Day traders are dumb money too...99% of them lose money, but they got all the info/data/stats that the pros have minus inside info.

We are still very far from possible production sadly.

At 1:35 is a QRcode visible on the battery. I am very sure it is some identifier number and I know there exists a online tool to insert this number to get more information, but I forgot the name. Is here somebody watching who is into DIY Battery building? Do you know this homepage?

Aptera Needs Unbelievable Support $100,000,000 #ProductionAtBest2026

Good video.

Showing the progress of battery packs to public is commendable for Aptera. But why did Aptera very recently reveal the HVAC part to only a single woman is a mystery to me. Why not showing it publicly?

Steve, love your analysis, keep up the great work!

Getting silly with how many one off parts are going into the first Production Intent build, from the pack, its caddy, to the frame of the vehicle.

Once the CTNS machines arrive, I am looking forward to seeing a video of those machines in action. Thanks for such a detailed video on the battery packs.

Thanks Steve, Neat to know aspects of the Aptera adventure. Barbie was right. "Math class is tough!"

Thanks for another great video. None of the numbers add up but are in the ball park. That's kinda par for the course with lithium battery packs. A couple quick Google searches suggest the complete battery pack will be in the $10K to $12K range which is good news. The engineer seemed a bit too cheerful about the 'better that 400 miles per hour' charge rate. That's 2/3's of the 60KW DC fast charge Chris Anthony mentioned they might get to in previous videos.

As per normal, i'm confused. ¿Why is a single 'bus bar' connecting to both anodes and cathodes?

Apart from the cost of cobalt, earlier cobalt based lithium cells, were a bit dangerous, with a lower temperature for thermal runaway ( you accidentally flashed your youtube dashboard, showing your income for last 30 days.....not bad!)

There are some issues with the battery metal plates that join to the cells. 1. you can see the round positive end pieces are not spot welded into the middle of the metal cap 2. the negative straight pieces spot welded to the edge of the top of the cells is even more uneven. That will definitely be an area of weakness in the design. If that spot weld is not good there wont be a proper circuit to that cell 3. they are using the length of the outer case of the cells as a current path, shortest path is the best path, that will effectively increase the internal resistance a little bit 4. their is only one spot weld used, if somewhere around 5amps is going through those spot welds there is chance it will heat up and basically be a high resistance path and loose energy via heat 5. the single spot welds on the negative ( edge of the top of the cell) I suspect will be problematic, its probably the worst place you can join to the cell.......a nice idea but not what the cells are designed for Aptera really doesn't want to have recalls, as is I think the those metal plates as is are not going to be a long term solution and potentially problematic.

Thank you, thank you, thank you! What a nice educational breakdown for us laymen to have a better understanding of this video.

It is great to see the battery pack being tested, and the PI builds moving forward. Tim really seems to know a lot about batteries. And I'm glad that Chris got him to assist in bringing the Aptera's battery into production.

The 700 in a 21700 cell is the length in tenths of a millimeter. "Large" cells like this don't really need tenths so they're rounded and just called 2170. Tenths matter more for coin cells.

All those hundreds of cells and connections what could possibly go wring . I dont know much but i always wondered why they couldnd make just one giant battery sort of llike a conventional car batery but much larger . Then it wouldnt take all those tiny cells and connections .

Cobalt extraction = genocide in the Congo

The battery pack does seem like a great design. I wonder if they could have left a little space for internal cooling though. I like the idea of replacing the batteries with longer ones for the 600 and 1000 mile options, but I do wonder if the longer batteries will conduct heat to the baee as well. And if they go with 100 kW charging the excess heat during charging will be much greater. I think Aptera is assuming that end cooling will work just fine, and testing will prove that it's overengineered enough that they can handle even more heat with just a bigger cooling system. But if they have to redesign the battery pack it will take time, and the while point was to reuse the battery pack. Of course, rhe new battery pack can be used in the original 400 mile version. So they could save some money that way.

Thought we were going to watch it and THEN talk about it...

You input 384.

The WSJ did a hit piece and I consider this to be lazy journalism. They could have made this a compare & contrast article - presented just like you did, summing up the article with the likelihood of any startup actually succeeding.

Nice review of two companies using Crowdfunding. Boxable definitely has signs if a money siphon, whereas Aptera is not, based on founder salaries & bonuses. Surely the SEC could reduce scams by imposing limits of CEO compensation. Average living expenses, exclusion of bonuses, or at least production based milestone bonuses (like Tesla) could go a long way to prevent ripoffs. The fact this does not exist means the SEC doesn’t really care.

I agree, the design is good. I agree on the thermal testing, that's as important as the vibration testing, especially for battery packs, and possibly complete the vibration tests after many cycles which may have degraded the welds on the bus bars. But there's only so much testing you can do in a lab. Let's not lose sight of the fact that the PI builds are in fact testbeds themselves. Making the product with parts as close as possible to production gives the best real world testing solution. Driving those vehicles is the proving, and then you make further adjustments. The refinement process is what makes a truly quality product in this case, and we're just sort of starting that process with the PI builds. I'm interested to see what results from these builds.

The battery tray will likely be constructed from extruded aluminum cross members joined at their ends either by direct welding or some other custom cast or extruded members. I beleive that is what Chris said was happening in your interview with him previously, I may be mistaken though cause he could have been referring to the frame at that point.

Good breakdown and look into the battery module details Steve, thank you!

If this car charges at 400 Mi/h that means the peak charging speed must be only 50 kilowatts

400 mi per hour charge rate doesn't seem that great. That is a 1C charge rate and 1 hour to fast charge from empty to full when on the road for the launch edition vehicles. I would have thought they would have been able to charge at 2-3C for a 30-40 min charge. Hopefully that will improve when the PI vehicles come out.

Thanks

The tabs are not perfectly positioned. Hopefully still within tolerance.

Nasty math class flashbacks aside, very nice informative cast, Steve. Thanks.

Legacy investors hate retail investors. The Wall Street Journal is written for legacy investors

I can't get enough Aptera content. Thanks Steve!

I wonder if thermal compound is the same as the thermal paste they use on CPUs.

Battery sizes, I can't say for sure but the zero on the end is actually the letter O. It signifies that the cell is round. I kinda wish they would drop that because it's not necessary and confusing.

Loving the detailed reviews of the Aptera news.

Good recap.. but wondering why Aptera doesn't use [Corrected: I incorrectly siad LiPo when I meant litium Iron... my bad on the acronym] LiFePo instead of nickel/cobalt chemistries? the aluminum battery pack holder looks CNC machined, not very cost effective. Wonder what their end game production line method will be to manufacture.

Little late in the game for battery validation don’t you think? How is that cooled with no channels or coolant contact areas?

So no ctns battery, no elaphe motors, no belly pan cooling Yeah, sure

Hi Steve!!

I'll be waiting for SUNA to ring the opening bell on the NASDAQ

Note he said they have their work cut out to deliver the usa vehicles........he should have said we have our work cut out to produce them, not deliver them......its subtle play on words

He was saying the same thing in 2007....see ref (2) at bottom of aptera wikipedia page. Company started in 2005....next year will be the 20th anniversary of Aptera.....without one vehicle produced for market

I found a very early video of Steve Fambro saying he got obsessed with the design ( this is way way back pre X-prize days ( 2006?)....that is something very typical of scientists, obsession can be a positive thing and often is what is needed to get results in the long term. Especially in science/technology. There is a down side too, if your going down a path that is not going to be successful you have to, at some stage, pull the plug. If your obsessed its almost impossible to pull the plug. I have nothing but admiration for what they have achieved so far, I really hope they have success in getting the vehicle into production. There are a few issues: 1.honesty in interviews........100% honesty is required not avoiding questions 2. tricky issue: at what point should they give up is success is not going to happen? Since there have been production dates being given going back 16 years or so, which have never materialised , is there a point at which they should say "we tried hard but its just not going to happen". This is the dilemma. Is it a rabbit hole ( money pit) with no end?

I am in Mobile Alabama, and met one of the other accelerators in Fairhope Alabama at last year's Earth day event. He was doing a show and tell with several Teslas and a chevy bolt. I think two of the cars were his, the others were lent to him for the event.

I think a lot of investors are former collegiate solar car team members who remember how these things cost like 10 mil and took 4+ years to make one. I think a lot of us know that it sucks to make a solar car, and that's why we invest. It might not work out, the two other solar car companies are already bankrupt, but isn't that going to be a great experience for those engineers lucky enough to work on this? And if they pull it off isn't it going to be sick as hell.

Another way to tremendously increase credibility: Offer each reservation owner a sales invoice contract of price and performance with a late delivery discount penalty. I bet Aptera won't do it!

I would change the question to: if Aptera does well, will the crowdfunding crowd share fairly in the winnings?

I wonder if many Capital Global employees read Wallstreet Journal? It's this simple: No confirmation of miles/kWh, kWh/day, price, cooling, etc. Then comes schedule failures.
