Decoding Your Tesla Battery Pack Version
Identifying Your Tesla Battery Pack
Did you know the Tesla Model S battery comes in either an A, B, D, or E pack?
Your Tesla battery pack information is found on a sticker affixed to the front right side of the battery pack that can be seen when looking under your car from just behind the front right (passenger side) wheel.
The first and arguably the most important part of the label is the top portion which indicates the size of your battery pack. This is useful when validating that you received the correct battery ordered. The next piece of information which may have some potential value is the model of the battery indicated by the last letter trailing the part number. In my case I have the “D” battery pack.
Tesla Battery Pack Version
The main notable difference in features between battery pack versions occur between the A and B packs. An improvement to the cooling system of the battery pack was made starting with the B packs that allowed for faster Supercharging. Those with A battery packs can only Supercharge at a maximum of 90kW while those with B battery packs and later can Supercharge at 120kW, or possibly higher.
Tesla Model X P90D(L) 90 kWh Battery Pack
According to the TMC Wiki that tracks Tesla battery pack part numbers, the basic pack versions can be decoded through the following:
- 1071941 is the 90 kWh pack from a Model X P90D(L)
- 1063792 is a new 90 kWh pack
- 1014114 is a new 85 kWh pack
- 1020422 is a new 60 kWh pack
There’s a large variation of part numbers which may contain notable differences that the community has yet to identify. Or it may simply be an indicator for a refurbished pack versus a factory new one.

Barring formal confirmation from Tesla, the working theory is that battery pack versions A, B and D are equivalent to model years of the car. They’re evolutions of the same core battery pack with each subsequent letter being better than its predecessor. Superchargers capable of greater than 120kW are just starting to emerge. The 100th Supercharger, recently installed in NJ, was a 135kW Supercharger.
D battery packs began shipping sometime in the second half of 2013 and represent the latest versions to be installed. If you have a D pack rest assure that you’ve got the latest.
So far there have been no reported differences between the B battery pack and the D battery pack in terms of charge rates or performance, but the current theory is that the B pack may be limited to charging at 120kW while the D pack may be capable of supporting 150kW.
Summary
If you purchased a Model S in late 2013 or 2014, you’re most likely using the latest and greatest battery pack version from Tesla. However, if something should ever go wrong and you’re given a replacement battery pack by the Tesla Service Center, make sure you do not receive a refurbished A pack or any pack labeled with a version older than your existing one.
If you don’t know the version of your battery pack, do yourself a favor and go take a picture of it and save it for your records. You might be thankful you did one day.

President Donald Trump buys a Tesla at the White House – Here’s which model he chose

U.S. President Donald Trump was greeted by a convoy of Tesla electric vehicles today at the White House after he said last evening he would be buying one of the company’s cars in support of Elon Musk.
A variety of Tesla EVs, including the Model S, Cybertruck, and Model Y, all arrived in Washington on Tuesday around lunch time where the President sat in, examined, and mulled over which car he would choose. White House Press Secretary Karoline Leavitt told reporters today that President Trump would be paying “full market price” for the vehicle.
CEO Elon Musk was alongside Trump to help make his decision:
Which Tesla did President Trump Choose?
After mulling the decision for several minutes, President Trump seemed to have gravitated toward the Tesla Model S Plaid in Deep Red, the company’s quickest and most luxurious offering, suitable for the leader of the U.S.
Trump said:
“The one I like is that one (Model S). And I want that same color. I’m going to give [Tesla] a check. I don’t want a discount.”
According to images shared from Washington, it seems Musk brought two Model S vehicles — one in Deep Red and another in Deep Blue Metallic — knowing that the President would probably choose that vehicle, but was unsure about the color.

President Trump’s Comments on Tesla and Elon Musk
President Trump has truly gained a meaningful working relationship with Musk, who he has called “a genius” and “brilliant” on several occasions. Regarding Tesla, the President said:
“Tesla’s a great company; They’re American cars, it’s American made. He employs thousands of people. He has the most modern plants in the world.”
In regards to the Tesla lineup, President Trump said:
“I know people that have these cars; It blows them away. They love them.”
When talking about the polarizing design of the Cybertruck, he said:
“In terms of imagination, and I think I have a pretty great imagination, who else but this guy would design this and everybody on the road is looking at it. As soon as I saw it, I said, ‘That’s the coolest design.’ You gotta give him (Elon) credit.”

Tesla makes a decision on the future of its flagship Model S and Model X

Tesla has made a decision regarding the future of its flagship vehicles, the Model S and Model X, which both have been sticking around for “sentimental reasons” and have no true alignment with the company’s future goals of growth.
The Model S and Model X were Tesla’s first two vehicles to be offered to the public.
They were essentially fundraisers for future, mass-market, affordable models, according to Elon Musk’s “Tesla Master Plan,” but their ability to still attract some buyers thanks to the performance of the Model S or the space of the Model X keeps them lingering.
But speculation regarding the vehicles’ true place in the expanding Tesla lineup has been persistent. With the vehicles, which have been grouped in with the Cybertruck in its quarterly delivery releases, only amounting to 23,000 deliveries in Q4, there are questions as to whether it is still worth keeping them around.
Tesla’s VP of Vehicle Engineering, Lars Moravy, said on the Ride the Lightning podcast yesterday that there are currently no plans to eliminate the Model S and Model X from the lineup.
When asked about whether there were plans for the Model S and Model X moving forward, Moravy replied:
“Just give it a minute. We’ll get there. The upgrade a couple of years ago was bigger than most people thought in terms of architecture and structure of the car got a lot better, too. But, we’ll give it some love later this year and make sure it gets a little bit…you know, with the stuff we’ve been putting in 3 and Y. Obviously, with 3 and Y, the higher volume stuff, you’ve gotta focus there.”
He confirmed that the two vehicles were not going anywhere “anytime soon.”
? When @DMC_Ryan asked Lars Moravy if Model S and Model X have some updates coming, the Tesla VP of Vehicle Engineering said:
“Just give it a minute. We’ll get there.”

Moravy said the Model S and Model X are great consider when you consider autonomy and the robotaxi use: the Model S due to its overall quality and the Model X because of its interior space.

Tesla is offering a crazy Supercharging incentive on its two ‘sentimental’ vehicles

Tesla is offering a crazy Supercharging incentive for those who choose to buy two vehicles that CEO Elon Musk said the company is keeping around for “sentimental reasons” a few years ago.
Tesla Supercharging incentives are pretty hard to come by, and it is hard to tell when the company is going to offer them. Usually, they are used to move vehicles and nudge consumers toward purchasing one model over another.
However, Tesla sometimes offers Supercharging incentives at random times for no real reason other than luck of the draw.
However, Tesla is using the Supercharging incentive to help move two of the cars that are low-volume sellers, but are kept around for what Musk called “sentimental reasons” in 2019.
Tesla is offering free Supercharging for those who choose to purchase or lease a new Model S or Model X.
The offer is good for the life of your ownership or lease. Tesla talks more about the terms on its website:
“Customers who purchase or lease a new Model X (or Model S) are eligible for free Supercharging during your ownership of the vehicle. Offer is tied to your Tesla Account and cannot be transferred to another vehicle, person or order, even in the case of ownership transfer. Used vehicles, business orders and vehicles used for commercial purposes (like taxi, rideshare and delivery services) are excluded from this promotion. You are still responsible for Supercharger fees, like idle and congestion fees, when applicable.”
This is a great promotion to attempt and move some of Tesla’s vehicles, especially two that the company only keeps around because they are two of the company’s foundational, flagship cars.
Musk said in 2019:
“I mean, they’re very expensive, made in low volume. To be totally frank, we’re continuing to make them more for sentimental reasons than anything else. They’re really of minor importance to the future.”
Tesla has not released a major update to the Model S or Model X in a few years. In 2022, it launched the Plaid configuration, but it has not received any true modifications since then, leading some to believe they could be sunsetted in the future.
For now, it seems they will be sticking around, but Tesla is still adjusting the prices and incentives of the two vehicles. Earlier this week, Tesla pushed the Model X’s price in the U.S. up by $5,000.
