I need to replace my battery in my GT3, and would like recommendations. I would love the weight savings of the Anti Gravity Battery, but I really want a no hassle solution. The car will be driven on weekends, and brought to occasional rally events. This is not a track car, it is more of a backroads ripper. Really appreciate all the expertise.

 

I'll just note that my no-name Amazon LiFePO4 battery has been excellent and it costs maybe 1/3-1/4 of what the antigravity does. The only thing it doesn't have is the key fob which I have zero interest in. 30Ah so it will last a solid month or two without any intervention if you aren't driving it. $200 or so and you can drop 40lbs.

 

I got the same one as brontosaurus based off of his previous posts. No issues with mine. Saved a ton of money over the big named ones.

 

Does this one have an auto shut down built in if the charge drops below a certain point?

 

I'm happy with my Interstate AGM from Costco that has been in 3 different 996's since I bought it in 2001. When it dies I'm tempted to replace it with the LiFeP04 as well. My car is street only at this point so the weight loss won't make much difference to me but at least it will be easier to lift it into the car.

 

Yes, although I forget what the # is.

 

Interstate AGM.

 

I've got the same Amazon cheap LiFePO4 battery. Just started the car yesterday after sitting four months, started right up.
Don't yet have a lithium battery tender so I just disconnect the battery when the car is going to be sitting for a while.

 

Thanks so much for the reply's guys. I am going to give anti gravity a try for their little remote start stuff. If it doesnt work it was an expensive experiment. I actually bought one of the battery's yall recommended for another car and will try it, amazing that its same weight as anti gravity for 1/5th the cost.

 

Thanks for going with our stuff MF993, we know all you guys have options and budgets to try to work within, so we respect its the Customer choice. I can tell you our Antigravity Battery will work awesome and it not let you down at all, and if anything ever comes up you will find us here on Rennlist and my email is in the signature. We offer a money back guarenttee for 3 months if anyone isn't satisfied. Additionally, if you even have to use the RE-START wireless built-in Jump Starting once you will be blown away. No looking at the battery or any dinking around, just press the keyfob and you start the car and go. We get the most comments and emails and such on how this saved a Customers drive, or got them out of some dead-battery hassle.

Being blunt there isn't a way to compete on pricing with a Chinese Manufacturer building a product from a stricktly "cost" perspective and putting it on Amazon. Its not a market we are in because it not our objective, our niche is to develope best in class products, using the highest quality of Lithium Cells, BMS, and include new unique technology that benefits people such as the Wireless built-in Jump Starting. Additionally, some of the "comparative cost" is that you are getting a 30Amp Hour Battery in the Amazon Battery and we are giving you 40 Amp Hours minimum, so its a few things more when comparing pricing or apples to apple, but we won't win in a price comparison.

Antigravity Batteries are the battery that comes equipped in the new Mustang GTDs, the Pagani Utopia, and the Gunther Werks Porsches, as well as tons of Rennlisters and other Porsches since 2016. We are also quite big in the Racing scene at every level from Club Racing to World Class in most every motorsport. This is not to "sell" you on paying a higher price, they is to say we are relied upon to produce a product that works under the highest temps, highest workload, offering more power output and has to use the top tier of every component to achieve that. The OEMs, Race teams, and regular daily drivers rely on what we produce to work well in the harshest uses... so we can't start making "cost based" products, because for us the stakes are higher than a Amazon merchant.

 

I'll report back on how it goes! Excited to try your product. I actually just bought another car that has your battery in it already.

 

I think I'd rather have $800 in my pocket than another 10Ah but that's just me.

Same commodity cells different box.

 

Not the cells that I’d be worried about. Not worth risking a potential fire over a poor BMS design to save a few bucks. Maybe the Amazon battery is just fine but so many people have antigravity without issue that it’s worth the peace of mind to me.

 

LiFePO4 doesn't really have these problems and a BMS is about as simple as it gets. Even your standard lead-acid batteries can start fires. Drawing a line between spending more money and getting a safer product is pretty tenuous here imo.

 

I like these Odyssey batteries. Pretty low weight (24 LBS) and reliable. I keep the car on a trickle charger all the time. My prior Odyssey battery lasted more than 5 years before I decided to replace it with the current one.
