The Tesla Megapack battery could be considered as one of the rising stars of the company. During the fourth quarter and full year 2023 earnings call, Tesla executives highlighted that the growth of Tesla’s energy storage business would outpace the growth of the company’s automotive division this year. A lot of this growth would be due to the Megapack battery, Tesla’s flagship energy storage product.
The Tesla Megapack battery is the company’s largest energy storage system. Designed for grid-scale projects, the Megapack is offered in two configurations: a 2-hour version offering 1.9 MW of power and 3.9 MWh of energy and a 4-hour variant delivering 1 MW of power and 3.9 MWh of energy. The Megapack has been quite successful so far, with the energy storage device being deployed in high-profile projects such as the 182 MW/730 MWh installation in Moss Landing, California, to the 150 MW/300 MWh system in New South Wales, Australia.
With installation charges, the 2-hour variant is priced at $2,081,060, while the 4-hour variant is priced at $1,865,370. Without installation charges, the 2-hour Megapack is priced at $1,278,860 and the 4-hour variant is priced at $1,227,090. Tesla’s estimated annual maintenance cost for the Megapack battery is $8,830, with the cost rising 2% per year.
The Tesla Megapack is primarily built in the Lathrop Megafactory in California, though another Megafactory is poised to be built in Shanghai this year. And as per a recent drone flyover from Tesla watcher Met God in Wilderness, who has been conducting drone flyovers of some of Tesla’s California facilities, it appears that the Lathrop Megafactory is currently hard at work producing the grid-scale batteries at scale.
At the time of the Tesla watcher’s drone flyover, a total of 326 Tesla Megapacks could be seen on the premises of the Megafactory. That’s quite a lot of Megapacks, with Tesla watchers estimating that the batteries in the facility’s holding lots are likely worth over $500 million. Considering that Megapacks are designed for easy transport and installation, it would not be surprising if many of the batteries that were spotted in the drone operator’s flyover were delivered within the present quarter.
The past year was a period of milestones for Tesla Energy, with deployments seeing a 125% increase compared to 2022. As per Tesla CFO Vaibhav Taneja, the company’s energy storage business is also seeing a rise in revenue. “Our energy storage business had another record year with deployments more than doubling and revenues increasing by more than 50%. This business is poised to again surpass our auto business in terms of growth rate in 2024. This has been in the works for quite some time with us laying the foundation a few years back by building our Mega Factory in Lathrop,” Taneja said during the Q4 and FY 2023 earnings call.

Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a massive beat on vehicle deliveries for the second quarter, delivering 489,126 vehicles and building 451,758 cars during the three-month span.
This was a major shock for those on Wall Street as they anticipated somewhere around 400,000 deliveries for the quarter, and showed Tesla still has plenty of demand for its vehicles around the world and in the U.S. despite losing the $7,500 EV Tax Credit last year.
Tesla Q2 2026 Earnings Results
- Non-GAAP EPS – $0.33 reported vs. $0.53 expected
- Revenues – $28.236 billion reported vs. $26.4 billion expected
- Free Cash Flow- -$1.092B
- Profit -$ 4.751B
Tesla (beat/missed) analyst expectations, so the market response to the company’s quarter is what we will look for next.
Tesla shares closed today down just over 1 percent, trading at $374.01.
In the past, it has been anyone’s guess with what Tesla shares will do after they report earnings. Strong quarters have resulted in sharp drops, while lackluster quarters have seen the stock shoot up considerably.
Tesla will hold its Q2 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.

Tesla is about to make parking in busy lots less stressful than ever
Tesla is about to make parking in busy parking lots at businesses and other points of interest less stressful than ever by allowing drivers more control over where they park and how, CEO Elon Musk confirmed on X.
Tesla has been working to improve the parking performance of vehicles utilizing the Full Self-Driving suite, but now it is looking to add more customization, allowing drivers to choose the specific space they park in, but also potentially the orientation the car pulls into the spot:
It’s coming soon
— Elon Musk (@elonmusk) July 21, 2026
Musk has reiterated on X twice over the past several weeks that Tesla is working to make things with the FSD suite based more on the driver’s specific preferences and behaviors that were seen in past drives.
Essentially, it sounds like if you tend to park away from a business to avoid other vehicles, Tesla FSD will soon recognize that preference of yours and start parking further away as well. Additionally, the prospect of assigned parking spaces has been something many owners have voiced concerns about.
Living in a community with assigned parking spaces makes using FSD incredibly difficult as it will rarely park in the correct spot when there are so many to choose from. This is also pertinent in work settings where there are sometimes assigned parking spaces.
The updates to Tesla’s Full Self-Driving suite in terms of listening to driver preferences with parking are also extending to routing. Tesla announced yesterday that with the release of its 2026 Summer Update, it was adding Automatic Navigation and Preferred Routes:

Tesla has always maintained the idea that any human input is bad input, and that, ideally, Tesla Full Self-Driving will always make the right decision. Of course, this is all in theory, but the issue is that so many of Tesla’s interventions have come because it does something that is not necessarily wrong, but perhaps not what the driver would prefer.
Taking these preferences into account will help Tesla alleviate some of the potentially unnecessary interventions that drivers perform.

Tesla starts preparing for Optimus in its smartphone app
Tesla is starting to prepare for the launch of the Optimus robot in its smartphone app, new coding strings show. Elon Musk has referred to Optimus as what will be the greatest-selling product of any kind of all time, and now, Tesla is getting ready for its launch.
Tesla’s smartphone app had several first-time mentions of the Optimus program, according to Tesla App Updates, who intially reported on the appearance. Here’s what they found:
A Dedicated “Robot” Phone Key Authentication
Tesla is working on a Bluetooth Low Energy, or BLE, authentication that is specifically for robots. This does not only apply to Optimus, though, as Robotaxi, which is Tesla’s autonomous ride-hailing platform, might also identify vehicles within the fleet as robots as well.
Tesla shows rapid teardown of Model S and X lines, paving the way for Optimus at Fremont
Essentially, pairing your phone as a key to anything Tesla identifies as a robot to a “whitelist” of authorized devices. Optimus, Robotaxi, or other products that fall into this category will only respond if the device trying to communicate with it is authorized.
This is a great security feature that will eliminate at least face-value and low-level threats.
Home Data Collection and System Alerts
This appears to be somewhat of a neural network for Optimus within your house. There will be a dedicated screen that asks for consent to collect both video and spatial data while Optimus performs in-home tasks. Everything from vacuuming, washing dishes, dusting, and other activities will be tracked.
There will also be a comprehensive alert system that will track everything from low battery to mechanical issues.
Other Changes
Most of the changes tracked in this particular app update are related to Tesla’s 2026 Summer Update, and include things such as image assets for new features, a preview of the new custom wraps feature, and other unique features.
