Yes. It's all time low. I bought 8 of them last year at around 400 a piece but haven't got around to set them up.

I almost pulled a trigger on them last year, but they were the dumb version, so I waited. Grabbed a few of the metal case 165AH to hold me over, EW was substituting them for plastic 100AH, so it was a bargain at the time.

So 4 of these would be like half the price of the cheapest "DIY" ~15kW battery kit (Yixiang), pretty tempting.
Would be nice to have a single BMS for all the cells in a 48V bunch though. What's the consensus about ripping out the cells and reforming into larger bunch, not worth it? I've watched a lot of videos on the 48V kits but haven't investigated just using these 12V batteries instead, mostly because I want at least 64kWh and would prefer the cleaner look, but saving ~50% is very appealing.
Other issue is I assume these are limit 1 per account.

In for another at this price! Already have one that I use to increase the capacity of my EcoFlow Delta 2 Max.

What is your set up to connect this kind of battery to your ecoflow?
I have a Delta 2 and want to expand the capacity instead of getting an extra battery from ecoflow.
Thanks!

I think the XT60i cable yields about 160 watts, iirc.

Kinda blows my mind that you can get 4 of these for ~14kWh for less than I paid for a single 48V/5kWh rackmount battery ~3 years ago. (assuming the coupon isn't just single use)

You could do a few things:
  1. Highest throughput capacity, safest, and most versatile: use Ecoflow's 800W or 500W alternator charger (this option lets you charge & reverse charge, which can be very handy since you don't have to worry about a way to charge the LFP)
  2. Low throughput but easy: XT60i cable for 15A charging, but this will only yield about 200W max into your Delta, and you'll have to figure out another way to charge it
    1. With a Delta 3 Plus (or their other units with 2x 500W inputs), you can make/use a splitter to 2x XT60i, feeding both solar inputs to get about 400W combined (use at least 10 AWG thick wire for this since it'll be pulling 30A continuous)
  3. Medium throughput, more expensive, more capacity: Get two or more same-sized 12V LFPs, wire in series, and feed into solar via XT60i. 2 in series will be around 26V * 15A = ~400W. You could technically do 3, too, for '36v' which would max the 500W solar input.
