Rivian Large+ (Plus) Battery Pack Unlock Coming Soon

Rivian Wave

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.

Rivian Performance Upgrade: What It Adds and Price

Rivian Wave

When purchasing a new Dual Motor Rivian, you might have considered the Performance option, which was offered as a $5,000 upgrade at the time of ordering. However, Rivian is now offering the Performance upgrade as an in-app or in-car purchase for Dual Motor R1S and R1T owners.

The Performance upgrade boosts the vehicle’s horsepower and torque, while also introducing new driving modes.

Features

The Dual Motor Performance upgrade adds additional features to the R1S and R1T vehicles, with the most notable being a major performance boost.

This upgrade increases both horsepower and torque, reducing the 0 to 60 mph time from 4.5 seconds to an impressive 3.4 seconds.

In addition to the power boost, the upgrade introduces new driving modes: Sport, Soft Sand, and Rally. Each mode adds specialized capabilities—Sport for track performance, Rally for off-road adventures, and Soft Sand for tackling sandy terrains.

The Performance upgrade is available for Gen 1 and Gen 2 vehicles.

Launch Mode Reserved for Tri and Quad

Even if you’re familiar with the roller-coaster-like feeling of launching an EV, the performance upgrade is going to be a big step up, and it’ll be a useful upgrade for off-roading too. The noticeable increase in horsepower not only helps you launch with more power but also makes crawling over rocks or pushing through water more effortless.

However, for owners hoping to take their R1 series vehicles to the track, there’s something to keep in mind—this upgrade, just like buying a Dual Motor Performance model, doesn’t include Launch Mode. That feature is only reserved for the Tri and Quad configurations.

Price

If you’re craving a bit more power or want to relive the thrill of launching your Rivian for the first time, the Performance upgrade is likely a great choice. It adds over 120 horsepower, giving you about a 25% boost in performance.

The upgrade costs $5,000 USD / $7,000 CAD, whether purchased over-the-air or at the factory. If you own a Dual Motor Rivian, you can easily buy it through the app or the vehicle itself, available with software update 2024.06 or later.

How to Restart, Reboot, or Reset Your Rivian’s Frozen Screen

Rivian

If your Rivian is experiencing odd issues or the screen has become frozen or unresponsive, a reboot of the infotainment system may fix the issue.

There are several ways to reboot the computer that powers all of Rivian’s screen, including the rear display for passengers in the back. It doesn’t matter which Rivian you have, as these reboots are applicable to both Gen 1 and Gen 2 vehicles.

Fix Frozen Display - Infotainment Reboot

Rebooting the infotainment unit is the simplest reboot and should be your first choice when you encounter an issue with your Rivian. Infotainment reboots, also known as the “two-finger salute,” involve holding the far left and far right buttons on the steering wheel down. These are the outermost buttons located next to the scroll wheels on the steering wheel. Press them and down them down for 15 seconds to reboot the computer.

The vehicle will beep, and a graphic will be displayed on the driver’s display. Continue holding the buttons down until the screens flash to black. Once the screen goes dark, you can let go of the buttons and the infotainment unit will reboot. The whole process takes about 30-45 seconds, and you’ll soon see the displays come back on with the Rivian logo.

While this reboot can also be done while driving, we don’t recommend it, as you’ll lose access to key vehicle information during the reboot.

This reboot should be your first step when encountering an issue, especially if it’s due to the display being unresponsive or frozen. Other reboot types focus on restarting specific vehicle subsystems, so if a particular feature isn’t functioning correctly, a different reboot method may be necessary.

Sleep Reboot

Begin by unplugging everything from your vehicle, including any USB cables, devices, and the Rivian Guard USB drive. Remember to disconnect any items plugged into the Utility Panel and ensure the Gear Guard Cable Anchor (if applicable) is detached.

Next, unbuckle all seatbelts and remove any child seats or heavy items from the vehicle. If the vehicle is plugged in, disconnect it, then lock the doors. Make sure to keep all keys—including phone keys—away from the vehicle for at least 30 minutes.

This sleep reboot is simple and effective, although it could be more of a hassle, especially if you have car seats installed.

Full Reboot (1 Hour)

The full reboot resets all of the vehicle’s systems, essentially rebooting everything from the ground up. Important: Rivian support advises against performing this procedure multiple times in a short time period. You must wait at least an hour between full reboots to ensure all systems initialize correctly. Attempting back-to-back reboots may result in some vehicle systems not fully starting, which could require a service visit.

To initiate a full reboot, hold down the far-left button on the steering wheel and the emergency flasher button near the ceiling for 15 seconds. This will reset all vehicle systems. While it’s possible to drive immediately after the reboot, Rivian recommends letting the vehicle sit for at least an hour before resuming your journey to ensure everything is functioning correctly.
