The Tesla Model 3’s battery pack was given a partial teardown treatment recently, thanks to the efforts of automotive veteran Jack Rickard and his team at EVTV. Rickard, a car enthusiast who conducts electric vehicle conversions, was ultimately impressed with how the Model 3’s battery was assembled, as well as the refinement of its design.

Rickard’s team was able to acquire the battery pack from a totaled Model 3. Upon removing the pack from the vehicle, the electric car conversion specialist’s interest was piqued by the covering of the battery modules. According to Rickard, the sections of the battery pack directly above the Model 3’s 2170 cells had a thin pad that was strangely wet.

This particular section mentioned by Rickard appear to be the “fluff” that Elon Musk mentioned during Tesla’s Q1 2018 earnings call. According to Musk, the fiberglass mats, which are placed on top of the battery pack, became one of the scenarios that proved human hands can work better than robots.

“They’re basically fluff. We tried to automate the placement and bonding of fluff to the top of the battery pack, which was ridiculous. ‘Flufferbot,’ which was really an incredibly difficult machine to make work. Machines are not good at picking up pieces of fluff. Hands are way better at doing that,” Musk said.

Another particularly compelling observation highlighted by Rickard was that the four modules of the Model 3 battery pack were not identical, with two modules featuring 25 cell groups in series and the other two featuring 23 cell groups in series. Rickard’s team did not tear down the battery packs down to its individual 2170 cells, but it was mentioned that each one of the cell groups includes 46 2170 cells that are connected in parallel. Overall, the vehicle appears to have a total of 4,416 2170 cells, at least for the Model 3’s long-range RWD configuration.

The Model 3’s battery weighs 1,054 pounds, which, according to the group, places the energy density of the pack at around 168 Wh/kg. The individual modules of the Model 3 battery are lined with a ribbon-like circuit that goes across the top of the modules and into a BMS board. The BMS boards are sub-boards that are installed on each module, and are, in turn, connected to a main board using only two pins.

Ultimately, the EVTV team was impressed with the Model 3’s battery, with Rickard even dubbing it as the “best battery ever built to date.” The electric car conversion specialist also noted that the Model 3 battery would likely be a favorite among the DIY community. Considering that Tesla is attempting to achieve a production rate of 5,000 Model 3 per week by the end of Q2 2018, Rickard noted that the electric car’s batteries would probably be abundant in the market. This bodes well for DIY enthusiasts like Rickard, who could utilize the modules as batteries for RVs, home battery units, and electric car conversions, among other projects.

Jack Rickard and his team’s observations about the Model 3’s battery are in line with the findings of Sandy Munro during his firm’s teardown of the vehicle. In a recent episode of Autoline After Hours, Munro dubbed the Model 3’s pack as the best in the industry, noting the .2 milliamp differential between each of the battery blocks.

“Nobody can balance batteries that close. Nobody. Nobody’s ever done that,” Munro said.

Tesla just unlocked sales to 50,000+ government agencies

It marks a significant step in expanding Tesla’s presence in the public sector, where procurement processes have traditionally slowed electric vehicle adoption.

Tesla just unlocked sales to over 50,000 government agencies by entering a new agreement with Sourcewell, a purchasing cooperative.

Tesla entered a new master purchasing agreement with Sourcewell, the largest government purchasing cooperative in the U.S. This will enable streamlined sales of its EVs to more than 50,000 U.S. public entities. Tesla entered Designated Contract 0813525-TES, and the agreement covers Model 3, Model Y, and Cybertruck, and potentially other vehicles the company could release.

It marks a significant step in expanding Tesla’s presence in the public sector, where procurement processes have traditionally slowed electric vehicle adoption.

The deal allows eligible agencies, including cities, school districts, state governments, and higher-education institutions, to purchase Tesla vehicles directly through Sourcewell without conducting their own lengthy competitive bidding or request-for-proposal (RFP) processes.

Pricing is pre-negotiated and capped, providing transparency and predictability. Agencies simply register for a Sourcewell account online or by phone and place orders under the existing contract. This cooperative model aggregates demand across thousands of members, reducing administrative costs and time while ensuring compliance with public procurement rules.

For Tesla, the agreement removes major barriers to government fleet sales. Public-sector procurement cycles often stretch 12 to 18 months due to bidding requirements and committee reviews.

By securing the master contract, Tesla gains immediate, simplified access to a massive customer base that previously faced friction in adopting EVs. The company highlighted in its announcement that the partnership will help these 50,000-plus agencies “save thousands of $$$ in operating costs for their vehicle fleet over time” through lower maintenance, energy efficiency, and the elimination of tailpipe emissions.

The initial four-year term runs through November 13, 2029, with options for up to three one-year extensions, offering long-term stability for both parties.

Sourcewell’s role is central to execution. As a cooperative purchasing organization, it negotiates and manages vendor contracts on behalf of its members, then makes them available nationwide. Participating entities contact Tesla’s dedicated fleet team or Sourcewell representatives to complete purchases, bypassing redundant paperwork.

This structure accelerates fleet electrification while maintaining fiscal accountability—agencies receive pre-vetted pricing and terms without reinventing the wheel for each vehicle order.

The partnership positions Tesla to capture a larger share of the public fleet market, where total cost of ownership often favors electric vehicles once procurement hurdles are removed.

For government buyers, it translates to faster deployment of sustainable fleets, reduced long-term expenses, and alignment with environmental mandates. As more agencies transition, the contract could contribute to broader EV infrastructure growth and taxpayer savings across the country.

How much of SpaceX will Elon Musk own after IPO will surprise you

SpaceX’s IPO filing confirms Musk will maintain his voting power to make key decisions for the company.

Elon Musk will retain dominant voting control of SpaceX after it goes public, according to the company’s IPO prospectus that was filed with the SEC. The filing reveals a dual-class equity structure giving Class B shareholders 10 votes each, concentrating power with Musk and a handful of other insiders, while Class A shares sold to public investors carry one vote.

Musk holds approximately 42% of SpaceX’s equity and controls roughly 79% of its votes through super-voting shares. He will simultaneously serve as CEO, CTO, and chairman of the nine-member board after the listing. Beyond that, the filing includes provisions that may limit shareholders’ influence over board elections and legal actions, forcing disputes into arbitration and restricting where they can be brought.

The case for Musk holding this level of control is grounded in SpaceX’s actual history. The company’s most important bets, from reusable rockets to a global satellite internet constellation, were decisions that ran against conventional aerospace thinking and would likely have faced resistance from a board accountable to investor gains. Fully reusable rockets were considered economically irrational by established industry players for years. Starlink, which now generates over $4 billion in annual operating profit, was widely dismissed as financially unviable when it was proposed. The argument for concentrated founder control seems straightforward, and the decisions that built SpaceX into what it is today required someone willing to ignore consensus and absorb years of losses.

For context, Musk’s position is significantly more dominant than Zuckerberg’s at Meta. The comparison with Tesla is also worth noting. When Tesla did its IPO in 2010, it did not issue dual-class shares. Musk has only recently pushed for enhanced voting protection, proposing at least 25% control at Tesla in 2024 after selling shares to fund his Twitter acquisition left him with around 13%.

SpaceX has clearly learned from that experience and structured the IPO differently by planning to allocate up to 30% of shares to retail investors, roughly three times the typical norm for a large offering. The roadshow is expected to begin the week of June 8, with a Nasdaq listing rumored to be a $1.75 trillion valuation and a $75 billion raise.

Tesla is bolstering its smartphone App with a series of new features to streamline operations for owners. The new additions include fixes to safety, its in-house insurance offering, and storage management for Dashcam clips.

The Tesla Smartphone App is one of the biggest and best features and advantages owners have. Everything from moving the vehicle with Summon, to getting Navigation sent to the car, to preconditioning the cabin can be done with the Tesla App.

But in classic Tesla fashion, the company is aiming to improve the offerings of the app, and it is doing so with a handful of new features. They were first discovered by Tesla App Updates.

Tesla Insurance – Safety Score 3.0

This is truly part of the Spring 2026 Update, but Tesla has now given more transparency on how FSD has saved people money on their premiums.

Additionally, Tesla is now automatically awarding a Safety Score of 100 for every mile traveled on Full Self-Driving (Supervised).

Update Tracking

Updates traditionally appear on the App or on the Center Touchscreen in the car. There is nothing better than seeing that Green Arrow at the top of the screen, or opening your app and seeing that there is a Software Update available.

Now, there will be no need to manually check the app and initiate the download. Tesla is enabling a new feature that will automatically download updates for you.

Storage Management

Your USB drive can now be remotely formatted, and old Dashcam clips can be deleted straight from the phone. When you record a lot of things using the Dashcam feature, that storage fills up pretty quickly.

Now, manually deleting the Dashcam videos is easier than ever.

Trailer Light Test

This is perhaps the coolest and most crucial addition to the Tesla App, as those who tow and haul will now be able to trigger a diagnostic light sequence from the app while standing behind your trailer to ensure the brake lights work.

Verifying your trailer lights are connected properly and operating normally and as intended is normally a massive hassle.
