Vidim na jednom sajtu nude iznajmljivanje za 450 $/ mesec. Ako je to uopste isto. Odatle pretpsavis da bi cena mogla biti 50-100 hiljada dolara.
Nisam citao detaljnije, jesu to kondenzatorske baterije? Njima kapacitet ne opada vremenom, vec su prakticno vecne?

To su elektrohemijske baterije. Za istu količinu energije moraju biti veće i teže od olovnih i litijumskih. Ta činjenica, uz membrane, "začinske" elemente, kontrolnu elektroniku i to da su relativna novotarija ih verovatno čini toliko skupim, čak i ako ne sadrže litijum.
Nepoželjni procesi se u ovakvim baterijama u velikoj meri mogu poništiti, pa vek može biti jako dug. Nadam se da neće dugo trebati da dođu do neke razumne cene.

Edit: Evo približnijih brojki:

According to Bloomberg, the average cost of a lithium-ion battery is about $137 per kilowatt hour and is forecasted to drop as low as $100 kilowatt-hour by 2023.
However, these are the cost of the cells only; a complete Li-ion battery system for grid-scale stationary storage currently costs approximately $350 to $400 per kWh. It has been estimated that the overall cost for VFRB Systems are $500/kWh, but that will fall significantly over time as production volumes increase.

Znači da se može reći da to već jeste isplativo u odnosu na litijumovu tehnologiju, s obzirom na bar dva-tri puta duži životni vek.
