battery based on sodium ion (salt)

The initial cost is about 3 times the price of AGM. Going by cycle life they should outlast 4 sets of AGM. We don't use Li so I don't know how they compare.
Aquion was working to get their specific charge profile programmed into the major brands of inverter/chargers so it could be selected in a menu. Most models now have settings for flooded, AGM, and a custom one you can program yourself. At the time I think only SMA had the menu item in their Sunny Island product. The charging, if I remember correctly, was a constant voltage. There was no separate bulk, absorb, and float voltages. The nominal voltage was a little lower than 48. Maybe around 46 I think.
