Rivian Max Pack battery options have appeared in the R1S configurator and R1T inventory shop. It hints that Rivian may have started producing units with Max Pack battery options. 

Rivian Forum members first noticed the availability of the R1S Max Pack in its configurator on Monday. At the same time, they also noticed that the R1T Max Pack option appeared in Rivian’s inventory shop, although customers noted that it was not clickable.

Further inspection of the configurators revealed that the Max Pack battery is available with only Rivian’s Performance Dual Motor AWD drive system for the R1T pickup truck and the R1S SUV. Rivian’s Performance Dual-Motor AWD drive system is an additional $5,000 for both R1 models. 

The Rivian R1T’s Max Pack battery has an EPA estimated range of 410 and will cost an additional $16,000. The EV automaker noted that the R1T Max Pack must have 21-inch tires to get 410 miles of range. Rivian estimates that the R1T Max Pack’s range drops to 380 miles per charge with 22-inch tires and 355 miles per charge with 20-inch tires. The Max Pack battery for the R1S costs the same and has an EPA estimated range of 400 miles. 

An R1T Performance Dual-Motor AWD costs $94,000 with the Max Pack battery and basic options, like 21-inch wheels and gray paint. Meanwhile, the R1S Performance Dual-Motor AWD costs $99,000 with the Max Pack battery and basic options.

Some Rivian Forum members wondered if paying an extra $21,000 for an R1 Max Pack order is worth it. 

“Before people gripe about how it’s “not worth it,” keep in mind that it’s likely more expensive because every battery cell has more advanced chemistry.

It’s not just more large pack cells. You’re getting more range without any added battery pack weight. IMO, this is significant. And the max pack cells probably have a different charging curve than the large packs. We’ll have to see!” Said DuoRivian.

“I know a bit about battery chemistry. And the only mass-market 21700 is a 5800ah model (Large Pack is 5000), which you can use to figure out exactly what the extra kWh is. And 16k or 10k, it’s still insanely overpriced.

Trust me, I’ve been following this for a while as Rivian has slowly walked back on the Max Pack promises. Oh, and that cell change? Sure, it might be a different charging curve (my guess is worse, not better), but get ready for some negative side effects, like steep degradation.” Said Supratachophobia.

Tesla Megapack powers $1.1B AI data center project in Brazil

By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.

Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.

The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.

According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.

“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”

By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.

“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.

The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.

The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.

Starlink powers Europe’s first satellite-to-phone service with O2 partnership

The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools.

Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.

The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.

Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.

The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.

By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.

Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.

Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.

For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.

Elon Musk’s Starbase, Texas has been included in an $84.6 million coastal funding round announced by the Texas General Land Office (GLO). The funds mark another step in the state’s ongoing beach restoration and resilience efforts along the Gulf Coast.

Texas Land Commissioner Dawn Buckingham confirmed that 14 coastal counties will receive funding through the Coastal Management Program (CMP) Grant Cycle 31 and Coastal Erosion Planning and Response Act (CEPRA) program Cycle 14. Among the Brownsville-area recipients listed was the City of Starbase, which is home to SpaceX’s Starship factory.

“As someone who spent more than a decade living on the Texas coast, ensuring our communities, wildlife, and their habitats are safe and thriving is of utmost importance. I am honored to bring this much-needed funding to our coastal communities for these beneficial projects,” Commissioner Buckingham said in a press release

“By dedicating this crucial assistance to these impactful projects, the GLO is ensuring our Texas coast will continue to thrive and remain resilient for generations to come.”

The official Starbase account acknowledged the support in a post on X, writing: “Coastal resilience takes teamwork. We appreciate @TXGLO and Commissioner Dawn Buckingham for their continued support of beach restoration projects in Starbase.”

The funding will support a range of coastal initiatives, including beach nourishment, dune restoration, shoreline stabilization, habitat restoration, and water quality improvements.

CMP projects are backed by funding from the National Oceanic and Atmospheric Administration and the Gulf of Mexico Energy Security Act, alongside local partner matches. CEPRA projects focus specifically on reducing coastal erosion and are funded through allocations from the Texas Legislature, the Texas Hotel Occupancy Tax, and GOMESA.

Checks were presented in Corpus Christi and Brownsville to counties, municipalities, universities, and conservation groups. In addition to Starbase, Brownsville-area recipients included Cameron County, the City of South Padre Island, Willacy County, and the Willacy County Navigation District.
