battery based on sodium ion (salt)

Hi KD4UPL,

Thanks for the insights.

How does initial cost compare with LI? with AGM?

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.

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.
