B3121C - Carbon Lightweight AGM battery
$341.24
At 21 pounds, the B3121 is our lightest do eveything battery yet. Using our Advanced AGM racing technology we have put a lot of power into a very small package. With 1380 pulse cranking amps this has enough power to start more than any other battery in its weight class. This is the perfect model for those who want to shave half the weight of a standard Group 34 battery and still have enough power to crank over a steet car with V8 engine & standard compression. Used in everything from large Harley Davidsons to Hot Rods, road race cars, Corvettes & Vipers. (Note: while high in cranking amps, make sure battery has enough capacity for the vehicle intended to be used in.  Not designed for big block, high compression motors, those with no alternator, etc. where a full-size battery with high capacity is required.) 
Description

Higher engine temps equal lower battery performance. Braille's exclusive Carbon Fiber Case protects the batteries internals from high temps and provides the longest service life. Don't settle for a metal case that conducts heat, be cool.

Note: Carbon case is slightly wider & longer than standard case, so battery boxes with tight tolerances may require some modifications. Measure to ensure fitment.
