eBayer Offering Tesla Model X & S Battery Upgrades For Just $15,000


Tesla Model X Battery Upgrade On eBay For $15,000

Interested in upgrading your Tesla Model X or S battery via eBay? Well, now you can…apparently.

For just $15,000, eBayer k-ash is offering Tesla battery upgrades for most versions of the X and S.

Here’s the item description for the upgrade on the X:

“We would like to offer a service of upgrading your Tesla Model X from 60D or 75D to a 90D version. The service includes the battery, labor and all necessary changes done to the car. At this price you will be expected to leave your old battery with us. The new battery will be no more than 12 months old with less than 10k miles on it. We will also give you a 7 year unlimited miles warranty on the new battery.”

“After the upgrade your car will have increased power and the dash will say it’s a 90 version.”

“We specialize in fixing and servicing Tesla cars for 3 years now.”

“Once we are ready for your upgrade, your car will have to be brought to our shop in Hickory, NC for one to two days.”

Tesla Model S Battery Upgrade

The seller seems to deal almost exclusively in Tesla parts (see eBay store here) and has a perfect 100% rating on eBay, so perhaps this deal is legit.

Speculative comments suggest that the seller may be in some way connected to North Carolina resident (check out his home here) and famous Tesla hacker Jason Hughes (website here), but we haven’t been able to confirm this possible connection.

Here’s a link to the eBay listing for the X and here’s the link for the S.

so where do the batteries come from?

Ohh wait.
Didn’t the 60’s and 75’s have fewer cells?

Maybe he is just taking cells from a salvage pack and adding them to a 60 or 75 pack.


“100 kWh pack has 516 cells per module. That’s 8,256 cells per pack, a ~16% increase vs the 85/90 packs.”

I had read in the past that Tesla uses “dead” cells in the lower capacity packs; no idea if things have changed…

“I had read in the past that Tesla uses “dead” cells in the lower capacity packs…”

That was just speculation. Here’s the reality: We know that, for example, the original S60 had fewer cells than the original S85 because the curb weight was lower. If I recall correctly, nearly 200 lbs less. That wouldn’t be the case if they were filling out the empty space in the pack with dead cells.

Exactly. Maybe it’s just me, but I’m not comfortable spending so much on an ebay upgrade. If anything does go wrong with the battery, who knows if the ebayer will still be around to honour the warranty. Plus if/when you eventually sell your car i doubt it will have the resale value of a 90D.

georgeS asked:

“so where do the batteries come from?”

My guess is that they’re using battery packs salvaged from wrecks. Presumably this is just a cottage industry. I doubt they are going to be doing a high volume business, so likely they can get all they need from salvage yards.

30 kWh for $15,000. That is a good deal.

Yes it is. So can he upgrade my 24 kWh Leaf to a 30 kWh pack for $3k? If so I might be interested!

Yeah, my 30 kWh leaf needs to go to the Zoe 40kwh. $3k and I’m in, $5k maybe?

I think the 90 packs had the upgraded anode with more energy density. It was the 100 that they squeezed in more cells and upgraded the cooling.

If these are salvage batteries it’s hard to imagine there would be a big enough supply

The screenshot says they only have a supply of 2 available. I would guess that’s because they are coming from salvages.

Won’t be in business in 2 years, let alone 7 years

If it is Jason Hughes then I wouldn’t be so sure. The guy is very smart and I think he has lots of money. You should go check out the links.

Hard to believe they would toss out 20k mile batteries from a turned in 60? Are they saying they take your existing battery add new cells? Since new 60 is really a 75, are they just adding 15kWhr to those?

2 scenarios:
1) they have enough 90 packs to so swaps sells old packs as 14 modules x Price: US $1,299.00
2) they have official supply of those holders for additional 2 modules so they add 2 modules from crashed cars packs or leftovers form swaps

Li-ion battery packs need to have their cells balanced, which means they need to have the exact same maximum voltage, which means they need to be the same age. Adding cells to an existing pack, and still having it balance, may be possible, but would be very difficult.

Most likely they are using packs salvaged from wrecks, without alteration, or with as little alteration as possible. Note the stipulation “The new battery will be no more than 12 months old with less than 10k miles on it.” That means the “new” battery pack is actually a used one.

The seller is in Hickory, NC. wk057???

Would be a great option to upgrade my RAV4 EV battery from the current 110 mile range to 200+. Also, add a fast charge port at the same time. My battery pack is already a Tesla unit so it should be interchangeable.

Price is good but is seems scketchy. We will have to keep waiting.

Ha, you beat me to the punch. I would TOTALLY updrade our RAV to 85kW and get Tony to add QC if it were $15K. I have no real desire for a Model X as it just attracts too much unwanted attention. I just want the range.

I think this is great and we need more of this for other car models.

I heard sometime ago on an EV News show that someone got a SmartEV from a junk yard and the car maker would not sell them the battery by itself to make the car run.

Hopefully this is the begging of the EV drive-train aftermarket and hot-rodding.

I’d say the likes of “white zombie” on youtube got that ball rolling.

Other than obvious concerns about something installed by a third party working correctly, and the difficulty of getting service if something goes wrong, and whether or not this will void the warranty…

Aside from all that, I would be concerned about getting those over-the-air updates from Tesla. Tesla Inc. will have the owner’s car registered as 60D or 75D, and so would presumably send them an update for that version. With the car “hacked” to be a 90D, will Tesla send the right update to the car?

If famous Tesla hacker Jason Hughes is involved in this project, as speculated in comments above, then I’d have a fair degree of confidence they’ve figured out how to deal with that problem, possibly with the blessing and cooperation of Tesla. After all, Elon has said positive things about “good hacking” of Tesla cars.

But otherwise, I would be extremely leery of handing a Tesla car over to some anonymous guy with a nameless auto repair shop. There’s not even any company name given in the ebay description!

Waiting for an 55 kWh pack to replace my 24 kWh 2012 Leaf.

Guess, I’ll wait longer.

Seems like a bad idea if you ask me…

unless I misunderstand the way the feedback works, a quick scan (first and last pages) didn’t show any that were from someone who purchased from the seller. maybe someone wants to dig a little more?

As more cars are out there opportunities like these will become more common. As batteries become cheaper I would think aftermarket entrepreneurs will develop big battery packs for all EVs. And ‘range extender’ second batteries that could add capacity.

It will be interesting to see, as the EV market grows, how the aftermarket for improved or replacement battery packs develops — or doesn’t. Certainly there is a potential for that market to grow to something more than the cottage industry featured in this article. But properly managing the battery packs’ BMS (Battery Management System), and having the BMS communicate properly with the EV’s power electronics, would require access to proprietary software from the auto maker, or a very reliable and sophisticated emulation of that by independently developed software. There might also be patent issues with replacement battery packs.

So, I’m not sure we’ll ever see this become more than a cottage industry, relying on salvaged battery packs from wrecked EVs, unless auto makers are willing to license their BMS software to aftermarket manufacturers.

In general, auto makers aren’t going to want to do that, because they want customers to buy a new car instead of upgrading the old one. It’s the same reason that EV makers generally don’t offer their own battery pack upgrade to their own cars.

wish they would modify these and sell them as battery banks for your home. That would be a great deal compared to what it cost for a power wall.


The model 60 and 75 have a lesser rear motor than the 85 and 90…

Be wary of a known hacker offering an “upgrade” – particularly if your vehicle is still under warranty.

Tesla should void warranties for vehicles with tampered software and hardware.

There is a big cottage industry refurbishing Prius battery packs, our local community college has a course in how to do it. No surprise it has expanded to Tesla. I have repaired/swapped a few Think battery packs myself.
