Tesla said that they will use LFP batteries from now on in all "standard range" cars. https://www.cnbc.com/2021/10/20/tesla-switching-to-lfp-batte... As I understand it, the "standard range" cars are no different from the long range cars, other than a software flag that allows a greater battery discharge. So this will complicate the Tesla fast battery swap stations if they ever actually build any of those. https://ww…

"So this will complicate the Tesla fast battery swap stations if they ever actually build any of those." They aren't planning do battery swapping. None of their recent designs have any provisions for it. That was something they considered early on and then abandon once they advanced their fast charging technology.

They took a half billion in subsidies from California for battery swapping and never planned on actually implementing it broadly IMO. They just met the letter of the rules to qualify, then move HQ to Texas after subsidies run dry and they don't want as much taxation as normal CA small businesses who subsidized them.

Just in case -> BYD Co. Ltd. is a Chinese manufacturing company headquartered in Shenzhen, Guangdong, founded by Wang Chuanfu in February 1995. Perhaps someone can comment on quality of these batteries compared to the current car batteries Tesla uses?

Is arbitrarily pointing out “fyi this is a CHINESE business” the new “fyi this is a JEWISH business”?

Well, BDS gets away with saying "fyi this is an ISRAELI business"

As a young(ish) person, I've definitely heard "fyi this is a CHINESE business", but haven't really heard "fyi this is a JEWISH business" or "fyi this is a JAPANESE business". Are there communicable/generalised messages or stereotypes people are trying to invoke with this sort of thing, or have they always just been intended as slander?

There are some striking parallels between China and Japan, not so many between China and Holocaust victims. In the 1940s, great industrialized nations vied with each other to see who could commit the biggest atrocities on the other guys. Japan lost out, but once set straight, they began an impressive multi-decade recovery. In the 1950s, Japan's own considerable efforts, along with help from their former enemies, star…

It's okay to prefer American made products without bringing some kinda racial implication into it. The whole "buy local" movement is simply an extension of this. It's okay to prefer to trade with your local economy.

While we've never been at war with China, it's not infeasible given their attitude towards Taiwan. And there's very real trade-offs with convenience of importing everything vs. the resiliency of having your own supply chains which we saw a small taste of in the early days of 2020 with medical supplies.

We already buy many China-made things including iPhones and we don't bat an eye at the "Designed in CA, made in China" label... but there's a lot of us that feel uncomfortable with yielding our manufacturing base to globalism, not least of which is that it puts you in a bind if you need to stand up to said country when they encroach on more ideologically-aligned democracies.

BYD is also a competitor in the electric vehicle space. https://en.wikipedia.org/wiki/BYD_Auto (They make great KN95 masks, incidentally.)

Any references what makes their KN95 great ?

So Tesla's Li-ion batteries are going to have a significantly higher mass energy density - these are around 150Wh/kg vs 230Wh/kg that Tesla can currently muster. This is somewhat mitigated by the fact that LiFePO4 handles 100% charges and 100% discharge, so in practice the protections on Li-ion means you can only really get 190Wh or so out of them every day, significantly narrowing the gap. However, these are going t…

Adding to this info - LiFePO4 batteries are far more chemically stable and therefore need no cooling system. I have LiFePO4 home backup batteries and they are completely passively cooled.

Weren’t LiFePO4 the batteries that need to be charged in fireproof bags because they have a tendency to spontaneously combust?

Those were the horror stories I read about back when I had some for my Walkera rc helicopter.

Overkill Solar https://overkillsolar.com/ I've ordered twice, and plan to order another 5kw soon After having 2 unbranded circuit breakers fail on me. Everything else will be Blue Sea, or Victron. They're the most expensive, but they feel as high quality as they are expensive which makes it worth it. Especially considering the alternative is explosions followed by fire.

Victron is bullet proof. I've seen their inverters used aboard working vessels for decade after decade without so much as a glitch. Highly recommended.

Looked them up and for LiFePo4 batteries they seem to charge several times the eBay prices. What could they possibly be offering at that premium, given that it's almost certain they don't make the batteries themselves?

Better: * can charge to 100% all the time * no rare earth minerals * stable Worse: * not as energy dense * US doesn't make a lot of this type of battery

The US doesn't make a lot of this type of battery because there is a consortium of patent-holders who charge enough to make LFP less economically viable that wasn't able to secure all the needed patents in China.

A123 systems make LiFePO4 batteries without paying the royalties but they're still even more expensive than normal Li-ion.

Nope, that's probably LiPo you're thinking of. LiFePO4 doesn't catch fire much.

I never tried their KN95s but their surgical masks are pretty great, the ear hook is thicker and softer with better elasticity and the nose metal band felt nice. I wouldn't go out of my way too much though.

I think those were LiPo batteries - i.e. lithium polymer. Same kind in a certain infamous phone that was banned from flights.

LiFePO4 are lithium iron phosphate.
