Yes.

I actually have a dead as a doornail porsche oem LION i'm going to see if it will charge. Will hook up CTEK Lithium charger to it, and run an extension cord in middle of back patio in case we have meltdown :-)

As you probably know, traveling with consumer electronic and medical devices containing lithium cells or batteries (e.g. watches, calculators, cameras, cell phones, laptops, camcorders, hearing aids, etc.) is allowed onboard as carry-on. Spare lithium batteries are allowed as carry-on only, and must be individually protected to prevent short circuits.

Tips to properly transport spare lithium batteries:

• Pack spare batteries in carry-on baggage.
• Keep spare batteries in the original retail packaging to prevent unintentional activation or short-circuiting.
• If original packaging is not available, effectively insulate battery terminals by isolating spare batteries from contact with other batteries and/or metal.
• Specifically, place each battery in its own protective case, plastic bag or package, or place tape across the battery's contacts to isolate terminals.
• Take steps to prevent crushing, puncturing, or putting a high degree of pressure on the battery, as this can cause an internal short circuit, resulting in overheating.

Size Limits for Lithium Batteries:

Passengers are permitted to travel with lithium ion batteries that contain a maximum of 160 watt hours per battery. Any lithium ion battery containing more than 160 watt hours is prohibited from carriage on all passenger aircraft. Lithium ion batteries installed in a personal electronic device can be transported as checked or carry on baggage. Lithium ion batteries not installed in a device (spares) must be in carry-on baggage and no more than two (2) spares between 100 and 160 watt hours are allowed.

No, you cannot check-in a loose lithium battery, as per TSA or CAA.

I'm having mine shipped by specialist courier to Southeast Asia as LiFePO batteries are classed within the highest haz-mat category. An individual cannot arrange for shipment, it needs to be a registered company with appropriate credentials to create a shipping account with the courier for haz-mat items. It is not simple.

Dead Li batteries usually do not come back because once they are fully discharged, they start destroying themselves inside irreversibly, unlike led batteries that can be brought back with a clever charger.

Any updates on how these batteries are performing? Any problems since installation? Any incompatibilities with start/stop tech?

How to install a Lithium Battery? Can I just unplug the original battery and plug in the (porsche) lithium battery?

I would also be interested in a group buy. I have a 991.2 GT3.

No updates? Anybody?

Anyone actually feel the difference with the reduced weight?

Hey all,

Scott from Antigravity here... sorry I haven't posted in a while I actually thought the thread was dormant because I did not get any notification of postings...

A couple things...

1- Its been a few months since the Group Buy, I think there were roughly 50 sales from that.. but since that time we've also sold about 500 to others... about 1000 in the market in total over the last 10 months. Many of those to more Porsche guys but also other sports Cars, Vettes, Vipers, Mustangs few Lambos and such. 2018 Vette won't work because the vette Teriminal is so big it covers the RE-START button... but only on that particular car.

2- We've not heard any negative responses in terms of operation of the battery, the main issues for some cars was just that the battery is not a stock size. But it was not intended to be a "stock" size. We wanted it more compact. But we are introducing Stock size in January 2019. But as far as we are concerned it has been just a solid battery for everyone. No reports on anything negative happening.

3- I think we've had about 4 reports of flags, none on GT3s but a few Turbos.... and ultimately those 3 came down to the Users having the 24 hour Cameras on the Cars and running them into the cars system, but when they went with the dedicated Camera Battery packs and took the Camera off the Cars system the flag went away. I have no idea why, but assume they had it hooked to a circuit in the car and it effected the way the car saw the voltage being relayed to the system, but when they went with those dedicated Battery packs for the Cameras the issues stopped. A few also had Radar detectors as well as the Camera. But all those flags were resolved, and I have not heard back from anyone.

4-As I said above we had over 50 participants in the Group Buy... I have not heard anything negative, and I assume they would be posting back on here or to us if they had experienced anything bad. I would also like to know from any of you who have participated in the Group Buy, or own the battery have to say. I've talked to many of you through email, and I also met some of you at the Porsche Reunion where we were set up. But keep in touch. As always contact me if you have any questions scott@antigravitybatteries.com.

5- About 4 people were frustrated or did not understand why the Optimate Charger kept the green light flashing indicating it was charging. We do not manufacturer the Optimate, but I told the Customer not to worry, it does it on my personal charger and all I can say it it is charged fine and not hurting the battery. We contacted Optimate and they did not have a great answer I can pass on, but no one else reported the issue and it does not hurt anything on the battery. But as I stated earlier in the thread, if you are driving the car once every 6 weeks don't bother putting it on the charger... UNLESS you have some other issues causing a fast Parasitic draw like Cameras or aftermarket Bluetooth chargers and such. The fact is all the 2014 and later 911 variants all seem to be able to do about 6- 9 week with the RS-30 sitting in the car and starting the car right up after that long with no issues, provided you don't have additinal non-stock electronics.

6- You DO NOT need to reprogram the PIWIS to run the RS-30.. I say this because I have a 2016 GT3 RS and have NEVER done it, and there has never been anything odd, or a flag. Additionally we have so many Customers that also have not done it and have NO issues. Yes I know some of you HAVE changed it and also not reported issues, so from our experience either method works perfectly fine with our Battery. Now the facts about this are.....I have the Porsche Bulliton document that states that you should change to the LITHIUM PIWIS setting in the Cars using THEIR battery. The document goes on to explain that it reduces the output of the Alternator to 13.8v. But that is honestly LAME!!! Our lithium Battery, can easily handle the standard charging pattern of Modern or older without issue. So while I understand Porsche's thinking, that a lower state of charge makes a battery last longer, but the fact is it's boloney because the BMS of the battery and the Lithium Cells they use should easily handle normal Charging Curves that don't exceed the batteries thresholds, and being that Lithium is rated at TWICE the life cycles of Lead there should be a very minor change in the longevity of the battery by charging it at a lower voltage. Additionally lithium can handle up to 15v. So I call Porsche out on just providing a crappy battery... the no boloney facts are the Porsche Lithium Battery is failing. I've talked to 3 dealerships and about 5 techs and they all say they have gotten them back from angry customers because they failed within a few months to a year, and that they DON"T recommend them to their Customer anymore. So that is pretty bad because you would think they would have a good supplier for their $3500 dollar battery. If anyone wants to sell us one that is ruined I will disect it and see what is up, because if you paying that kind of money for a Battery and its a quality Lithium Battery you should be getting about 7-8 years out of it.

7- We have some other very cool stuff coming in the upcoming months (Early 2019) ... just doing some testing. For example OEM exact fit sizing for the H5/Group 47 - H6/Group48 - H7/Group49 models.... and they will have a little more Capacity at 40Ah and up. But a little more weight about 2.5 lbs, but made for those who want the exact Lead/Acid replica size it will be good, and they will be 10 and more Amp Hpurs. The RS-30 will still be the go-to for most weight loss in a compact size, but we wanted to offer the OEM sizing Alternative stuff with a bit more capacity for those who have more electronics or don't want the ultra lightweight stuff. And these will also be set to work more in the parameters with the STOP/START features of the Turbos.

8- For Black Friday Weekend we will be doing another Group Buy on the RS-30 with Charger and Tray. I'll post up about that later with a new Thread.

Lithium batteries should be stored on a maintainer. Once the voltage gets too low, they are toast.
