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 is ending Cybertruck production sometime in mid-2027, according to CEO Elon Musk.
Musk made the announcement on X last night, which came as a shock to many. He said that the Cybertruck will end production “to make room for increased Cybercab production” at Gigafactory Texas.
It is a huge blow to the fans of Tesla who have come to love the Cybertruck and identify with it as a symbol of their fandom. It has been the best-selling electric pickup, but it has had an underwhelming sales performance in terms of what was expected. This is mostly due to Tesla not meeting the prices it planned to offer the Cybertruck, as its unveiling and actual release were four years apart.
Tesla will be winding down production of the Cybertruck at Gigafactory Texas around the middle of next year to make room for increased Cybercab production
— Elon Musk (@elonmusk) November 6, 2026
Overall, the responses were mixed. Some fans understood the move toward Cybercab production, especially as Tesla is truly pushing the autonomous future through its Robotaxi platform. However, others did not understand it.
“Damn, how many Cybercabs do you guys need?” one response read. Another said it was “Sad but understandable.”Even analyst Gary Black had responded to the news, stating he hoped Tesla planned to replace it with a traditional pickup design.
It doesn’t seem like that will be the case.
Tesla is so hell-bent on delivering autonomy and eventually providing a driverless service that owning a car seems like an arbitrary idea, according to their thesis. Instead, Cybercabs will be available to pick you up and drop you off on demand, safely, without any human help.
As a result, Tesla has thinned its lineup considerably, and one can only ask where the vehicle lineup goes from here. Eventually, it seems like Cybercab could be the only vehicle that Tesla will sell.

SpaceX’s next Starship flight set to make history on Friday the 13th
SpaceX is targeting Friday, November 13 for Starship Flight 15 and its first ship catch.
SpaceX is targeting Friday, November 13 for Starship Flight 15, the mission the company plans to use for its first attempt at catching the ship itself with the launch tower.
SpaceX Vice President of Launch Kiko Dontchev shared the date on stage at the UP.Summit on Thursday, according to Ars Technica’s Eric Berger, who was in attendance. It is the first launch target to come directly from a SpaceX executive. Until now, the public schedule had relied on FAA air traffic planning slides, which listed Flight 15 for no earlier than November 8 and later November 12. SpaceX has not posted an official mission page yet, and no launch time has been shared.
The date lands inside the window Elon Musk sketched out last month. Speaking at Giga Texas on October 10, Musk said the flight would “probably launch a little bit before Thanksgiving,” as Teslarati reported. On SpaceX’s third quarter earnings call ten days later, he confirmed that Flight 15 would try to catch both the Super Heavy booster and the ship, and put the odds of a successful ship catch at “more likely than not.” SpaceX also aired an animation of the maneuver during that webcast, showing the ship swinging vertical over Starbase before dropping into the tower’s chopsticks.
The hardware is ready. Booster 22 fired all 33 of its Raptor engines for a full duration static fire at Pad 2 on October 25. Ship 42 followed with a single engine burn simulating a deorbit maneuver on October 26 and a 60 second firing of all six engines the next day, according to NASASpaceflight. Ship 42 had already rehearsed the catch in September, when the Pad 2 arms lifted it into position and crews connected the quick disconnect arm while the vehicle hung from the tower.
The remaining hurdle is regulatory. The FAA’s Starship page does not yet list a Flight 15 license. SpaceX President Gwynne Shotwell said in October that, after “significant constructive engagement with the FAA,” she expects the license to cover a return to the launch site and a tower catch for both stages. Bringing the ship home means a reentry path that heads toward land, rather than ending over open ocean as every Starship flight so far has.
SpaceX has caught Super Heavy three times, on Flights 5, 7 and 8, but the ship comes back from orbital velocity and has never been caught. Flight 14 on September 28 was the first Starship to reach orbit, deploying 26 Starlink V3 satellites before splashing down despite an early engine shutdown that Musk blamed on engine computer software.
Musk has called a successful ship catch “the first time that there’s been full recovery of an orbital class rocket,” and he has already named the step after it: a Flight 16 where both the booster and the ship fly again. NASASpaceflight reports that Ship 43, the next vehicle in line, is set for static fire testing in December.
EVgo has tapped Tesla Superchargers for its most recent efforts to expand its charging presence in the United States, a move that seems logical based on the effectiveness of the automaker’s own infrastructure.
EVgo opened its first Supercharger site in Illinois, a 12-stall station near downtown Chicago at 3145 South Ashland Avenue in the Riverside Square & River’s Edge center, right beside a grocery store. This marks the start of the company’s plan to deploy hundreds of Supercharger stalls across the United States, primarily at grocery-anchored Regency Centers properties where drivers can shop, eat, or run errands while they charge.
We’ve opened our first EVgo Supercharger location in Illinois, marking the start of our plan to add hundreds of Supercharger stalls across the U.S.
Designed for both NACS and CCS vehicles with Magic Dock technology, these new sites help make fast charging more accessible and convenient for all EV drivers. Learn more: https://t.co/V92t5FDryQ
— EVgo Fast Charging Network (@evgonetwork) November 5, 2026
The new location uses Tesla’s Magic Dock technology so both NACS and CCS vehicles can plug in natively without drivers needing to carry their own adapters. Peak power reaches 325 kW at this site, with pricing set between $0.25 and $0.35 per kWh depending on the hour—the same rate for Tesla and non-Tesla drivers.
The stalls also appear in Tesla’s in-car navigation and Trip Planner, making them easy for Tesla owners to find and route to. Illinois has seen EV registrations rise nearly 60 percent over the past two years, and EVgo’s broader network has experienced more than 700 percent growth in charging demand over three years, so the timing fits the market’s trajectory.
Choosing Tesla hardware through the Supercharger for Business program turns out to have been a smart, practical move.
Tesla’s V4 stalls and cabinets deliver high, reliable power with a proven track record of strong uptime, while Magic Dock delivers true dual-standard compatibility in one package. Because the sites show up in Tesla’s navigation tools, EVgo instantly gains visibility among millions of existing Tesla drivers, which should raise utilization and help the company double its addressable market as more vehicles adopt NACS. EVgo still owns the stations and sets pricing, yet benefits from Tesla’s established hardware, longer cables, and operational support.
The result is faster, lower-risk infrastructure expansion that serves every EV driver—Tesla or otherwise—with convenient, high-power charging at everyday retail locations. For drivers, that means fewer adapters, more predictable stops, and a denser network just as electric vehicles become everyday transportation.
