The same battery but with Bluetooth integration is just $10 more and a much better deal that allows monitoring and has low-temperature shut off so it doesn't get charged if near freezing, which damages lithium-based batteries.

It is $399 (+ tax) with the coupon code.

copper ones. If your not willing to do a little research on it, you probably shouldn't tackle that project. How do you even plan on using it? If you want to charge your Eco flow with it directly. expect a very slow rate. approx. 100 to 120 watts unless you buy another thing that boosts the voltage and I'm not even going to get into it. you better do your research. All I can tell you is it's not as simple as adding an Eco flow branded expansion battery. After you do get it connected, you'll still have to figure out how to charge it separately than your Eco Flow. Your EcoFlow isnt made to chage other 12v volt batteries. Not saying it's not more cost effective... It is more cost effective , but there's some big time trade offs and a lot more too it as well.

I got 4 of these the last sale, it's just over 13kw at 48v in series.
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.......

Wow! 4 of these batteries = 13.4 KWh for $1519. That the best price I've seen so far on this amount of storage! That's under $115 per KWh.

Quote from testshoot :
You want to get a XT60I connector vs the non-I cable. The I version of the cable "fools" the Delta into thinking it is a solar panel. Will charge up to 500w vs up ton200 watt. I bought mine off of AZ.
Won't help for a 12v, as your going through the solar port. The max it can kinda do is about 85-100w. (Same as using the car adapter). It's not the I cable limiting it, it's the voltage of a single 12v. Realistically, this is still pretty good, and I've done this for a few years with a delta mini

How do they compare to these? https://www.18650batterystore.com...eve-lf280k i know the voltage is lower but comes out to a similar per kWh. Seems much better built and easier to connect with busbars that are included.

You need 4 of those to make the 12V, add in shipping and it might end up the same or more.

That aside, DIY is usually going to be cheaper but that involves its own cost of time & effort.

I didn't mention in my post, but you can put a buck transformer in the loop to increase the voltage. There are multiple YT videos on people doing it.

Depends on how you wire it. In series you add the voltage and keep the Ah rating. In parallel you add the AH rating and keep the voltage. What trully counts is the Wh rating (Ah x Volts).
