Whether you are looking to replace your battery to reduce weight for track purposes or just want to upgrade to a lithium battery for it's long life and exceptional reliability, Braille Battery has you cover with their Intensity line of Lithium-ION batteries. Designed to the same stock specifications in terms of size, for easy installation and proper fitment, these batteries are significantly light that stock batteries by a ridiculous amount! The i34 battery weighs in at only 11.51lbs! This is a ~40 pound reduction in weight, while still producing a whopping 1438 Pulse Cranking Amps (PCA) and offering a 26 Lithium Amp Hour/Lead-Acid Equivalent capacity. This makes the i34RX another leader in the battery industry for performance to weight ratio by a significant margin!

Some may ask, "Why should I upgrade to a Lithium battery?"

Braille Lithium delivers a higher, cleaner voltage which improves the performance of every electrical component and has shown to provide:

  • Quicker starting (a full volt higher than lead and less voltage drop during cranking)
  • Improved engine management & data logging performance (more stable voltage)
  • Less horsepower draw from the alternator due to efficient charging (5 times faster than lead),
  • Lasts 3-5 times longer (especially under the harshest environments),
  • Much more reliable (less than 1% failure rate)
  • Significant weight savings. (up to 1/4 the weight)
  • 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!!

Physical Specifications:

  • BCI Group:  34
  • Weight:  11.5lbs / 5.22kg
  • Length:  10.87" / 276mm
  • Width:  6.9" / 173mm
  • Height:  7.7" / 195mm
  • Polarity:  Right Side Positive

Performance Specifications:

  • Voltage:  12
  • Full Charge Voltage:  13.8
  • Pulse Cranking Amps (PCA):  1438
  • Amp Hour (AH):  26
  • Lithium Amp Hour/Lead-Acid Equivalent (LAH/PbEq):  78
  • Life Cycle @ 10% DOD:  5000

** PbEq equals Lead-Acid Equivalent also known as LAH Lithium-Amp-Hours. This means that a 72 LAH PbEq (24AH) Lithium Iron Phosphate battery could perform the same near as a 72 AH Lead-acid battery under a high rate discharge in comparison.

When installing a lithium battery in a MINI that requires the battery to be coded in, Braille recommends setting the battery code to the lowest/smallest AGM battery setting possible.

Before purchasing a battery, please double check the size of your stock battery and the battery compartment. Many MINI's can use both a Group 34 or Group 35 size, but some vehicles are limited to Group 34 only due to constraints in the battery's total length.
