$560 after tax credit. However I would be hesitant on adding this in my home given that it is not UL listed. Last thing i want to do is catch my home on fire from saving a few bucks for not certified backup batteries.

48V, 100Ah is actually 4800wh. Why is this list 5.12kW?

48v lifepo4 batteries have a nominal voltage of 51.2.

https://www.youtube.com/watch?v=-4llmbbQ0X4 Will Prowse has a good review of it. He says they are working on their UL listing.. the website says they're UL certified but I don't know if they have it yet or not. Eco-worthy is probably a lot better than all of the nameless brands listing batteries like this on Amazon.

I ordered mine on Sunday at the tail end of previous sale (because of the looming tax credit changes), at the same price. I'm still not set up with my V3 batteries, but they arrived on Tuesday after ordering Sunday night, FYSA. I have an existing rack of 6x5.12kwh V1 batteries as well that seem to be doing pretty well also.

I got 4x of these, a 6 slot server rack, and a 5kw hybrid inverter for $3448 after tax/shipping from the last deal. Debating picking up one of the v3's to put as the master so that it'll have display support.

Most people hook these to an inverter to output 120v or 240v.

UL listed version will be available mid to late August my rep said. They are mechanically the same as v3 but these in the post aren't stamped

Will Prowse had a good review of this newest model, which this photo appears to be. It's not UL-listed yet, but it is a decent price.

This gets my award for most confusing downvote. Like who can be mad at math?

at $200 each those are a good deal, but at 12v that will be a lot of large cables and connectors, to series sets of 4 to make a 48v system, then you still need to add the breakers and make a mounting system. For a 12v system they are probably great. Last year I bought 4 of the Eco-worthy 150AH that look the same and paid less than $200 each.

lugs are $1/each. You need +6 extra lugs $6. put them on the ground or get a 2x4 and cut it to make 4 legs and put some plywood on them to make a table. $15. no additional breaker needed between 12v batteries.

Total additional cost $21. Savings $400+ . I got a 7 night vacation on the beach for $650.
