Our Braille i48CS model is a standard height lithium upgrade for vehicles that are equipped with a Group 48 battery. This model has DOUBLE the power & capacity of the ultra lightweight CE & CX models and all versions have been used in hundreds of Porsche cars

Models ranging from Cayman GT4 to variety of 911 models all the way up to GT3RS and GT3 Cup cars and also BMW, Audi, C7 & C8 Corvettes and other sports cars & exotics for over a decade. Direct replacement for Porsche 991 Turbo & Turbo S, 991 GT2RS, 992 Turbo & Turbo S; Ferrari 458, 488 GTB & 488 Pista, F8 Tributo.

At only 10 pounds, it offers more cranking power than the OE Porsche lithium battery and is a true "race grade" product compared to the majority of "consumer grade" (lesser) products on the market.

There is a reason that Braille lithium batteries have an annual failure rate of less than 1/2 of 1% in road and factory race cars and those are almost always linked to abuse, improper maintenance or other factor that could damage any battery!

Braille lithium race batteries are used by more professional race teams, car builders and race series globally, than any other lithium battery on the market!!

  • Braille I48CS - the ultra-lightweight Group 48 size lithium upgrade
  • Max weight Savings!! (Only 10 pounds vs 45-60 in a lead battery)
  • 100% compatible with ALL standard charging systems
  • Can be used in total loss (no alternator) applications
  • True 'Race Grade' lithium battery Made in USA (Sarasota, Florida)
  • Most reliable lithium battery on the market
  • Braille Lithium delivers a higher, cleaner voltage which improves the performance of every electrical component and has shown to provide: quicker starting, improved management & data logging performance, less horsepower draw from the alternator due to efficient charging (5 times faster than lead), will last 3-5 times longer (especially under the harshest environments), much more reliable, all of this on top of the significant weight savings.

    They also don’t self-discharge, so if the battery is disconnected (no draw or via power disconnect switch), they can sit for over a year and still have over 13 volts to start the vehicle. To get all these benefits in one simple step makes it a very cost effective upgrade!!

    Comfortable and Supportive, but Adjust the Filling
    Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)
    I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok. One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable. Overall, great quality, comfortable, and worth the purchase.

    BEST PILLOWS EVER!!!
    Color: White-cooling Basic, Size: Queen(Pack of 2)
    I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person. You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

    Top of the line, best pillows Ive ever had
    Color: White-cooling Basic, Size: Queen(Pack of 2)
    These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D

    Weird smell
    Color: White-cooling Basic, Size: Queen(Pack of 2)
    The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.
