Braille's i48CX model is a standard height lithium upgrade for vehicles that are equipped with a Group 48 battery. This model has been used in hundreds of Porsche cars ranging from Cayman GT4 to air-cooled 911 models all the way up to GT3RS and GT3 Cup cars

Also successfully used by BMW, Audi, C7 and C8 Corvettes and other sports cars and exotics for over a decade. Direct replacement for Audi RS3 & TTRS; VW Golf 7/8 GTI, CS & R; Cupra Leon; Porsche Cayman 987 GT4 & Spyder, 997 GT3 & GT3RS, GT3 Cup, 997 GT2RS, 981/718 Spyder, GT4 & GT4 Clubsport, 991 GT3 & GT3RS, 911R; Toyota Yaris GR.

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 i48CX - 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!!
