Braille Intensity Carbon Lithium_ i48CX

The 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 and also BMW, Audi, C7 Corvettes and others for nearly a decade. 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 I48CX is the ultra-lightweight lithium upgrade in a common Group 48 size.
  • Max weight Savings (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 (less than 0.5% annual failure rate)
  • Over a decade of use in street & race vehicles & used by more professional race teams, car builders and race series globally than any other 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!!

NOTE: All lithium batteries are hand built in Sarasota, Florida and production lead time can be up to 2-3 business days (same or next day if in stock) depending on model, time of year, order volume and various factors.

This battery qualifies for FREE GROUND SHIPPING (does not include expedited shipping) when using the code: FREESHIP at time of checkout.
