Hi guys, sorry for the delayed responses, just getting ready to get info published over the next couple of days on the new batteries. In regards to estimating how long this will really depend on the application, what other accessories if any have been installed. So ballpark this could really range anywhere from one month up to two easily.

In regards to this output we would definitely say that is a bit on the high side but you would likely be okay. Odd that it would be both cars, one thing we'd suggest is see if there is any calibration available to make sure those are the actual readings. Typically we see 14.5-14.6

Will you have a Rennlist Group Buy on the first batch of the improved battery?

My 2019 RS has been patiently waiting for an Antigravity. I have finished all other weight reduction steps (remove fire bottle and tools, forged wheels, JCR Titanium muffler), car already has WP and PCCB, base radio, standard interior.

wow long discussion I have to be honest I could not read very in details everything.
Nevertheless I would be interested for my 991.2 GT3 too as currently I am looking for the Liteblox 26xx but, yes, that battery comes almost to 2k which is lot for a battery!!

However I finally need a battery where I dont need to care about recharging and so on. Consider that I am driving the car not as a DD and the winter in germany is a nightmare => the car is parked around 4-5months! than on the spring/sommer driven on a weekly base. So, what is the best option ?

by the way, how do you handle it with porsche in the US? here they are making us crazy, any smaller modification to the car results in the loose of the waranty/approved if oyu want one.

thx

Good morning guys, here's there intro from our recent post on the new battery. Please feel free to have a peak at the thread for more info as well. https://rennlist.com/forums/991-gt3-...m-battery.html

Hi All,

Scott from Antigravity Batteries, I wanted to drop some information on our NEWEST Lithium Batteries... yes they are actually ground-breaking.

ľ We wanted to make the new battery accessible for more Vehicles and Customers. We found many people just wanted the EXACT SIZE that fit in their car. So that is what we did, the new batteries are a DIRECT OEM FIT. Meaning it is the same size as your stock battery, so you will not need a special tray or any other adapters or modifications to mount them. Being this is a GT3 Forum you guys will mostly ever be concerned with the H6/Group48 size battery. So we did that size and also the H5 and H7. Plus we will have Group 35 ,and Group 51 and expand out from there. But the "H" sizes are used in most all the Porsches, and other Euro Sports Cars including BMW, Audi, Ferrari, Lamborghini, etc.... so these will fit them all.

ľ We have also made the batteries available in different amp hours. The Amp Hours Capacities available for the H6/Group48 model are 24Ah, 30Ah, and 40Ah. By offering different amp hours the Customer can choose a battery that is more tailored to what they are looking for. For example people who track and want the lightest weight possible might want the 24Ah (9.5lbs), a person who wants to have a solid Ah yet still benefit substantially from Lightweight can go with a 30Ah (11.5lbs) and a person who might have some Cameras, Radar Detectors and other stuff on the Car might want a 40Ah Battery (16lbs) TT Guys or SUV guys. Keep in mind if you use a 24Ah battery you will not have as much time that the car can sit in storage compared to a 40Ah model.

ľ SUPER COOL NEW FEATURE ALERT!!! So one of the ULTRA-COOL items we developed into this latest battery (yep, first in the world) is a WIRELESS KEYFOB REMOTE that is used to operate our RE-START built in Jump-Starting feature. If you are not familiar with our RE-START feature, its basically a built-in jump starting for the battery, so in the event you ever come back to a dead battery you can awaken the battery with the Keyfob and start the car and drive off. So in effect you would never be stranded with a dead battery.

- OK, let me set this up.... wait for it.......... Antigravity raises its arms in Triumph, applause from the smiling Porsche enthusiast crowd, some Unicorns dancing off to the side.... and states...... " WITH THIS KEYFOB, YOU WON"T EVER BE LOCKED OUT OF YOUR FRUNK AGAIN!" crowd goes wild... fade to black. Ok, so maybe not so exciting for some of you, but it is a big deal for some of us. . First day I got my GT3, on a battery swap I locked myself out of the frunk and cursed how stupid it was to have to go to the Fuse Panel and energize the car to open the frunk, so with the new Keyfob just press the button on the Keyfob, the Battery then awakens and energizes your car to be ready for a Start or you can just open the Frunk.

- Weight of the Batteries H6/Group48 Case @24Ah is 9.8 lbs , H6/Group48 Case @30Ah is (11.5lbs) , H6/Group48 Case @40Ah is (16.5.5lbs).

-Availability.... finished production will be at the end of February we expect to be shipping in first week of March. We are initially doing the 24Ah and 40Ah models, the 30Ah Version will not be in until April. I currently have 10 pieces of H6 @24Ah models and 10 pieces of H6 @ 40Ah that we have used to take pictures, and develop Marketing materials, some we will be sent Industry people, but unfortunately that is not enough to openly sell them yet. So early March if not a week before we can start shipping.

-Pricing... The prices will range from $679 for the 24Ah Versions going up to $829.99 for the 40Ah Versions. Feel free to compare that to our competitors... we are over 1/3 to 1/2 less cost with more advanced technology, built in protections that most don't offer, and just a more realistic and reasonable price point. We might offer pre-orders starting in week, but we are trying to get a hard landing date so we can make sure we ship when we say we will.

Some pictures are below... if you have any questions please let me know.
