fridge during a long outage, so I don't care about being able to deliver high wattage.
