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 variety of 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 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 5-7 business days (maybe less) depending on model, time of year, order volume and various factors. If a battery needs to be built for a race or even with a limited amount of time, Braille is happy to offer High Priority / RUSH production in an attempt to meet the given time frame but is not guaranteed.
