Tesla Model 3 battery details revealed in partial teardown and analysis
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.

Tesla (NASDAQ: TSLA) stock received a price target update from Pierre Ferragu of Wall Street firm New Street Research, citing the company’s growing lead in self-driving and autonomy.
On Tuesday, Ferragu bumped his price target from $520 to $600, stating that the consensus from the Consumer Electronics Show in Las Vegas was that Tesla’s lead in autonomy has been sustained, is growing, and sits at a multiple-year lead over its competitors.
CES 2026 validates Tesla’s FSD strategy, but there’s a big lag for rivals: analyst
“The signal from Vegas is loud and clear,” the analyst writes. “The industry isn’t catching up to Tesla; it is actively validating Tesla’s strategy…just with a 12-year lag.”
The note shows that the company’s prowess in vehicle autonomy is being solidified by lagging competitors that claim to have the best method. The only problem is that Tesla’s Vision-based approach, which it adopted back in 2022 with the Model 3 and Model Y initially, has been proven to be more effective than competitors’ approach, which utilizes other technology, such as LiDAR and sensors.
Currently, Tesla shares are sitting at around $433, as the company’s stock price closed at $432.96 on Tuesday afternoon.
Ferragu’s consensus on Tesla shares echoes that of other Wall Street analysts who are bullish on the company’s stock and position within the AI, autonomy, and robotics sector.
Dan Ives of Wedbush wrote in a note in mid-December that he anticipates Tesla having a massive 2026, and could reach a $3 trillion valuation this year, especially with the “AI chapter” taking hold of the narrative at the company.
Ives also said that the big step in the right direction for Tesla will be initiating production of the Cybercab, as well as expanding on the Robotaxi program through the next 12 months:
“…as full-scale volume production begins with the autonomous and robotics roadmap…The company has started to test the all-important Cybercab in Austin over the past few weeks, which is an incremental step towards launching in 2026 with important volume production of Cybercabs starting in April/May, which remains the golden goose in unlocking TSLA’s AI valuation.”
Tesla analyst breaks down delivery report: ‘A step in the right direction’
Tesla has transitioned from an automaker to a full-fledged AI company, and its Robotaxi and Cybercab programs, fueled by the Full Self-Driving suite, are leading the charge moving forward. In 2026, there are major goals the company has outlined. The first is removing Safety Drivers from vehicles in Austin, Texas, one of the areas where it operates a ride-hailing service within the U.S.
Ultimately, Tesla will aim to launch a Level 5 autonomy suite to the public in the coming years.

Elon Musk appeared on the Moonshots podcast with Peter Diamandis today to discuss AGI, U.S. vs. China, Tesla, and some other interesting topics, but there was some discussion about the upcoming unveiling of the Roadster, the company’s electric supercar that will arrive several years after it was initially slated for release.
Musk made some pretty amazing claims about the Roadster; we already know it is supposed to be lightning-fast and could even hover, if Tesla gets everything to happen the way it wants to. However, the car has some pretty crazy capabilities, some of which have not even been revealed.
On the podcast, Musk said:
“This is not a…safety is not the main goal. If you buy a Ferrari, safety is not the number one goal. I say, if safety is your number one goal, do not buy the Roadster…We’ll aspire not to kill anyone in this car. It’ll be the best of the last of the human-driven cars. The best of the last.”
🚨 Elon on the Roadster unveiling, scheduled for April 1:

Musk makes a good point: people who buy expensive sports cars with ridiculous top speeds and acceleration rates do not buy them to be safe. They hope they are safe in case of an emergency or crash, but safety is not at the forefront of their thoughts, because nobody buys a car thinking they’ll crash it.
The Roadster is truly going to push the limits and capabilities of passenger vehicles; there’s no doubt about that. Tesla plans to show off the new version car for the first time on April 1, and Musk has only hinted at what is possible with it.
Musk said back in November:
“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveiling ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”
Production is set to begin between 12 and 18 months after the unveiling, which would put the car out sometime in 2027. Hopefully, Tesla is able to stay on track with the scheduling of the Roadster; many people have been waiting a long time for it.
