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.
