Product InformationStore Part Number: LFX19A4-BS12


The Lithium Iron Phosphate battery is the ultimate in weight versus power technology. This battery weighs in at only 2.31 pounds and offers an incredible 285 C.C.A. This is a drop in replacement for your Lead-acid battery, and will require no change to your stock charging system.

Shorai LFX batteries contain Shorai-proprietary eXtreme-Rate Lithium Iron prismatic cells (chemistry LiFePO4). They contain no poisonous lead, no acid, and do not create gasses during charge, as traditional Lead-Acid batteries do. Compared to lead-acid, Lithium Iron Phosphate batteries are also extremely light, have much lower self-discharge, do not sulfate, and are environmentally friendly.

When it comes to Powersports applications and lithium batteries, recommends that you use the best, most powerful version that will properly fit your application. Shorai may list several battery sizes in their application chart that will fit your bike, but in our opinion the small gains in weight are typically offset by she superior starting power offered in the upgraded versions.

Lead acid batteries have long been a target with riders who want to take weight off of their motorcycle. With our Lithium Iron Phosphate batteries, it is now possible to do away with the heavier lead acid battery, while maintaining reliable starting power. These are true drop in replacement batteries that will require no charging system modifications, and only weigh a fraction of the OEM battery.

*BatteryStuff understands the importance of getting a replacement battery right away and usually ships all batteries the same day as ordered if received before 1:30pm (Pacific), however USPS does not guarantee delivery times with priority mail.


  • No more dead batteries. Holds charge for one year without maintenance
  • Ultra light. One fifth the weight of lead-acid batteries on average

We recommend using these batteries in temperatures above 0 degrees Celsius. This battery may require spacers to make it work in your application. Included with this battery are foam spacers that will aid in fitting this battery. ** PbEq equals Lead-Acid Equivalent. This means that a 12 AH PbEq Lithium Iron Phosphate battery will perform the same as a 12 amp hour Lead-acid battery.
