We must be talking about different companies. Donut Lab is famous for making funny looking rear wheels for motorcycles that look like a donut... big hole in the middle. I have the paper specs for one of their motors (of a somewhat different size), and they look perfectly fine, and are more...

Consider this: People were nearly as skeptical about the LFP cells I used on that little car 15 years ago... especially re their bursting into flames. I still have them, and they came from some-fly-by night company in China (CATL or some crap like that). Half of them still have their little...

It's fun to imagine that it does, but that is not the case in real life. The Insight is far more efficient at moving one or two people and some luggage, if you are thinking about resource consumption and generation of CO2. I am something of a "nut" about such things, so when my wife...

I am also skeptical, but have been in Marko's position on a far smaller scale. His slightly early original announcement, (originally a quarter away from delivery) gives him the ability to gauge whether he can sell the bikes: they are three times the price of a Honda 600, that performs about...

Of course, a dealer can ask any price he feels he can get away with, just as anyone does when selling a house. Only a fool would pay more than 40K for a new Bronco in 2022. That "MSRP" is fiction I assume, at about double what I paid for my 2025 Lightning.... which according to Jim Farley, is...

To continue my rant: Who are you up against in negotiating a vehicle price, direct vs dealer: 1: A huge corporation with multi-million dollar ad budget, and billion dollar losses they are trying to recoup and hundreds of lawyers on staff... or 2: some poor shmoe who has to sell cars to keep...

If MSRP is 30,000, only a fool would pay more than 27,000, no matter what the dealer is trying to sell you. Among numerous other vehicles, I've owned a Saturn and a Tesla. Paid full hit retail (MSRP) for both, because of manufacturer price control. Both were substantially overpriced...

Heck No!!! I would not want to insult Donut Lab like that.

The intentional shadiness of staying dark, only revealing partial information. Accusing everyone else of being the problem because "we're the real deal". I didn't get that impression from his presentation. He seemed to outline the way things have gone, with the expected skepticism, but he...

Nor is this very confidence inspiring: " South African native Elon Musk, who claims he is a Cultural Christian, built Zip 2, a city guide that solved some problem and reportedly made him a millionaire. This despite having no education beyond the bachelor's level. "

You are probably wrong about the "trusting" part. I've participated in putting a couple frauds out of business; I didn't believe in Santa Claus at any age beyond 3, and don't believe the religious myths that people use to comfort themselves and to feel superior to the "others" who have equally...

I keep my truck on the calm screen all the time, but have had it switch rarely to some other screen -- which I attribute to operator error or a minor bug.

I see UFO's almost every day. Sometimes I think it is an osprey... or maybe an eagle. sometimes, it becomes identified: "Oh, it's just a turkey vulture." Remember all the UFOs reported around new Jersey in Late 2024?

yes, and pretty highly regarded.

What does "that" refer to? The fact that they are publishing test results?

More on this: I have about 24 old 60 AH LFP cells, all of which have lasted longer than I anticipated when I bought them 15 years ago. Some have been abused by neglect. Some have been treated with respect, and -- apparently -- identically: always charged together; balanced periodically to...

Suppose you were a small company with a breakthrough technology. Do you go to Ford and say "We want you to put our batteries in your Lightnings (that you are giving up on). Good luck with that. Do you go to Toyota, and say "Scrap your own SS plans. Use ours." Good luck with that. Aware...

From VTT in Finland: "VTT Technical Research Centre of Finland has conducted measurements on the properties of Donut Lab’s battery in its research laboratory. Donut Lab will publish the research results as a series on its website, where they will be available to the public. Donut Lab also...

In the particular case from Reddit, the Ohmmu BMS is clearly at fault, if the post is to be believed. There is no way that one cell of a LiFePo battery can get as low as 1.0 volt, with the other cells being "normal" (presumably 3.2-3.5 volts) with a functioning BMS. A "smart" BMS should give an...

No one should ever try to charge any lithium chemistry battery that has one cell at one volt. That cell is shot, and is well below the lowest voltage to attempt a normal recharge. The Ohmmu BMS should have prevented any current from going in or out of the battery, no matter what chargers or...
