Tesla Model S Plaid battery pack shows that 18650 cell innovations are not over yet
A picture of the Tesla Model S Plaid’s 18650 battery pack with its modules visible was recently shared online. The image hinted that Tesla is still in the process of optimizing and innovating its 18650 battery technology, despite the cells being quite a bit long in the tooth.
Tesla is constantly trying to improve its battery technology, which has led to the development of the company’s highly-anticipated 4680 cells. The 4680 cells are expected to be used in vehicles that require a lot of power such as the Semi, Cybertruck, and new Roadster. Amidst the ongoing supply chain challenges and delays in the mass production of 4680 cells from Tesla’s Kato Road facility, however, the company noted that the Model S Plaid, its current flagship sedan, will maintain its use of 18650 batteries.
According to Redditor u/punx, who posted the picture, the Model S Plaid’s battery pack features five large modules, packed to the brim with Panasonic’s 18650 cells. The Reddit user confirmed the cells were 18650 with measurements proving they were 18mm in diameter and 65mm in length. Previous iterations of the Model S have battery packs with as many as 16 individual modules.
A decrease in the number of modules in the Model S Plaid’s battery means fewer parts for the vehicle’s pack, resulting in lower production costs for Tesla. Lowering production costs for its vehicles is a key priority for the company. At the 2021 Annual Shareholders Meeting, Elon Musk mentioned that Tesla has been making a lot of progress in cost reduction, despite the average selling price going down due to the lower prices of vehicles like the Model 3 and Model Y.
“We managed to still do decently well on a gross margin. So, you know, getting the average price down and gross margin up is very difficult,” Musk pointed out. “But we’ve managed to do that. Our goal is really to make the cars as affordable as possible.”
The Model S Plaid (and perhaps the Model X Plaid) might be the last vehicles in Tesla’s lineup that would use 18650 cells. With Tesla focusing its efforts to master the mass production of its 4680 cells — which are more powerful and cheaper to produce — it would not be a surprise if future iterations of the flagship sedan and SUV are fitted with 4680 structural batteries. The 18650 cells are showing their age, after all, as Tesla has been using them since the days of the original Roadster.
If Tesla does utilize its 4680 cells for the Model S and Model X, the vehicles would likely be equipped with nickel-based batteries. The Tesla CEO has previously explained that the supply chain goes all the way back to raw materials like lithium and nickel, which are used to develop the company’s battery cells. During the last earnings call, Elon Musk mulled over the idea of Tesla consolidating its battery offerings down to 2 or 3 form factors, one nickel-based for high-powered vehicles like the Semi and the other iron-based for mass-produced cars like the Model 3.
“So right now, we kind of have the Baskin Robbins of batteries situation, where there’s so many formats and so many chemistries, that it’s like we’ve got like 36 flavors of battery at this point,” Musk said.
“This results in an engineering drag coefficient where each variants of cell chemistry and format requires as certain amount of engineering to maintain it and troubleshoot. And this inhibits our forward progress. So it is going to be important to consolidate to maybe—ideally two form factors, maybe three, but ideally two. And then just one nickel chemistry and one iron chemistry, so we don’t have to troubleshoot so many different variants,” he said.
With Tesla likely retiring its 18650 cells in the future, the Model S Plaid’s five-module battery pack could be seen as one of the final iterations of the technology that the company quite literally used to build its empire. And considering that the 18650 cells are being used in the Model S Plaid, there is no better swan song for the humble batteries.

Elon Musk hints Tesla investors will be rewarded heavily
“Hold onto your Tesla stock. It’s going to be worth a lot, I think. That’s my bet,” Musk said.
Elon Musk recently hinted that he believes Tesla investors will be rewarded heavily if they continue to hold onto their shares, and he reiterated that in a new interview that the company released on its social accounts this week.
Musk is one of the most successful CEOs in the modern era and has mammothed competitors on the Forbes Net Worth List over the past year as his holdings in his various companies have continued to swell.
Tesla investors, especially those who have been holding shares for several years, have also felt substantial gains in their portfolios. Over the past five years, the stock is up over 78 percent. Since February 2019, nearly seven years ago to the day, the stock is up over 1,800 percent.
Musk said in the interview:
“Hold onto your Tesla stock. It’s going to be worth a lot, I think. That’s my bet.”

It’s no secret Musk has been extremely bullish on his own companies, but Tesla in particular, because it is publicly traded.
However, the company has so many amazing projects that have an opportunity to revolutionize their respective industries. There is certainly a path to major growth on Wall Street for Tesla through its various future projects, including Optimus, Cybercab, Semi, and Unsupervised FSD.
- Optimus (Tesla’s humanoid robot): Musk has discussed its potential for tasks like childcare, walking dogs, or assisting elderly parents, positioning it as a massive long-term driver of company value.
- Cybercab (Tesla’s robotaxi/autonomous ride-hailing vehicle): a fully autonomous vehicle geared specifically for Tesla’s ride-sharing ambitions.
- Semi (Tesla’s electric truck, with mentions of expansion, like in Europe): brings Tesla into the commercial logistics sector.
- Unsupervised FSD (Full Self-Driving software achieving full autonomy without human supervision): turns every Tesla owner’s vehicle into a fully-autonomous vehicle upon release
These projects specifically are some of the highest-growth pillars Tesla has ever attempted to develop, especially in Musk’s eyes, as he has said Optimus will be the best-selling product of all-time.
Many analysts agree, but the bullish ones, like Cathie Wood of ARK Invest, are perhaps the one who believes Tesla has incredible potential on Wall Street, predicting a $2,600 price target for 2030, but this is not even including Optimus.
She told Bloomberg last March that she believes that the project will present a potential additive if Tesla can scale faster than anticipated.

Just three days ago, the initial delivery date of June 2026 was pushed back to early Fall, and now, that date has officially moved to April 2027.
The fact that Tesla has had to push back deliveries once again proves one of two things: either Tesla has slow production plans for the new Cybertruck trim, or demand is off the charts.
Judging by how Tesla is already planning to raise the price based on demand in just a few days, it seems like the company knows it is giving a tremendous deal on this spec of Cybertruck, and units are moving quickly.
That points more toward demand and not necessarily to slower production plans, but it is not confirmed.
Tesla Cybertruck’s newest trim will undergo massive change in ten days, Musk says
Tesla is set to hike the price on March 1, so tomorrow will be the final day to grab the new Cybertruck trim for just $59,990.
It features:
- Dual Motor AWD w/ est. 325 mi of range
- Powered tonneau cover
- Bed outlets (2x 120V + 1x 240V) & Powershare capability
- Coil springs w/ adaptive damping
- Heated first-row seats w/ textile material that is easy to clean
- Steer-by-wire & Four Wheel Steering
- 6’ x 4’ composite bed
- Towing capacity of up to 7,500 lbs
- Powered frunk
Interestingly, the price offering is fairly close to what Tesla unveiled back in late 2019.

Elon Musk outlines plan for first Starship tower catch attempt
Musk confirmed that Starship V3 Ship 1 (SN1) is headed for ground tests and expressed strong confidence in the updated vehicle design.
Elon Musk has clarified when SpaceX will first attempt to catch Starship’s upper stage with its launch tower. The CEO’s update provides the clearest teaser yet for the spacecraft’s recovery roadmap.
Musk shared the details in recent posts on X. In his initial post, Musk confirmed that Starship V3 Ship 1 (SN1) is headed for ground tests and expressed strong confidence in the updated vehicle design.
“Starship V3 SN1 headed for ground tests. I am highly confident that the V3 design will achieve full reusability,” Musk wrote.
In a follow-up post, Musk addressed when SpaceX would attempt to catch the upper stage using the launch tower’s robotic arms.
“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk clarified.
His remarks suggest that SpaceX is deliberately reducing risk before attempting a tower catch of Starship’s upper stage. Such a milestone would mark a major step towards the full reuse of the Starship system.
SpaceX is currently targeting the first Starship V3 flight of 2026 this coming March. The spacecraft’s V3 iteration is widely viewed as a key milestone in SpaceX’s long-term strategy to make Starship fully reusable.
Starship V3 features a number of key upgrades over its previous iterations. The vehicle is equipped with SpaceX’s Raptor V3 engines, which are designed to deliver significantly higher thrust than earlier versions while reducing cost and weight.
The V3 design is also expected to be optimized for manufacturability, a critical step if SpaceX intends to scale the spacecraft’s production toward frequent launches for Starlink, lunar missions, and eventually Mars.
