This is a hell of a deal. .33 per kwh for LFP before the tax credit. These SHOULD qualify for the 30% tax credit if you haven't taken it before which would bring the per kwh cost down to .233 cents per wh. That's the lowest I have seen regardless of chemistry for a major brand.

not a very customer-centric policy. this will lose them sales for those smart enough to read it before they buy, like the should. i can see the slickdeal complaints now, for all those that didn't read it.

Sadly you must buy 2 to get this very nice deal. Unfortunately you can only team two extra batteries per Delta Pro and since I only can add one more there's no joy to be found here.

You can mix and match other extra battery. If you have delta 2, delta 2 extra battery also on sale. If you have delta max, delta max 2 extra battery also on sale. Buy 2 to get 25% off

Why " if you haven't taken it before"? Is there such a clause? Plus this is the first year there is a battery tax credit.

also, this deal is just for batteries, you'll still need to shell out 2200 for the delta pro.

Why do people keep posting this about only getting the credit once? Please show me where on the irs website that it says you can only use the credit once? I am not talking about some other website (most of them are wrong because they are looking at the older credit). I am talking about the irs website or irs document.

What else would I need to buy if I want to buy 2 of these to take advantage of the deal? Want a whole house (or most of the house backup - fridge, internet, some lights, boiler) and realize just these two won't cut it? New to all this and hard to find info.

You need the Delta Pro as stated in the original post.

Thank you. Can one Delta Pro be paired with two of these? Do I need the double voltage hub?

One Delta Pro can expand with up to 2 extra batteries. You don't need the voltage hub. I am not sure but I think the voltage hub is for connecting 2 Delta Pro together to be able to get 240v output instead of 120v. I do know it's not required to hook up extra batteries.
