Tesla teardown expert Sandy Munro recently recreated what he believes will be the new 4680 Battery Pack by recreating the cell housing unit for a new video. Munro is an extremely familiar figure to Tesla fans as he spent some time breaking down both the Model 3 sedan and, more recently, the Model Y crossover. However, the design expert, along with his team of highly-qualified engineers, composed a copy of the 4680 cell pack, which will be used in future Tesla models to increase power, energy, and range.

Munro admits that this may not be exactly what Tesla will use in its future vehicles, but this could likely be extremely similar to what the electric automaker will introduce. For those that aren’t familiar, the Model 3 and Model Y previously used Tesla’s 2170 cells, which were able to provide superior performance compared to the 18650 cells that were used in the Model S and Model X. However, the electric automaker had been working with Jeff Dahn and other researchers at Dalhousie University in Canada to develop new, revolutionary cells that would provide longer lifespans with more power and more energy.

Interestingly, these cells with higher performance would dramatically decrease Tesla’s cars’ cost, as the materials they used would be easier to obtain and cheaper to produce. Creating a more efficient and cost-effective battery cell was the main strategy in having Tesla’s vehicles comparable with gas cars in terms of cost.

Tesla uses 4,416 2170 cells in the Model Y, but this number is significantly lower with the 4680 cells due to their larger size, which carries significantly more energy and power than the previous cell. Munro states that only 960 cells will be used in the new battery pack, and with the increases in range, power, and energy, Tesla is truly onto something remarkable that will only increase their lead in the EV sector.

“We are focusing our attention on this, which is so much better than what they had with the 2170,” Munro said.

Tesla rolled out the new 4680 cell at its highly-anticipated Battery Day event on September 22nd. CEO Elon Musk summarized Tesla’s plan to begin building a more affordable battery cell, ultimately leading to a more affordable vehicle. In summation, Tesla plans to decrease the cost of cell manufacturing by a significant amount and decrease the cost of money per kilowatt-hour by up to 56% through design, production efficiencies, and material sourcing.

One of Tesla’s biggest advantages in designing its own cells and packs is that it can significantly reduce costs while also increasing the ability to fix issues when they occur. One of the strategies with its battery cells from the very beginning was to individualize each cell so it was easier be traced and replaced if any issues were to occur. Teslarati covered a recent replacement of a Model S battery cell showed the process for fixing a pack when a cell goes awry.

The new 4680 cells have been used for several months, Elon Musk said in an interview earlier this year. However, not all vehicles utilize the new cells as the Kato Road cell production facility near Tesla’s Fremont factory is not producing enough yet. However, the increased production will eventually lead to Tesla using the 4680 batteries exclusively within its cars, which will lead to higher range ratings and increased performance specs, making Tesla’s EVs even more superior to its competitors.

Munro’s full 4680 pack breakdown is available below.

Tesla China recorded 20,680 domestic insurance registrations during the week of June 23–29, marking its highest weekly total in the second quarter of 2025. 

The figure represents a 49.3% increase from the previous week and a 46.7% improvement year-over-year, suggesting growing domestic momentum for the electric vehicle maker in Q2’s final weeks.

Q2 closes with a boost despite year-on-year dip

The strong week helped lift Tesla’s performance for the quarter, though Q2 totals remain down 4.6% quarter-over-quarter and 10.9% year-over-year, according to industry watchers. Despite these declines, the last week of June stands as the second-highest of 2025 and the best-performing week of the quarter. 

As per industry watchers, Tesla China delivered 15,210 New Model Y units last week, the highest weekly tally since the vehicle’s launch. The Model 3 followed with 5,470 deliveries during the same period. Tesla’s full June and Q2 sales data for China are expected to be released by the China Passenger Car Association (CPCA) in the coming days.

Tesla China and minor Model 3 and Model Y updates

Tesla manufactures the Model 3 and Model Y at its Shanghai facility, which provides vehicles to both domestic and international markets. In May, the automaker reported 38,588 retail sales in China, down 30.1% year-over-year but up 34.3% from April. Exports from Shanghai totaled 23,074 units in May, a 32.9% improvement from the previous year but down 22.4% month-over-month, as noted in a CNEV Post report.

Earlier this week, Tesla introduced minor updates to the long-range versions of the Model 3 and Model Y in China. The refreshed Model 3 saw a modest price increase, while pricing for the updated Model Y Long Range variant remained unchanged. These adjustments come as Tesla continues refining its China lineup amid shifting local demand and increased competition from domestic brands.

Tesla investors will be shocked by Jim Cramer’s latest assessment

Jim Cramer is now speaking positively about Tesla, especially in terms of its Robotaxi performance and its perception as a company.

Tesla investors will be shocked by analyst Jim Cramer’s latest assessment of the company.

When it comes to Tesla analysts, many of them are consistent. The bulls usually stay the bulls, and the bears usually stay the bears. The notable analysts on each side are Dan Ives and Adam Jonas for the bulls, and Gordon Johnson for the bears.

Jim Cramer is one analyst who does not necessarily fit this mold. Cramer, who hosts CNBC’s Mad Money, has switched his opinion on Tesla stock (NASDAQ: TSLA) many times.

He has been bullish, like he was when he said the stock was a “sleeping giant” two years ago, and he has been bearish, like he was when he said there was “nothing magnificent” about the company just a few months ago.

Now, he is back to being a bull.

Cramer’s comments were related to two key points: how NVIDIA CEO Jensen Huang describes Tesla after working closely with the Company through their transactions, and how it is not a car company, as well as the recent launch of the Robotaxi fleet.

Jensen Huang’s Tesla Narrative

Cramer says that the narrative on quarterly and annual deliveries is overblown, and those who continue to worry about Tesla’s performance on that metric are misled.

“It’s not a car company,” he said.

He went on to say that people like Huang speak highly of Tesla, and that should be enough to deter any true skepticism:

“I believe what Musk says cause Musk is working with Jensen and Jensen’s telling me what’s happening on the other side is pretty amazing.”

Tesla self-driving development gets huge compliment from NVIDIA CEO

Robotaxi Launch

Many media outlets are being extremely negative regarding the early rollout of Tesla’s Robotaxi platform in Austin, Texas.

There have been a handful of small issues, but nothing significant. Cramer says that humans make mistakes in vehicles too, yet, when Tesla’s test phase of the Robotaxi does it, it’s front page news and needs to be magnified.

He said:

“Look, I mean, drivers make mistakes all the time. Why should we hold Tesla to a standard where there can be no mistakes?”

It’s refreshing to hear Cramer speak logically about the Robotaxi fleet, as Tesla has taken every measure to ensure there are no mishaps. There are safety monitors in the passenger seat, and the area of travel is limited, confined to a small number of people.

Tesla is still improving and hopes to remove teleoperators and safety monitors slowly, as CEO Elon Musk said more freedom could be granted within one or two months.

Tesla has over 70,000 Superchargers worldwide. It is the most expansive and robust EV charging network in the world. It’s the main reason why so many companies have chosen to adopt Tesla’s charging connector in North America and Europe.

In China, some EVs can use Tesla Superchargers as well.

The V4 Supercharger is capable of charging vehicles at speeds of up to 325kW for vehicles in North America. This equates to over 1,000 miles per hour of charging.
