Genius US company makes iron battery that competes cost wise with lithium!

Not the video I wanted but you get the idea. ESS makes iron/saltwater flow batteries that go into 40' shipping containers. Thus offering 50 kilowatts of energy. "Enough to supply a block for four hours." Plus the price competes with lithium!

Simply built, the parts are available at Home Depot. Did I mention that the price competes with lithium?

    I won't live long enough to see this in RVs.

    Is there a version that could fit on my wall in my garage?

    At the moment, focused more on the industrial scale - A pity, as no reason it couldn't be on a residential scale:

    Although not exactly the same electrolyte, the zinc bromine flow battery offering from Redflow is of residential scale.

    This article has some interesting information with regard to flow batteries not being practical in small scale residential applications.

    Random reading material should one be interested.

    Who needs a generator for off-grid low solar periods - just haul your battery trailer into town and have it recharged :-).

    I am available for custom hardware/firmware development

    Yeah, smile over my death when it happens. Don't you think you're jumping the gun, a bit? I'm not even in the cardboard box, yet.

    I was being a bit sarcastic when making the thread title. Don't you think that "iron batteries" should be less expensive than "lithium batteries"? 

    Lithium batteries can be made from a broad array of materials, few of which are cheap. Iron batteries are made of iron with nickel plating. From here - that looks like it should be relatively inexpensive.

    Perhaps but for RV owners, iron-salt batteries that fit into an RV's battery bank don't yet exist. The notion of getting parts at Home Despot gave me a chuckle.

    I believe the video said the parts were available at HD - guessing the storage unit perhaps? It was made by a young dreamer. They are typically more interested in spin than reality. 

    As far as I know, iron solar batteries are comparable in size to lead solar batteries. This video depicts an industrial battery. Going off of memory here.

    Again, there is very little material available on these batteries and as I mentioned, I'll be way dead in 2064 so these batteries are useless for me. I see no production and honestly, I'm almost 65. I don't want to build my own f-n battery. I'm tired.
