battery based on sodium ion (salt)

We're dealers for these batteries at work. We should be installing our first set in a house later this month. I've been to the factory where they are made.
They are only offered in 48v and they are quite heavy (like all batteries). I would only see a good fit with a very large RV. The reason they are limited to 17A per stack is due to the size of the internal and external wiring. They really aren't designed to deliver large current output. They are more for lesser draws over a longer period of time like you would find in an off grid home. Also, they are meant to be installed with many many stacks in parallel to help achieve a greater current output.
If their claims of cycle life prove to be correct this will be a nice step up from using lead acid batteries in off grid homes. It will reduce battery change-outs by a factor of 3 or 4 due to these batteries longevity.
