The CTEK Lithium US has an advanced microprocessor designed specifically for Lithium-Iron (LiFePO4) batteries to maximize their performance land lifespan. There are 8 charging steps including a testing sequence to show if the LiFePO4 battery can take and retain the charge and a maximization step to restore full capacity of the battery. Using 4.3A of charge current, this charger can charge batteries from 5Ah to 60Ah and maintain batteries with up to 120Ah of capacity.
When the NSX is in the garage for an extended stay, the CTEK charger keeps the battery in top condition.
Our NSX is now over 35lbs lighter than it was before thanks to the AntiGravity Group-35/Q85 Lithium Car Battery. This is a significant weight reduction and performance gain to our already lightweight aluminum supercar.
Even though the AntiGravity Intelligent Lithium Battery will prevent itself from damage and always retain enough reserve power to jumpstart itself, its always a good idea to keep the battery in ideal charge conditions when not in use to extend the longevity and performance of the battery. The CTEK Lithium US has us covered in that department and their chargers have been amazing assets to have in any garage.
Stay tuned for the next installment of Project NSX!

Carbon fiber hoods, lightweight seats, and titanium exhausts all provide functions other than just being lighter. That makes it easier to justify than battery that provides only one function. And while 35lb for $650+ is actually a pretty decent deal when you get to really cutting weight in a car, its still hard to justify in whats commonly still mostly a full-ish weight street car. In a race/track car where dropping weight is a big priority, a lithium battery is definitely low hanging fruit.
Bigger thing is lithium batteries cause weird issues in lots of modern cars. People don’t wanna risk it and then be stuck with a $650+ lightweight paperweight.
What problems are people having with lithium car batteries? I’ve had mine for nearly five years and it’s running like a champ. (1) Weight loss, (2) lifespan, (3) slow discharge and (4) built in jump starter. How many additional functions does a carbon fiber hood have? Especially a non vented one.
car throws codes and/or electronics start glitching. the older the car is the less likely it is to have any issues…
venting/aero is one, looking cool is another…
for the record I’m not telling anyone not to get a lithium battery. just the article was like “why do people get this stuff over a lithium battery”, so I gave some reasons

Ok, I didn’t take that from the article, bit maybe I missed something or just read it differently. I honestly think carbon fiber looks tacky anymore and prefer it painted. Like sport bikes in the 80s that left the aluminum raw so people could see they had an aluminum frame. Once everybody had that they started painting the frames again. Let’s not even get into the fit and finish on most aftermarket carbon parts. Hood venting can be done far cheaper retaining the factory hood and adding in vents from Verus, singular, etc.
I honestly have not seen anything on glitches from lithium batteries. I have seen check engine lights after replacing a battery that the car didn’t recognize immediately. But if the lithium battery has a proper management system as the antigravity does, this shouldn’t be an issue. The fact that Porsche offers lithium batteries as an upgrade for some of their cars kinda reinforces how good of an upgrade those is.

Certainly, here’s a more concise version of the text you provided:
“I didn’t take that from the article, but perhaps I misunderstood or read it differently. Personally, I find carbon fiber looks tacky now and prefer it painted, similar to sport bikes in the 80s that showcased aluminum frames. Once everyone had them, they started painting the frames again. Aftermarket carbon parts often lack good fit and finish. Hood venting can be achieved more affordably by retaining the factory hood and adding vents from brands like Verus or Singular.
Regarding glitches from lithium batteries, I haven’t personally witnessed any. I have, however, seen check engine lights come on after replacing a battery that the car didn’t recognize immediately. But if the lithium battery has a proper management system, like the antigravity does, this shouldn’t be an issue. The fact that Porsche offers lithium batteries as an upgrade for some of their cars reinforces how good of an upgrade they are.
Oof, delete that please
Actually, don’t delete. I’m having a good laugh at it.
Im running one of the antigravity battery on my 2020 sti
on a day of 105-110 F the battery overheat and don’t crank until it cools down .
Happens to me couples times while I’m cruising park the car and want to turn it back on .
Battery won’t hold charge for more than 4 days I’m guessing that is one of the reason they keep it charging .
After spending $650 for the set up , I’m still thinking if it was the right decision .
You have a current drain somewhere in your cars electrical system that’s overtaxing the charging system and battery. Dash cam, stereo, short, etc. was changed most likely. Also, have you swapped batteries to see if the problem still exists?
