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 Cybertruck’s three configurations are all the same on the outside from an appearance perspective, but they differ slightly in price, range, performance, and other features. After yesterday’s price adjustment, Tesla’s Base All-Wheel-Drive Cybertruck is now priced at $74,990, a far cry from the $59,990 it started at several months ago.
At $60,000, the Cybertruck All-Wheel-Drive is a steal: no pickup, electric or gas-powered, comes close in terms of overall driving capability thanks to Steer-by-Wire; no truck is more fun to drive at that price, and add in Full Self-Driving for $99 per month, and you truly have the best possible pickup on the market, at least if you’re planning to use it for driving.
I unfortunately didn’t have the equipment to test towing and payload and how it impacts the truck.
But at $75,000, is it still worth it? Obviously, the question gets to be more difficult because of the $15,000 difference. But there’s still an argument.
I spent the last week with this awesome truck, and when I took it back, I was sad because it truly is the best Tesla in the lineup. I formerly said the Model S was my favorite Tesla, but after a week with Cybertruck, I can easily say it would be my choice over the now-defunct all-electric sedan.
What makes it so great? Well, a lot of things, and there are some things that I’d like to see change. However, this is a truck that truly has a serious argument for those who are thinking of trying something completely different.
Exterior and Interior
This build comes with 18″ Molten Wheels as the standard offering, but 20″ Core Wheels with 35″ tires are also available. The standard wheel option on this affordable model is not my favorite, but it can be easily swapped for something more attractive.
Overall, this particular build did have some panel gap issues that were especially noticeable between the hood and both front quarter panels. This is obviously not an “across the board” issue, as the Cyberbeast I took home for comparative reasons was significantly better overall.

The interior is different, with its textile material instead of the vegan leather. Personally, I missed the leather due to the ventilated seats, but I prefer the textile as I personally felt like they were more comfortable. This is something I’d definitely consider if I were between the three trim levels and money was not really an issue.
After 610 miles on Monday in this thing, I did not feel any different than I did when I left my house that morning. It feels like a living room on wheels; after a long drive, you truly do not feel as if you’ve been in a car all day long.
My biggest interior complaints were that I’d like at least two USB-C ports in the front; you are confined to just one, and it’s hidden in the center console. The rear row has two ports. Additionally, the windshield is super difficult to clean, so if you end up buying one of these, save your back and get something that extends.
Driving Performance and Comfort
One of the most surprising things about Cybertruck is the fact that it is perhaps the smoothest ride of any Tesla available. Most believe it might be rough, stiff, and rugged like most trucks, maybe not as forgiving on the back and bottom as you sit in it for an extended period of time.
I’m here to tell you, you won’t regret sitting in a Cybertruck for a long drive.
I put as many people who dislike EVs, don’t like Cybertrucks, or use trucks for work, and judge the Cybertruck in this thing in the past week. Every single person who got in this truck loved it: they loved the speed, the handling, FSD, the space, the capability, and the feel.
As previously noted, even after hundreds of miles and 14 hours spent driving around Pennsylvania, I didn’t feel tired, exhausted, or in any hurry to come home. I would have driven another 300 miles without question.
Final Thoughts
If I had my choice of the three Cybertruck trims, I think I’d take the All-Wheel-Drive for a few reasons. Initially, the price is more attractive, it is not that stripped of features, and it has everything I need.
Is it worth it at $75,000? I believe it is. I’ve driven trucks that are at a higher price point and consider this to be a better product from a driving and experience perspective. However, other pickups on the market have more towing capacity, payload capacity, and range. They do not have FSD or steer-by-wire, the two things that truly make the Cybertruck in a league of its own.
I can’t think of a time in recent memory that I’ve been this excited to drive a vehicle each day, and I literally look for excuses to drive my Model Y on a daily basis. This Cybertruck just blows the Model Y out of the water in every possible way, at least in my opinion. With the size, performance, and driving experience, there is no better Tesla out there.

County vote hands Elon Musk’s Vegas tunnel network a huge new target
Clark County approved 19 more Vegas Loop stations, pushing Boring Company’s entitled total to 123.
The Boring Company just got permission to nearly double how far Vegas Loop can reach. Clark County commissioners approved 19 additional stations for the underground transit system, bringing the total entitled to 123, the company said in a post on X thanking the county for the vote. Elon Musk’s tunneling company also flagged the direction it sees the project heading long term. “Because Loop is point-to-point with no intermediate stops, in the limit, one could have a Loop station in every driveway,” the company wrote.
That framing captures how far the ambitions have moved. The Vegas Loop opened its first stretch of tunnel in 2021 and has grown its footprint through a string of county approvals since. In 2023, commissioners signed off on 18 additional stations, part of a plan that later doubled the system’s target to 69 stations across 65 miles. By the end of that year the company was describing a build out closer to 93 planned stations. Last year the long term design called for 104 stations across 68 miles of tunnel. The new approval pushes that number to 123, another jump in a project that keeps outgrowing its own blueprints.
The Boring Company gets approval for more stations in Las Vegas
Station count on paper is still well ahead of what riders can actually use. As Teslarati reported earlier this month, the network has about 11 open stations and has carried more than 4 million passengers since it began running, with newer stops at Fontainebleau and Sahara among the latest additions to the Strip corridor. A tunnel connection to Harry Reid International Airport remains under construction and has already slipped past its original first quarter target. The company is also racing to finish a Westgate to Paradise Road segment that Las Vegas Convention and Visitors Authority CEO Steve Hill has said it hopes to have running in time for November’s Formula 1 race.
The gap between entitled stations and operating ones is where the real story sits. Regulatory approval gives Boring Company the legal runway to keep tunneling toward new resorts, residential pockets and eventually the airport, but building each connection still comes down to boring machines, fire safety sign offs and construction timelines that have slipped before. The company’s Prufrock series machines set an internal record in March with a 2.28 mile tunnel near Westgate, evidence that construction has been picking up even as the list of approved destinations grows faster than the tunnels themselves.
Musk’s driveway comment reads as aspirational rather than a near term plan, but it fits how Boring Company has talked about Vegas Loop from the start: treat every approval as a floor, not a ceiling, and keep pushing county officials for room to dig.
SpaceX announced today that it would expand its launch capabilities into a new U.S. state: Louisiana.
Today, SpaceX, in conjunction with the Louisiana Economic Development Office, said that it will establish a new launch facility, which it will call Starbase, Louisiana. It will be located near Vermilion Parish, supporting thousands of launches each year, at least eventually.
CEO Elon Musk commented by stating, “Starbase Louisiana will ultimately have over a dozen launch towers, enabling more than 30 Starship flights per day and making it the biggest launch site on Earth!”

SpaceX makes sci-fi real. https://t.co/C7Ht0U12ba
— Elon Musk (@elonmusk) August 25, 2026
The expansion is SpaceX’s latest move to push its launch cadence to be more frequent than ever. SpaceX said that Starbase, Louisiana, will be built to “support thousands of Starship flights a year,” with the first coming in 2029.
SpaceX announced the new facility in partnership with the Louisiana Economic Development Office as it will bring a major influx of jobs and investments into the area. Currently, it will produce more than 3,000 new jobs in Louisiana, and SpaceX plans to invest at least $100 billion into the entire facility, ensuring that many jobs are created as a result.
Environmental Responsibility
SpaceX acknowledges the impact launches could have on marshlands, local wildlife, and water sources. Here’s how the company plans to help with the issues in Vermilion Parish:
- Restoring the Shoreline: “In Vermilion Parish, the shoreline is eroding between 3.3 and 23 feet per year. We’re partnering with state and federal agencies to expand Louisiana’s Coastal Master Plan and Coastal Wetlands Planning, Protection and Restoration Act projects, including Gulf shoreline protection breakwaters designed to reduce wave energy and slow loss along the Gulf edge.”
- Rebuilding the Marshlands: “In working with the state, we’re planning thousands of acres of marsh creation using beneficial-use placement of dredged material and offshore sediment sources. Restoration will also include interior marsh bank stabilization and rebuilding marsh in remnant canals. These projects can reconnect fragmented wetlands, restore natural buffers against storms, and return habitat that has been lost to erosion and historic canalization.”
- Preserving Coastal Wildlife: “Pecan Island and nearby wetlands are high-value habitat for migratory waterfowl, shorebirds, wading birds, and other coastal wildlife. SpaceX is not developing the full footprint of the land and will preserve wetlands and wildlife habitat. At existing launch sites, waterfowl and other birds continue to use nearby habitat during operations. Working with wildlife agencies, landowners, and conservation groups, SpaceX will support monitoring and management so this habitat stays productive and hunting, fishing, birding, and other recreational activities that are part of this coast’s culture can continue.”
SpaceX shares rose about 2.5 percent on the news.
