Rivian transitioned to their second-generation vehicles in 2025. One of the goals with their second-gen vehicles was to reduce vehicle costs, so one of the changes was to reduce battery options for these new models.
Rivian slimmed down its battery pack choices by reducing them from four options to three. Instead of offering Standard, Standard+, Large, and Max battery sizes, they now only offer Standard, Large, and Max batteries packs.
However, to reduce complexity further, initial production runs only had two battery sizes — Standard and Max. For customers who ordered a Rivian with a large battery pack, Rivian actually included a Max battery pack software limited to the range of a Large battery. These vehicles were coined as Large+ (Plus) batteries by the community, and Rivian soon adopted the name.
Advantages of a Large+ Battery
For customers who have a software-locked Max battery, there are several perks. Normally, with a lithium nickel manganese cobalt (NMC) battery, you’d want to avoid charging the vehicle to 100% on a daily basis to prevent premature aging. However, with a software-locked Max battery, customers can actually charge to 100% since the vehicle will stop charging once it hits 100% of the “large” battery.
A Max battery pack can store 140 kWh while a Large is 108.5 kWh, so charging to 100% on a Large+ battery is equivalent to charging to just 78% on a Max battery pack. This lets customers continuously take advantage of their vehicle’s full range without any ill effects on battery degradation — a really nice perk.
However, there’s more. According to Wassym Bensaid, Rivian’s Chief Software Officer, Rivian will soon offer customers the ability to unlock the full benefit of the Max battery pack, essentially purchasing the Max battery after the fact.
This is a really nice option, as some customers may discover they could use the extra range, especially as their battery degrades slowly over the years. It’s not a must-have, but having the option is a great addition.
How to Tell If You Have a Large+ Battery
If you’re not sure if your vehicle has a Large+ battery, you can tell by going to your vehicle settings. Your vehicle should have about 300 miles of range. If it has about 250 miles or 400 miles fully charged, then you have a Standard or Max battery pack.
To check if you have a Large or Large+ battery pack, you’ll need to be in your vehicle and navigate to Settings (gear icon), then tap on the About menu item on the left. You’ll see a rendered model of your vehicle and directly underneath, you’ll see your model, which includes the battery pack size. You should see either Large or Large Plus in the model description.
What You Get By Unlocking
We previously dived deep into Rivian’s battery options for both its Gen 1 and Gen 2 R1 series vehicles, but in short, you can expect your Rivian’s range to increase to the same level as a vehicle with a Max battery pack when unlocking the full capacity of the Max battery.
This will take your Rivian R1S or R1T from about 330 miles of range (531 km) to about 420 miles (676 km), depending on the model.

Price to Unlock Max Battery
While Rivian hasn’t announced the price to unlock the Large+ battery’s full potential, expect it to cost about $6,000. This is the same price as purchasing the Max battery pack at the time of configuring your vehicle, so don’t expect a discount, at least initially.
It’s possible as these vehicles get older, Rivian realizes that people may not want to buy a $6,000 add-on for a 5 or 10-year-old vehicle, and at that point, they may consider lowering the price.
Performance Upgrade: Rivian recently announced the ability to purchase the Performance option for dual motor vehicles as well, so owners of Large+ battery packs can double dip and get the Max battery pack and unlock the Performance version of their vehicle as well. Rivian priced the Performance software upgrade at $5,000, which is also the same price as getting it from the factory.
How to Unlock Large+
While the ability to unlock your Large+ battery pack isn’t available yet, expect the upgrade option to be available in the Rivian app and in the vehicle — similar to the Performance upgrade.
Release Date
Wassym didn’t say when the software battery unlock would arrive, but it seems that it will be coming as part of a future OTA update, which will bring the purchase option to your Rivian. Just like with the Dual Performance upgrade, you’ll be able to use Rivian Reward credits towards the unlock as well.

For years, Rivian owners have had to play detective to figure out exactly how much life is left in their battery packs. Whether it’s comparing current maximum range to original "as-new" figures or diving into third-party API tools to see the estimated usable kWh, getting a straight answer has been a bit of a chore. However, that is finally about to change.
According to EPA certification documentation for the R2 that surfaced online earlier this week, Rivian is officially working on a dedicated battery health menu. This new feature will be delivered to vehicles via a future over-the-air (OTA) software update, bringing a level of transparency to the "About" screen that owners have been requesting for a long time.
What’s Coming to the Battery Menu
The leaked documentation reveals that the new menu will provide several key data points that were previously hidden from the user interface. Owners will soon be able to see:
Battery state of health: A clear percentage representing the pack’s current capacity relative to when it was new.
Distance since last updated: A timestamp of sorts showing when the health metric was last calculated.
Max potential charge rate: The peak speed at which your specific pack can currently accept power.
Current charge rate: Real-time data on how fast the vehicle is charging at that moment.
Currently, owners who want this level of detail often have to navigate into Rivian’s hidden RiDE (service) mode and do some quick math or rely on third-party telemetry services. Being able to pull up an exact number for battery state of health without doing some mental gymnastics or needing a service visit is a massive win for long-term ownership confidence.
Timing and the R2 Connection
While the R2 EPA certificate confirmed the feature's existence, there is no official word yet on exactly when it will roll out to the fleet. The Rivian lineup is currently overdue for a major software update, and we expect one to start rolling out publicly in the coming weeks.
It is possible that this menu will debut alongside the first R2 Performance deliveries later this spring. Since the R2 is built on a new architecture with a native heat pump and updated battery specs, launching a more detailed health menu at the same time makes a lot of sense for the brand's next-gen push.
Providing this level of transparency is a smart move by Rivian. As these vehicles age and enter the used market, having a "certified" battery health percentage visible in the settings will be a crucial tool for both current owners and future buyers. It’s exactly the kind of "pro-consumer" software move that separates modern EV makers from traditional legacy brands.
Rivian has built a reputation on outfitting its vehicles with unique capabilities designed specifically for off-road environments. While its engineers previously experimented with a Tank Turn feature that allowed the R1T to spin completely in place, that feature was ultimately scrapped due to the severe environmental damage it caused to trails.
However, a newly published patent titled "Systems and Methods for Providing a Vehicle with a Torque Vectored K-Turn Mode" (US12576849 B2) reveals that Rivian’s engineers have developed a new, more refined solution for navigating impossibly tight corners.
The Evolution of the Turn
The core concept behind this new patent is to use Rivian’s independent motor architecture to control how the vehicle rotates about its own chassis. When a standard vehicle turns, the turning radius is limited by how far the front wheels can physically pivot. The newly patented Kick-Turn Mode bypasses this physical limitation by applying opposing forces to the front and rear axles.
Kick Turn helps your Quad pivot like it’s got dance moves. That's the magic of four motors with fully independent torque vectoring.
According to the patent, the vehicle’s control circuitry constantly monitors the steering wheel input. When a driver turns the steering wheel past a specified threshold (for example, past 70 percent of its maximum rotation or after completing 2.5 full revolutions), the system automatically engages the Kick-Turn Mode.
Once engaged, the vehicle fundamentally changes how it distributes power. When the driver presses the accelerator, the system provides forward torque to the turned front wheels while simultaneously applying backward torque to the rear wheels.
This opposing torque distribution creates a unique physical dynamic. The forward torque causes the turned front wheels to intentionally slip laterally across the ground, pulling the front of the vehicle through the turn.
Meanwhile, the backward torque applied to the rear wheels keeps them in substantial static contact with the ground. By anchoring the rear wheels and sliding the front wheels, the vehicle effectively pivots around a point located directly underneath the rear chassis, resulting in a dramatically tighter turning radius than a conventional steering maneuver could ever achieve.
The Front Dig Mode Alternative
The patent also details a secondary, less aggressive turning feature called "Front Dig Mode". This mode is engaged when the steering wheel is turned past a "lower turn threshold" (for example, 1.5 revolutions) but hasn't yet reached the full Kick-Turn threshold.
Rivian Wave
In Front Dig Mode, the system provides forward torque to the turned front wheels and forward torque to the outer rear wheel. However, the system actively applies resistance, either by applying the physical brake or inducing backward torque, to the inner rear wheel. This essentially drags the inner rear wheel, acting as a pivot anchor that tightens the turn radius, though not quite to the extreme degree of the full Kick-Turn Mode.
Intelligent Safeguards
Rivian's patent notes that these torque-vectored turns require precise control. The vehicle's control circuitry constantly monitors wheel slip, vehicle rotation rate, and throttle input. If the system detects that the vehicle is rotating too fast, or if a rear wheel begins to slip during a Kick-Turn, the computer will instantly adjust the torque output or apply the brakes to correct the maneuver and ensure the vehicle remains stable.
The system can even detect if the vehicle is on an incline or a banked surface and automatically adjust the torque distribution to compensate for gravity. Rivian’s Kick-Turn feature is currently available on 2nd-Generation Quad-Motor R1S and R1T variants. It is not available for Gen 1 Quad-Motor vehicles due to changes in the ECU and drivetrain architectures.
