I'm excited to finally announce Supercar Garage ATL & the McMedics has another ground breaking innovation to share with the McLaren community.


The fragile McLaren Lithium-ion battery has always been a weakness of our beloved supercars.

I have personally owned several McLaren's since 2016 and have spent untold dollars & downtime when forced to replace bad batteries every few years. So frustrating!!!!

THE ISSUE:
The OEM battery has a built in computer that communicates the battery 'state of charge' via the CAN BUS system, and if the battery is broken or removed, the rest of the car misbehaves in very strange ways and will drive the owner crazy!

This has forced every McLaren owner until now to repeatedly buy the extremely expensive McLaren battery as the only way to keep the car functioning correctly when a battery malfunction occurs. This cycle seems to be average every 4-5 years.

And in recent months, this has forced McLarens around the globe to sit parked waiting on new batteries to become available due to worldwide shortages of the OEM battery.


THE SOLUTION:
Now we have a brilliantly simple solution that unhandcuffs you from the McLaren OEM battery.

With the addition of a simple to install, standalone module that correctly emulates the battery 'state of charge' via the CAN BUS system, you can now choose ANY type or brand of battery you desire for your McLaren.


Three possible configurations using the new Battery Emulator Module:

1) KEEP your OEM McLaren battery that still holds a charge and starts your car, but the internal computer has failed.

2) Use ANY aftermarket brand of Lithium-Ion battery you choose (I personally have used and like the Anti-Gravity Batteries brand).

3) Use ANY aftermarket brand of Lead-Acid battery you choose (This is the most cost effective choice, albeit with a weight penalty of about 40+ lbs of extra weight)


Below is a short video of the module and installation guide.



If you are interested in purchasing please contact us at the number below or visit us at SupercarGarageATL.com

It's great to have this available. My "fragile" OEM Lithium-ion battery is 11 years old, and showing no signs of its age. However, given McLaren's consistent raising of parts prices as our cars get older, I can see one of these in my future.

My suspicion is that leaving the battery on a tender, or "jumping" the electronics, shortens their life.

Not that it's an issue, particularly given the cost saving, but does the new module correctly report battery charge (for one or more of the types of battery)? Even if it's "just" keeping the McLaren software happy, that's a win.

Thanks,

Roger

Yes, It can report the power level on any battery.

A lead acid battery is fully charged at 12.5 volts, and a lithium-ion battery is fully charged at 13.5 volts.

So the only variation is the "days remaining" status of a lead acid battery reports at around "33 days", while lithium-ion will suggest "60 days" remaining.

The reality this is just "lip service" and either battery will have the same shelf life as the other.

Kevin, silly question but is there any benefit to installing this module, even if you don't need it (perhaps to have it available for future use)? Any negatives to doing this?
.......Awesome work around!!!

There is ZERO BENEFIT to adding this module to your car if you currently have a health working OEM battery.

You could purchase one and keep it to be ready "just in case"... only if you just want to have it "on stand by" for the day your battery finally expires... That would keep you from any potential down time should the need arise.

Thanks Kevin - now - if someone could develop a fully functioning, no subscription MDS for under $2k USD - that would be Nirvana......
