I mean battery breakthroughs are real though? BYD is now demoing 0-80% in 5 mins on production vehicles in China.

The price of the 50kwh unit I had put into my house was very low.

Sodium ion is ramping up too but is commercially available. That straight wasn't possible a few years ago till the electrode breakthroughs.



Do you have any pointers on said 50kWh battery? Asking for a friend.


This was the group who did it for me in Australia: https://voltxenergy.com.au/

It was under subsidy, but I got about double what I was going to get about 6 months prior. There are 50kwh units going on AliExpress for about $12k AUD outright so I think there's been another step down in per-cell costs which is tickling through.

I'm waiting for a price cut to make outright purchases a bit more affordable but with a wholesale electricity service plan adding another say 100kWh probably works out.


Yeah, unfortunately shipping anything with Li-Ion to my friend is pretty tough. Especially anything larger than a power bank. Amazon isn't even shipping those.

I have hopes for Sodium-Ion cells, they should be way more shippable and presumably a better fit for residential power.
