Description

The Braille Intensity i35X is an ultra-lightweight lithium upgrade designed to fit the common Group 35 battery size, offering a direct replacement for vehicles such as the Nissan 350Z & 370Z, Subaru Impreza WRX/STI & BRZ, and Toyota GT86 & GR86, among others that utilize the same battery dimensions. This 'Race Grade' lithium battery, manufactured in the USA, provides a higher, cleaner voltage, which enhances the performance of all electrical components. Benefits include quicker starting, improved data logging performance, and less horsepower draw from the alternator due to its highly efficient charging capabilities – up to five times faster than lead-acid batteries. The i35X is built for longevity, expected to last 3-5 times longer than lead-acid equivalents, especially in harsh environments. With a weight of just 10 pounds, it offers substantial weight savings compared to conventional lead-acid batteries (45-60 lbs). The i35X is 100% compatible with all standard charging systems and can also function in total loss applications where an alternator is not present. Its advanced chemistry allows it to hold over 13 volts for over a year even when disconnected, ensuring reliable starting power.
