Due to extremely high demand and large orders of our lithium batteries, production lead time is 2-3 business days.  We are expanding our production capabilities and will get products out as fast as possible.   Thank you for your understanding. 


Braille I34S (left positive) is the high power & capacity lithium upgrade in a common Group 34 size.  

- Max weight Savings (often replaces a PAIR of lead batteries at 40-50 lbs each)

- 100% compatible with ALL standard charging systems

- Can be used in total loss (no alternator) applications

- True "Race Grade" lithium battery Made in USA (Sarasota, Florida)

- Most reliable lithium battery on the market 

- Over a decade of use in street & race vehicles & used by more professional race teams, car builders and race series globally than any other lithium battery on the market!! 


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 1-2 business days (same or next day if in stock) depending on model, time of year, order volume and various factors.
