i48CS - Intensity Carbon Group 48 (MAX power & capacity) lithium battery

The 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 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!!
