Comment on Biwatt releases 4.5 kWh sodium-ion battery - Energy Storage
WhiteOakBayou@lemmy.world 1 day agoI can’t answer the why but there was a warning sticker on my new lifepo4 batteries with similar limitations. So not chemistry dependent.

Holy shit those are pricey.
How do you like them?

A lot. My use case is off grid camper living. We live in a camper about 4 months a year not counting weekend trips and vacations. Lead acid batteries have to be minded and hate being discharged below 50%. The lifepo4 batteries have a super low self discharge rate, don’t need any minding and can be discharged down to 15% or 10% before they start degrading. I would need 400 Ah of leadacid batteries to equal the 200 Ah I have now.
So weight and space savings, no maintenance, harder to damage. I definitely recommend.

This runs my house and I’ll have to be replacing them in the next year or two so I’ll look into them.

They may struggle to reach price parity for a set up where space and weight aren’t limiting if you’re getting a full 5 years or whatever out of your batteries. I never did with lead acid but maybe I’d take care of them better if they ran my house!
Do you mind sharing your reason for using a battery bank to power your house? Is it solar or a backup charged by the grid?
