Extreme Power Series (XPS) Small Case Lithium Battery

Though a minuscule 4.375″ Length x 1.37″ Depth and 3.75″ Height (to the top of the terminals) the SC1 battery can start a V8 Motor! It weighs less than 1 lb, yet is as powerful as our competitors’ batteries that are TWICE the size. For example if you used an 8-Cell Ballistic battery before, our SC-1 can start anything the 8-Cell Ballistic does and is HALF the weight and HALF the size!

NOT RECOMMENDED FOR DAILY DRIVER TYPE VEHICLES!!!! It has a smaller capacity than recommended for regular use in street-only vehicles. USE for RACE.

    Installed this battery in a KLX110L solely for more cranking power and a lighter weight and it has performed flawlessly ever since!

  2. KWICK Aronson

    Well, it’s been 25 months as my SC-1, used in street riding, finally started getting weak. Again, 25 months of street usage!! Pretty incredible for a battery that weighs under a pound! This is on my ZRX1100 with an 1109 big bore kit and 12.5:1 compression. As I have said many times, I’d be extremely happy if it only lasted 6-8 months…but 25?? WOW!!!! I will run this battery forever!

    Installed 12/12/2013, see my previous review, still starting my Kawasaki ZRX1109. Cold mornings take a couple-three cycles to get the battery to spin fast, but it always starts.
