The Tesla Model 3’s battery pack was given a partial teardown treatment recently, thanks to the efforts of automotive veteran Jack Rickard and his team at EVTV. Rickard, a car enthusiast who conducts electric vehicle conversions, was ultimately impressed with how the Model 3’s battery was assembled, as well as the refinement of its design.

Rickard’s team was able to acquire the battery pack from a totaled Model 3. Upon removing the pack from the vehicle, the electric car conversion specialist’s interest was piqued by the covering of the battery modules. According to Rickard, the sections of the battery pack directly above the Model 3’s 2170 cells had a thin pad that was strangely wet.

This particular section mentioned by Rickard appear to be the “fluff” that Elon Musk mentioned during Tesla’s Q1 2018 earnings call. According to Musk, the fiberglass mats, which are placed on top of the battery pack, became one of the scenarios that proved human hands can work better than robots.

“They’re basically fluff. We tried to automate the placement and bonding of fluff to the top of the battery pack, which was ridiculous. ‘Flufferbot,’ which was really an incredibly difficult machine to make work. Machines are not good at picking up pieces of fluff. Hands are way better at doing that,” Musk said.

Another particularly compelling observation highlighted by Rickard was that the four modules of the Model 3 battery pack were not identical, with two modules featuring 25 cell groups in series and the other two featuring 23 cell groups in series. Rickard’s team did not tear down the battery packs down to its individual 2170 cells, but it was mentioned that each one of the cell groups includes 46 2170 cells that are connected in parallel. Overall, the vehicle appears to have a total of 4,416 2170 cells, at least for the Model 3’s long-range RWD configuration.

The Model 3’s battery weighs 1,054 pounds, which, according to the group, places the energy density of the pack at around 168 Wh/kg. The individual modules of the Model 3 battery are lined with a ribbon-like circuit that goes across the top of the modules and into a BMS board. The BMS boards are sub-boards that are installed on each module, and are, in turn, connected to a main board using only two pins.

Ultimately, the EVTV team was impressed with the Model 3’s battery, with Rickard even dubbing it as the “best battery ever built to date.” The electric car conversion specialist also noted that the Model 3 battery would likely be a favorite among the DIY community. Considering that Tesla is attempting to achieve a production rate of 5,000 Model 3 per week by the end of Q2 2018, Rickard noted that the electric car’s batteries would probably be abundant in the market. This bodes well for DIY enthusiasts like Rickard, who could utilize the modules as batteries for RVs, home battery units, and electric car conversions, among other projects.

Jack Rickard and his team’s observations about the Model 3’s battery are in line with the findings of Sandy Munro during his firm’s teardown of the vehicle. In a recent episode of Autoline After Hours, Munro dubbed the Model 3’s pack as the best in the industry, noting the .2 milliamp differential between each of the battery blocks.

“Nobody can balance batteries that close. Nobody. Nobody’s ever done that,” Munro said.

SpaceX used the Super Bowl broadcast to promote Starlink, pitching the service as fast, affordable broadband available across much of the world.

The advertisement highlighted Starlink’s global coverage and emphasized simplified customer onboarding, stating that users can sign up for service in minutes through the company’s website or by phone in the United States.

The campaign comes as SpaceX accelerates Starlink’s commercial expansion. The satellite internet service grew its global user base in 2025 to over 9 million subscribers and entered several dozen additional markets, as per company statements.

Starlink growth and momentum

Starlink has seen notable success in numerous regions across the globe. Brazil, in particular, has become one of Starlink’s largest growth regions, recently surpassing one million users, as per Ookla data. The company has also expanded beyond residential broadband into aviation connectivity and its emerging direct-to-cellular service.

Starlink has recently offered aggressive promotions in select regions, including discounted or free hardware, waived installation fees, and reduced monthly pricing. Some regions even include free Starlink Mini for select subscribers. In parallel, SpaceX has introduced AI-driven tools to streamline customer sign-ups and service selection.

The Super Bowl appearance hints at a notable shift for Starlink, which previously relied largely on organic growth and enterprise contracts. The ad suggests SpaceX is positioning Starlink as a mainstream alternative to traditional broadband providers.

Tesla engineers deflected calls from this tech giant’s now-defunct EV project

Tesla engineers deflected calls from Apple on a daily basis while the tech giant was developing its now-defunct electric vehicle program, which was known as “Project Titan.”

Back in 2022 and 2023, Apple was developing an EV in a top-secret internal fashion, hoping to launch it by 2028 with a fully autonomous driving suite.

However, Apple bailed on the project in early 2024, as Project Titan abandoned the project in an email to over 2,000 employees. The company had backtracked its expectations for the vehicle on several occasions, initially hoping to launch it with no human driving controls and only with an autonomous driving suite.

Apple canceling its EV has drawn a wide array of reactions across tech

It then planned for a 2028 launch with “limited autonomous driving.” But it seemed to be a bit of a concession at that point; Apple was not prepared to take on industry giants like Tesla.

Wedbush’s Dan Ives noted in a communication to investors that, “The writing was on the wall for Apple with a much different EV landscape forming that would have made this an uphill battle. Most of these Project Titan engineers are now all focused on AI at Apple, which is the right move.”

Apple did all it could to develop a competitive EV that would attract car buyers, including attempting to poach top talent from Tesla.

In a new podcast interview with Tesla CEO Elon Musk, it was revealed that Apple had been calling Tesla engineers nonstop during its development of the now-defunct project. Musk said the engineers “just unplugged their phones.”

Musk said in full:

“They were carpet bombing Tesla with recruiting calls. Engineers just unplugged their phones. Their opening offer without any interview would be double the compensation at Tesla.”

Interestingly, Apple had acquired some ex-Tesla employees for its project, like Senior Director of Engineering Dr. Michael Schwekutsch, who eventually left for Archer Aviation.

Tesla took no legal action against Apple for attempting to poach its employees, as it has with other companies. It came after EV rival Rivian in mid-2020, after stating an “alarming pattern” of poaching employees was noticed.

Tesla to a $100T market cap? Elon Musk’s response may shock you

Published

tesla elon musk

There are a lot of Tesla bulls out there who have astronomical expectations for the company, especially as its arm of reach has gone well past automotive and energy and entered artificial intelligence and robotics.

However, some of the most bullish Tesla investors believe the company could become worth $100 trillion, and CEO Elon Musk does not believe that number is completely out of the question, even if it sounds almost ridiculous.

To put that number into perspective, the top ten most valuable companies in the world — NVIDIA, Apple, Alphabet, Microsoft, Amazon, TSMC, Meta, Saudi Aramco, Broadcom, and Tesla — are worth roughly $26 trillion.

Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI

Cathie Wood of ARK Invest believes the number is reasonable considering Tesla’s long-reaching industry ambitions:

“…in the world of AI, what do you have to have to win? You have to have proprietary data, and think about all the proprietary data he has, different kinds of proprietary data. Tesla, the language of the road; Neuralink, multiomics data; nobody else has that data. X, nobody else has that data either. I could see $100 trillion. I think it’s going to happen because of convergence. I think Tesla is the leading candidate [for $100 trillion] for the reason I just said.”

Musk said late last year that all of his companies seem to be “heading toward convergence,” and it’s started to come to fruition. Tesla invested in xAI, as revealed in its Q4 Earnings Shareholder Deck, and SpaceX recently acquired xAI, marking the first step in the potential for a massive umbrella of companies under Musk’s watch.

SpaceX officially acquires xAI, merging rockets with AI expertise

Now that it is happening, it seems Musk is even more enthusiastic about a massive valuation that would swell to nearly four-times the value of the top ten most valuable companies in the world currently, as he said on X, the idea of a $100 trillion valuation is “not impossible.”

Tesla is not just a car company. With its many projects, including the launch of Robotaxi, the progress of the Optimus robot, and its AI ambitions, it has the potential to continue gaining value at an accelerating rate.

Musk’s comments show his confidence in Tesla’s numerous projects, especially as some begin to mature and some head toward their initial stages.
