>>HP Autowerks<< Light weight Braille racing battery custom mounting kit

Enjoy up to 40lb weight reduction over the BMW OEM battery by using the HP Autowerks lightweight aluminum battery tray and Braille lightweight racing battery. Yes, you don't need to spend $6K on an Akrapovic exhaust for the same weight savings! Plus the battery mounts above and away from the center of gravity of the vehicle making it even more important to take weight away at those locations. The tray accomodates three different Braille battery sizes. Please choose which battery you would like inlcuded with your HPA battery tray from the options below.

Mounting tray is $85 when purchased with a Braille lightweight racing battery.

Fiberglass reinforced plastic (FRP)

All Braille batteries feature an industry leading energy-to-weight ratio accomplished via Enhanced Mat Technology (for more surface area on the lead plates) combined with calcium full frame power path grids (for increased cranking power).

Durability is also built into every Braille battery. Using high-density oxide, Braille batteries offer true deep-cycling ability over the life of the battery. Heavy-duty vibration resistant power posts resist cracking and deterioration common to many lightweight batteries used in harsh automotive environments. The battery is a sealed unit that can be mounted in any position safely using its adjustable automotive terminal posts.

Braille batteries include a one-year free replacement limited warranty that is not pro-rated.


This same battery is installed in the Berk Technology's Redline Time Attack Race Car, our Red Line Time Attack 335i and our project 135i and 1M.

Note: We recommend a minimum of 21 lb battery for E8x 1-series. Some vehicles may require "Battery Replacment Registration" for the charging system to properly charge the battery.

Do these light weight batteries last as long as OEM (regular) batteries?

In short, is there any catch to switching my 135 (or even 325) to this lightweight battery? Any negatives?

Generally reduced capacity and CCA. If you have any parasitic loss it can strand you very quickly.

There is a reason why BMW uses such a large battery in the 1 and 3 series, for reserve capacity and cold cranking amps. With a smaller battery you will see both of those reduced. However, if you are careful not to run your electrical consumers for hours and don't do a bunch of short 1-2 mile trips, the 21 lb. battery is very good for daily use.

I have done a personal test on a 2011 135i by letting the radio run for a couple of hours, no issues there. Park the car for over 2 weeks, it started right up.
