Whether you're building a dedicated track weapon or upgrading your street machine for ultimate reliability, unsprung and upper-chassis weight is the enemy of performance. Positioned high up in the engine bay or rear corners, a heavy factory battery negatively impacts your car's center of gravity.
The Braille Intensity Carbon i34RX Lithium-ION Battery. Engineered to drop right into your stock battery tray, this powerhouse delivers a ridiculous weight savings of around 40 pounds compared to a standard lead-acid battery. Tipping the scales at a mere 11.5 pounds, it provides a staggering 1,438 Pulse Cranking Amps (PCA). That gives the i34RX one of the highest performance-to-weight ratios in the industry.
Why Upgrade to Braille Lithium?
Standard lead-acid batteries are heavy, inefficient technology. Brailles Lithium-ION cells deliver a higher, cleaner voltage curve that improves the efficiency of your vehicle's entire electrical system.
Faster, Crisper Starts: Operates at a full volt higher than lead-acid with minimal voltage drop during cranking.
Cleaner Data Logging: Stable voltage means cleaner signals for your engine management (ECU) and track data loggers.
Free Up Horsepower: Charges up to 5 times faster than standard batteries, drastically reducing alternator parasitic drag.
Track-Proven Durability: Lasts 35 times longer in harsh track/heat environments with a less than 1% failure rate.
Zero Self-Discharge: Disconnect the battery via a kill switch, and it can sit for over a year and still retain over 13 volts to fire up the engine.
