Ah watch, they will bump the price to $3199.99 now - this happens when they have overlapping coupons and/or miscalculate; they don't like selling these batteries new for under $800 (by much), unless you buy 6+. Also I bought a 4pk last month - keep in mind these are the new V3's which did flip the sides of battery terminals, if you're considering mixing with their V1/V2 battery stack for some odd reason.

Until tariffs kick in by then…. But so many things are in the air at a given notice everything might change overnight.

The refurbished bundles are $750 per. Does anyone know if those (4- and 6-pack) include the rack?

Keep in mind refurbs technically (?) don't qualify for tax rebate since they aren't "new", unless I misunderstand something here.

The federal tax credit is good as long as it's installed and operational before Dec 31 2025. Just make sure it meets requirements.

Insane deal and you can hook them up to some power stations as an expansion battery without a lot of operational expertise, like Anker and Pecron now, with all the recent mods

Also this includes the battery monitor that ONLY works with V3 it will not work connected to a V2 battery, so I have no idea if it will work if you have V2 and V3 batteries interconnected (or if they support being interconnected at all as far as communication goes)

The battery monitor should work if you connect it to a V3 and it cascades into V2 or V1 batteries because the only thing missing (from my understanding) is like the power aspect to that port. The newer V3 batteries have some power being supplied via that port, where-as V1/V2 do not. I've tested it directly on my V1 batteries and no dice (no power), but I bet I could read all the batteries if I had all 12 of mine in the same stack (I have 2 stacks right now, one V1 x6 and one V3 x6)

If you test let me know, I have 12 V2 batteries so not really wanting to add more since my racks are full and I do not want the swapped terminals as I use bus bars and have all same length wires.

I really liked the idea of a self reporting monitor, but I already bought a Victron Shunt to use on the setup if need be like I use on my other setup, and its great and it easily is interfaced into my smart home dashboard.

If it is just a power thing, someone like me can make an adapter for the V1 V2 batteries pretty easy.
