SpaceX is installing Tesla battery packs on its Starship MK1 rocket prototype
First noticed by NASASpaceflight.com forum member “exilon”, SpaceX appears to have selected off-the-shelf Tesla battery packs as the power storage method of choice for its Starship Mk1 prototype, currently in the midst of a busy period of integration
Potentially taken directly from Tesla Model S/X powertrains otherwise headed for recycling, SpaceX technicians have spent the last 24 or so hours attaching numerous battery packs to part of a Starship subsystem known as header tanks. This is the latest addition to SpaceX and Tesla’s relatively close relationship – the two have begun to work together to solve challenges with materials science, batteries, and more within the last 12-24 months.
While initially surprising, the appearance of battery packs quite literally taken from Tesla Model S/X vehicles or their Gigafactory assembly line actually makes a lot of sense. By using prepackaged, off-the-shelf battery systems with industry-leading power management capabilities, SpaceX is probably saving a huge amount of time, money, and effort. If the battery packs were already nearing the end of their useful automotive lives, the net cost could very well approach zero, aside from what looks like a minimal mounting brace. It’s possible that SpaceX has even pursued modifying and certifying large Tesla-derived battery packs for use on orbital Starship missions.
These battery packs were spotted by an eagle-eyed forum user who was first to recognize the hardware for what it likely was. Per the above photo, SpaceX appears to have joined two self-contained Tesla battery packs into single units that were then installed on a header tank. Knowing that the highest capacity Tesla offers is ~100 kWh, the 2×2 packs could store up to 400 kWh and offer instantaneous power output (ignoring thermal limitations) well into the megawatt (MW) range. It’s unclear if the first header tank also had batteries attached but SpaceX technicians began installing that tank inside Starship’s nose cone on the evening September 22nd. Tank #2 will likely follow in the next 24 hours per Musk’s indication that Starship Mk1 would be stacked to its full height on Wednesday.
For unknown reasons, SpaceX is choosing to mount the ~1000 kg (2200 lb) battery pack pairs directly onto the outside of one of Starship Mk1’s two header tanks. These tanks compliment the rocket prototype’s main propellant tanks and are meant to serve as small reserves of fuel (methane) and oxidizer (oxygen) that can be pressurized independently. During dramatic in-space and in-atmosphere maneuvers, the g-forces exerted on Starship could easily find the vehicle’s propellant pushed away from the ‘bottom’ of its main tanks, creating bubbles or voids that can damage and destroy rocket engines if ingested.
Pressurizing the entirety of the main tanks (a cylinder measuring 9m by ~40m or 30×130 ft) is extremely impractical – hence the need for much smaller header tanks. Falcon 9 boosters are able to sidestep this issue because they are small and light enough (relatively speaking) that cold gas thrusters can efficiently generate the positive Gs needed to safely ignite its engines for recovery and landing maneuvers. Empty, Starship alone will likely weigh no less than 4-6 times as much as a Falcon 9 booster (~25 tons, 55,000 lb).
According to CEO Elon Musk, SpaceX has decided to install those header tanks in the very tip of Starship Mk1’s conical nose to help balance out the vehicle’s center of mass. As a side-effect, SpaceX will have to install feed lines that run the entire length of the spacecraft and protect them with steel aero-covers. It’s unclear if this design choice is necessitated by Starship’s early, prototypical form or if – once outfitted with crew quarters or a functional cargo bay – it’s possible that that added mass will serve as enough of a counterbalance to preclude the need for ballast in the nose.
Musk posted a view inside an adjacent SpaceX fabrication facility in Boca Chica on September 23rd, showing a large row of staged steel sheets that will eventually be formed into aerodynamic shrouds for Starship Mk1’s raceways, fins, and wings.

Swedish union rep pissed that Tesla is working around a postal blockade they started
Tesla Sweden is now using dozens of private residences as a way to obtain license plates for its vehicles.
Two years into their postal blockade, Swedish unions are outraged that Tesla is still able to provide its customers’ vehicles with valid plates through various clever workarounds.
Seko chairman Gabriella Lavecchia called it “embarrassing” that the world’s largest EV maker, owned by CEO Elon Musk, refuses to simply roll over and accept the unions’ demands.
Unions shocked Tesla won’t just roll over and surrender
The postal unions’ blockade began in November 2023 when Seko and IF Metall-linked unions stopped all mail to Tesla sites to force a collective agreement. License plates for Tesla vehicles instantly became the perfect pressure point, as noted in a Dagens Arbete report.
Tesla responded by implementing initiatives to work around the blockades. A recent investigation from Arbetet revealed that Tesla Sweden is now using dozens of private residences, including one employee’s parents’ house in Trångsund and a customer-relations staffer’s home in Vårby, as a way to obtain license plates for its vehicles.
Seko chairman Gabriella Lavecchia is not pleased that Tesla Sweden is working around the unions’ efforts yet again. “It is embarrassing that one of the world’s largest car companies, owned by one of the world’s richest people, has sunk this low,” she told the outlet. “Unfortunately, it is completely frivolous that such a large company conducts business in this way.”
-->Two years on and plates are still being received
The Swedish Transport Agency has confirmed Tesla is still using several different workarounds to overcome the unions’ blockades.
As noted by DA, Tesla Sweden previously used different addresses to receive its license plates. At one point, the electric vehicle maker used addresses for car care shops. Tesla Sweden reportedly used this strategy in Östermalm in Stockholm, as well as in Norrköping and Gothenburg.
Another strategy that Tesla Sweden reportedly implemented involved replacement plates being ordered by private individuals when vehicles change hands from Tesla to car buyers. There have also been cases where the police have reportedly issued temporary plates to Tesla vehicles.

Czech Deputy excited for Tesla FSD, hints at Transport Committee review
The ANO party lawmaker shared his thoughts about FSD in a post on social media platform X.
Martin Kolovratník, a Czech Republic Chamber of Deputies member, has expressed his excitement for Tesla’s Full Self-Driving (FSD) after an apparent constituent called for a quick approval for the advanced safety system.
The ANO party lawmaker, who drives both diesel and EV, shared his thoughts about the matter in a post on social media platform X.
The official’s initial statements
Kolovratník kicked off the exchange with a post outlining his coalition’s efforts to scrap highway toll exemptions for electric vehicles and plug-ins starting in 2027.
“Times have changed. Electric vehicles are no longer a fringe technology, but a full-fledged part of operations. And if someone uses the highway network, they should follow the same rules as everyone else. That’s the basis of fairness,” he wrote.
He emphasized equity over ideology, noting his personal mix of diesel and electric driving. “For this reason, there is no reason to continue favoring one technology at the expense of another… It’s not about ideology, it’s about equal conditions. That’s why we clearly agreed within the new coalition: the exemption for electric vehicles and plug-ins will end in 2027. The decision is predictable, understandable, and economically sound.”
-->Tesla FSD enthusiasm
The conversation pivoted to Tesla’s FSD when X user @robotinreallife, who seems to be one of the official’s constituents, replied that other matters are more important than ending highway exemptions for EVs.
“I’m happy to pay for the highway, but I have a question about a much more fundamental matter: The Netherlands will approve the operation of Tesla FSD in February 26, a technology that has been proven to reduce accidents. The Czech Republic has the option to immediately recognize this certification. Do you plan to support this step so that we don’t unnecessarily delay?” the X user asked.
Kolovratník responded promptly, sharing his own excitement for the upcoming rollout of FSD. “I know about it. I like it and it seems interesting to me. Once we set up the committees and subcommittees, we’ll open it right away in that transport one. Thanks for the tip, I’ll deliver the report,” the official noted in his reply on X.
Kolovratník’s nod to FSD hints at the system’s potentially smooth rollout to Czechia in the coming year. With the Netherlands possibly greenlighting FSD (Supervised) in early 2026, Kolovratník’s commitment could accelerate cross-border certification, boosting FSD’s foray into Europe by a notable margin.

Tesla Model 3 named New Zealand’s best passenger car of 2025
Tesla flipped the switch on Full Self-Driving (Supervised) in September, turning every Model 3 and Model Y into New Zealand’s most advanced production car overnight.
The refreshed Tesla Model 3 has won the DRIVEN Car Guide AA Insurance NZ Car of the Year 2025 award in the Passenger Car category, beating all traditional and electric rivals.
Judges praised the all-electric sedan’s driving dynamics, value-packed EV tech, and the game-changing addition of Full Self-Driving (Supervised) that went live in New Zealand this September.
Why the Model 3 clinched the crown
DRIVEN admitted they were late to the “Highland” party because the updated sedan arrived in New Zealand as a 2024 model, just before the new Model Y stole the headlines. Yet two things forced a re-evaluation this year.
First, experiencing the new Model Y reminded testers how many big upgrades originated in the Model 3, such as the smoother ride, quieter cabin, ventilated seats, rear touchscreen, and stalk-less minimalist interior. Second, and far more importantly, Tesla flipped the switch on Full Self-Driving (Supervised) in September, turning every Model 3 and Model Y into New Zealand’s most advanced production car overnight.
FSD changes everything for Kiwi buyers
The publication called the entry-level rear-wheel-drive version “good to drive and represents a lot of EV technology for the money,” but highlighted that FSD elevates it into another league. “Make no mistake, despite the ‘Supervised’ bit in the name that requires you to remain ready to take control, it’s autonomous and very capable in some surprisingly tricky scenarios,” the review stated.
-->At NZ$11,400, FSD is far from cheap, but Tesla also offers FSD (Supervised) on a $159 monthly subscription, making the tech accessible without the full upfront investment. That’s a game-changer, as it allows users to access the company’s most advanced system without forking over a huge amount of money.
