Inside Rivian’s California battery lab: 180 kWh ‘megapacks’, carbon fiber, and ballistic shields
I found myself perplexed when I heard about Rivian’s plan to unveil an all-electric pickup truck with a battery pack nearly double the size of any other electric vehicle. Packing 80% more energy than Tesla’s flagship Model S and Model X, Rivian’s 180 kWh battery pack enables their full-size, adventure vehicles to travel 400+ miles (643 km) on a single charge. Rivian’s response? We actually call it the “megapack.”
At a flashy unveiling event in Los Angeles, the Michigan-based electric car company exited stealth mode and debuted their first two production vehicles: an all-electric pickup truck dubbed the R1T and an R1S luxury SUV. Capable of towing 11,000 lbs from its all-electric powertrain, the R1T is set to disrupt a $95-billion-dollar US truck market that’s largely dominated by Ford and GM. Rivian’s seven-seater, R1S SUV takes aim directly at gas guzzlers that are competing in the premium sports utility segment like Land Rover and Porsche’s Cayenne.
Powering the R1T Truck and R1S SUV is a quad-motor electric drivetrain that’s paired with one of Rivian’s three battery pack configurations, in 105 kWh, 135 kWh, and 180 kWh (the “megapack”). Rivian’s 180 kWh megapack holds enough energy to power a typical US household for more than two weeks. To learn more about the engineering that goes into each of Rivian’s battery packs, and the company’s plan to bring their ultra-long-range battery packs to market, I visited their research and development facility in Southern California.
The Battery Lab
Rivian’s battery lab is located in an unassuming industrial business park in Irvine, California. Still working its way out of nine-years in stealth mode, the 19,000 sq ft facility lacks any signage on its doors, yet has played a major role since mid-2017 when the company moved in to begin its research and development.
Upon entering the battery lab, I was greeted by the faint hum of testing equipment around me. Bright white lights illuminate a team of engineers in blue Rivian lab coats. I was told that the lab is where Rivian performs tests on the lithium-ion battery cells being used in its vehicles. The lab is also where battery module production is currently taking place, albeit mostly for prototype battery packs.
Leading Rivian’s battery and powertrain development is former hypercar engineer Richard Farquhar, who enjoys an insanely fun-sounding title: VP of Propulsion. Farquhar is one of the many members to recently join Rivian from renowned supercar brand McLaren. Rivian has brought on seven executives from the British company since late 2017, including Executive Director of Engineering and Programs, Mark Vinnels.

Rivian’s Battery Cells and Supplier
As Farquhar and I walk past a long row of glass cabinets, seen packed with hundreds of cylindrical battery cells in their testing phase, his eyes lit up with excitement while discussing the most intricate elements of the lithium-ion cells. “We want to understand the battery cells even better than their manufacturer,” Farquhar tells me.
It was the perfect segue I was looking for. “So, where is Rivian getting these battery cells from?” I ask. Farquhar wasn’t able to share the name of their battery partner but emphasized that Rivian wasn’t worried about their supply of cells. “I have no concern whatsoever,” Farquhar emphatically stated.
While Rivian isn’t ready to announce a battery supplier (yet), U.S. customs import records suggest that the company could be partnering with LG Chem to procure their cylindrical 2170 form factor lithium-ion cells. Rivian imported nearly 12,933 kg (28,500 lbs) of the 2170 cells from LG Chem in 2018 thus far — enough to support a test production run of ~195 Rivian battery modules at 15 kWh each.
Designed for extreme conditions
Inside the cabinets were cells being cycled through various charge and discharge states, and at various temperatures. Rivian wants to be the leading experts on battery technology, and in lieu of having numerous vehicles on the road, the company is testing its batteries using real-world simulations.
In the office area next to the lab, engineers analyze the testing data in real-time while adjusting computer-generated models. These tests aren’t just being done for a few hours or days, Farquhar tells me. One battery test has been ongoing for 11 months and counting. Rivian plans to analyze battery cell behavior over time and collect as much data as possible before making adjustments to it and entering production.
While standing the test of time is incredibly important for all battery cells, standing up to extreme conditions is just as critical. On one side of the lab, special climate-controlled containers simulate extreme temperature scenarios and test how the cells, modules, and full-sized battery packs react to these conditions. Rivian expects their adventure-ready vehicles to be capable of handling extreme temperatures and climates. Pushing their batteries to the limit isn’t just a precaution, but a necessity.
From Battery Cells to Modules
Farquhar tells me that Rivian engineers have worked on battery algorithms that leverage a driver’s profile, including their location and navigation data, and real-time weather conditions, to preemptively optimize a battery. For example, when a vehicle is on its way to a DC-charging station, the battery modules will be cooled ahead of time and prepared to accept the fastest charging rate. In essence, Rivian’s battery algorithms are adjusting battery cell settings, constantly, on the fly. By using machine-learning to build predictive models of various conditions, Rivian is able to tune battery cells, with high confidence, on conditions it may encounter.
Rivian’s R1T pickup truck and R1S adventure SUV will use the exact same battery modules. Battery capacity will vary based on the number of modules inside a skateboard-style battery pack design. Each Rivian module holds 864 cells, with 432 on the bottom and the other half stacked on top. In between the cells is a thin 7mm aluminum plate with liquid coolant. The unique structure isn’t known to be used by any other manufacturer.

A battery’s cooling system is one of the most important components within an electric car. If the batteries get too hot from fast charging or extended periods of high output, they could degrade in energy capacity and face permanent damage. If the batteries get too cold, they lose range. Keeping the batteries at their optimum temperature is a constant battle and is what truly differentiates any electric vehicle manufacturer.
Rivian’s solution to battery thermal management is the use of a cold plate that’s placed between two battery cells. A single cooling system chills both layers of cells at the same time. According to Rivian, this reduces the amount of energy needed to power the system, thereby allowing the car to have better range in all types of conditions. In addition to saving power, the cooling system’s design allows for tighter packaging of cells within the modules. According to Farquhar, Rivian’s unique packaging allows the module to be 25% denser than any other battery module on the market.
Rivian’s Battery Pack: Carbon Fiber and Ballistic Shields
I saw it from afar. Carbon fiber. Walking toward a station that was outfitted with Rivian’s line of 135 kWh and 180 kWh battery packs, my eyes were immediately drawn to a fibrous-looking cover plate.
Securing Rivian’s battery modules and high-voltage cabling in place is a carbon-fiber composite shell. Engineers were able to create a unique, high-strength geometric shape out of the carbon fiber while keeping weight to a minimum. Rivian seals the battery pack to be completely watertight. The pack is bolted into the frame of the vehicle and then covered by a smooth ‘ballistic shield’, which prevents damage to the underside of the battery pack and protects occupants within the vehicle’s cabin. The ballistic shield is fitted to the entire underbody of the vehicle.
Having a watertight battery pack that’s armored by a ballistic shield bodes well for a company whose mission is to build extreme off-road vehicles. That’s the messaging Rivian wants consumers to see. The vehicles are designed to be adventure-ready, being able to wade through 1 meter of water, climb 45-degree inclines, and drive over boulders.
Rivian’s Executive Director of Engineering and Programs, Mark Vinnels, told Teslarati that they dropped the vehicle on a boulder from 2 ft in the air, just to be able to verify the battery pack’s integrity in extreme off-road situations.
What about Production?
With the design of its battery module completed, a significant portion of the team’s focus has turned to module production — specifically, designing methods to quickly and efficiently manufacture modules by using automation. Rivian has set up a pilot production line at the Irvine facility, ahead of its anticipated summer 2020 production.
Rivian is actively developing automation processes for the entire battery module assembly. In a corner of the battery facility were two Japan-made robots that were brought in from the company’s massive factory in Normal, Illinois. A robotics technician was actively working on the robots, while I watched a module come together on the line.
The entirety of Rivian’s module and battery pack production is slated to be installed in a 300,000 sq-ft section of Rivian’s 2.6M sq ft factory in Normal, IL. The plant was acquired by Rivian in 2017 for $16M and originally part of an expansion made by Mitsubishi that the Japanese automaker never occupied. Farquhar stated that the area is virtually a “clean slate.”

Rivian expects to start deliveries of the R1S and R1T in the second half of 2020, with the largest battery packs entering production first. The R1S SUV starts at $72,500 (before tax credits) and has a range that varies between 240 to 410+ miles (385 to 660 km). Rivian’s R1T pickup truck has a starting price of $69,000 and similar range as the R1S at 230 to 400+ miles (370 to 643 km), depending on battery pack size. Both vehicles will support CCS DC-fast charging up to 160 kW and are capable of accelerating from 0-60 mph in 3 seconds.
Rivian is accepting preorders at its website.
Tesla just raised Model Y prices for the first time in two years, with the largest increase being $1,000.
The move signals shifting dynamics in the competitive electric vehicle market as the company continues to work on balancing demand, profitability, and accessibility.
The new pricing affects premium trims while leaving entry-level options unchanged. The Model Y Premium Rear-Wheel Drive (RWD) now starts at $45,990, a $1,000 increase.
The Model Y Premium All-Wheel Drive (AWD)—previously referred to in the post as simply “Model Y AWD”—rises to $49,990, also up $1,000. The top-tier Model Y Performance sees a more modest $500 bump, bringing its starting price to $57,990.
Tesla Model Y prices just went up:
New prices:
🚗 Model Y Premium RWD: $45,990 – up $1,000
🚗 Model Y AWD: $49,990 – up $1,000
🚗 Model Y Performance: $57,990 – up $500 https://t.co/e4GhQ0tj4H pic.twitter.com/TCWqr3oqiV— TESLARATI (@Teslarati) May 16, 2026
Base models remain untouched to preserve affordability. The entry-level Model Y RWD holds steady at $39,990, and the base Model Y AWD stays at $41,990. This selective approach keeps the crossover accessible for budget-conscious buyers while extracting more revenue from higher-margin configurations.
After years of aggressive price cuts to stimulate volume amid slowing EV adoption and rising competition from rivals like BYD, Ford, and GM, Tesla appears confident in underlying demand. Recent lineup refreshes for the 2026 Model Y, including refreshed styling and efficiency gains, have helped maintain its status as America’s best-selling EV.
By protecting base prices, Tesla avoids alienating price-sensitive customers while improving margins on the more popular variants.
Tesla Model Y ownership review after six months: What I love and what I don’t
For consumers, the changes are relatively modest—under 3% on affected trims—and still position the Model Y competitively against gas-powered SUVs in the same class. Federal tax credits and potential state incentives may further offset costs for eligible buyers.
This marks a subtle but notable shift from the deep discounting era that defined much of 2024 and 2025. As the EV market matures into 2026, Tesla’s pricing strategy will be closely watched for clues about production ramps, new variants like the rumored longer-wheelbase Model Y, and broader profitability goals.
In short, today’s adjustment reflects a company that remains dominant yet pragmatic—willing to test higher pricing where demand supports it. It is unlikely to deter consumers from choosing other options.
Elon Musk cannot be fired from SpaceX, and there’s a reason for that.
In a blunt post on X on Friday, Elon Musk confirmed plans to structurally shield his leadership at SpaceX, ensuring he cannot be fired while tying a potential trillion-dollar compensation package to the company’s long-term goal of establishing a self-sustaining colony on Mars.
Yes, I need to make sure SpaceX stays focused on making life multiplanetary and extending consciousness to the stars, not pandering to someone’s bullshit quarterly earnings bonus!
Obviously, IF SpaceX succeeds in this absurdly difficult goal, it will be worth many orders of…
— Elon Musk (@elonmusk) May 15, 2026
The revelation stems from a Financial Times report detailing SpaceX’s intention to restructure its governance and compensation framework. The moves are designed to protect Musk’s control and align his incentives with the company’s founding mission rather than short-term financial pressures. Musk’s reply left no ambiguity:
“Yes, I need to make sure SpaceX stays focused on making life multiplanetary and extending consciousness to the stars, not pandering to someone’s bullshit quarterly earnings bonus!”
He added that success in this “absurdly difficult goal” would generate value “many orders of magnitude more than the economy of Earth,” though he cautioned that the journey will not be smooth. “Don’t expect entirely smooth sailing along the way,” Musk wrote.
The strategy reflects Musk’s deep concerns about how public-market expectations could derail SpaceX’s core objective. Founded in 2002, SpaceX has repeatedly stated its purpose is to reduce the cost of space travel and ultimately make humanity a multiplanetary species.
Unlike Tesla, which went public in 2010 and has faced repeated battles over Musk’s compensation and board influence, SpaceX remains privately held. Musk has long resisted taking the rocket company public precisely to avoid the quarterly earnings treadmill that forces most CEOs to prioritize short-term stock performance over ambitious, high-risk projects.
By embedding protections against his removal and linking any outsized pay package to verifiable milestones—such as a functioning Mars colony—SpaceX aims to insulate its leadership from activist investors or board members who might demand faster profits or safer bets.
Musk has referenced past experiences, including his ouster from OpenAI and shareholder lawsuits at Tesla, as cautionary tales. In those cases, he argued, external pressures risked diluting the original vision.
Critics may view the arrangement as excessive, especially given Musk’s already substantial voting power and wealth. Supporters, however, argue it is a necessary safeguard for a company pursuing goals measured in decades rather than quarters. Achieving a Mars colony would require sustained investment in Starship development, orbital refueling, life-support systems, and in-situ resource utilization—technologies that may deliver no immediate financial return.
Musk’s post underscores a broader philosophical point: true breakthrough innovation often demands tolerance for volatility and a willingness to ignore conventional business wisdom. As SpaceX prepares for increasingly ambitious Starship test flights and eventual crewed missions, the new governance structure signals that the company’s North Star remains unchanged—humanity’s expansion beyond Earth.
Whether the trillion-dollar package materializes depends on execution, but Musk’s message is clear: SpaceX exists to reach the stars, not to chase the next earnings beat. For investors or employees who share that vision, the protections are not a perk—they are a prerequisite for success.

Tesla discloses two Robotaxi crashes to NHTSA
Newly unredacted data filed with the National Highway Traffic Safety Administration (NHTSA) reveals the two incidents.
Tesla has disclosed information on two low-speed crashes that occurred in Austin with its Robotaxi platform. These incidents occurred with teleoperators steering the vehicle, and there were no passengers in the car at the time they happened.
Newly unredacted data filed with the National Highway Traffic Safety Administration (NHTSA) reveals the two incidents.
The first crash took place in July 2025, shortly after Tesla launched its nascent Robotaxi network in Austin. The ADS reportedly struggled to move forward while stopped on a street. A teleoperator assumed control, gradually accelerating and turning left toward the roadside. The vehicle then mounted the curb and struck a metal fence.
In the second incident, in January 2026, the ADS was traveling straight when the safety monitor requested navigation support. The teleoperator took over from a stop, continued forward, and collided with a temporary construction barricade at approximately 9 mph, scraping the front-left fender and tire.
Tesla Robotaxi service in Austin achieves monumental new accomplishment
Tesla has previously told lawmakers that teleoperators are authorized to pilot vehicles remotely—but only at speeds below 10 mph, as the only maneuvers they were approved to perform were repositioning in awkward areas.
“This capability enables Tesla to promptly move a vehicle that may be in a compromising position, thereby mitigating the need to wait for a first responder or Tesla field representative to manually recover the vehicle,” the company stated in filings earlier this year.
Before this week, Tesla redacted the NHTSA reports, but they decided to reveal all 17 Robotaxi incidents recorded since the launch in Austin last Summer. Most of the other crashes involved the Tesla being struck by other road users and were not caused by the self-driving suite itself.
There were other incidents, including two additional self-caused accidents involving the ADS clipping side mirrors on parked cars. In September 2025, one Robotaxi struck a dog that darted into the roadway (the dog escaped unharmed), while another made an unprotected left turn into a parking lot and hit a metal chain.
Although Waymo and Zoox have reported more total crashes, Tesla operates at a far smaller scale. The cautious pace reflects the company’s broader safety concerns; it has been very slow with the Robotaxi rollout to ensure the suite is ready for operation.
Last month, CEO Elon Musk acknowledged that “making sure things are completely safe” remains the primary bottleneck to expanding the network, describing the company’s approach as “very cautious.”
The unredacted filings arrive amid heightened regulatory scrutiny of autonomous vehicles. NHTSA recently closed a separate probe into Tesla’s Full Self-Driving software repeatedly striking parking-lot obstacles such as bollards and chains—a problem that also prompted a recall at Waymo last year.
Tesla Robotaxi has been a widely successful program in its early days of operation, and the transparency Tesla brings here is greatly appreciated. Incidents will happen, of course, but the honesty gives customers and regulators a sense of where Tesla is in terms of developing its self-driving and fully autonomous ride-hailing suite.
