Braille i48CS Intensity Carbon Lithium Battery. The i48CS model is a full height, stock battery sized, lithium upgrade for vehicles that are equipped with a Group 48 battery, but features DOUBLE the power and capacity of the CE and CX lightweight models. 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 19.9 pounds, it offers more cranking power than the OE Porsche lithium battery and is a true 'race grade' product, compared to the majority of lesser, 'consumer grade' products on the market. Braille's Lithium-Ion Technology produces a battery with more power that is lighter, stronger and more efficient.
Max weight Savings, around 19.9 pounds Vs. 45-60lbs for a lead battery100% compatible with ALL automotive standard charging systemsCan be used in total loss (no alternator) racecar applicationsTrue 'Race Grade' lithium battery, Made in USA (Sarasota, Florida)The most reliable lithium battery on the marketOver a decade of use in street, race vehicles and used by more professional race teams, car builders and race series globally than any other lithium battery on the market! What's more these batteries 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.

Braille Intensity Carbon lithium batteries come in 3 common Group sizes (34, 48 and 49) as well as a low-profile (2 inches shorter) version in the CE model. Direct drop in upgrade that is 100% compatible with ALL standard charging systems and can also be used in race cars with a 'Total Loss' (no alternator) setup. A lithium charger is required to keep batteries charged on vehicles with a parasitic draw (computer, alarm, etc.) but with no draw, Braille lithium batteries can sit for a year and still be at 90% state of charge. Braille is the only American made 'Race Grade' lithium battery on the market used by more OEM factory and purpose built race cars, professional race series and also spec lithium battery in several cases around the world!
With an annual failure rate of less than 1/2 of 1% (those caused by abuse, improper maintenance, etc.), you can have the most reliable lithium battery on the market with over a decade of actual use on race and street cars for any vehicle you have!! There is a difference between the other 'consumer grade' lithium batteries with a bunch of 'bells and whistles' that don't match up to the performance and reliability of Braille 'race grade' batteries....our pedigree, racing history and customers speaks for itself!! Call Raceparts USA with any questions you may have as to which battery is right for your vehicle based on goals, usage, goals, etc.
