Product InformationStore Part Number: LFX27L3-BS12



The Lithium Iron Phosphate battery is the ultimate in weight versus power technology. This battery weighs in at only 4.19 pounds and offers an incredible 405 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 the superior starting power offered in the upgraded versions. Should you not require the most powerful version, see the LFX24L3-BS12 for the less potent lithium alternative for this battery. It will be the exact same dimensions and terminal location as our recommended battery, but with a bit less capacity.

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).


  • No more dead batteries. Holds charge for one year without maintenance
  • Ultra light. One fifth the weight of lead-acid batteries on average
  • Twice to four times the service life of lead-acid batteries
  • Drop-in replacement for your OEM battery
  • Military spec Carbon Fiber Composite Case
  • Faster cranking for better starts
  • Super-fast recharge rate
  • No explosive gasses during charge, no lead, no acid
  • Environmentally friendly
  • Japanese engineering and components


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 27 AH PbEq Lithium Iron Phosphate battery will perform the same as a 27 amp hour Lead-acid battery.

Could Be
Pros: Ready when I want to go riding and long life. That is the whole idea. When I had a problem, off key drain, the assistance was right on and on time.
Cons: Off key drain is the problem. If there isn't off key drain it is wonderful. But they asked me to upgrade to 36 AH for $75 but threw in a charger. Things are looking up.
I am hoping for many years of riding when I want to. I am sharing this with other riders in my area who want to ride on the nice days.

New lite battery in my VROD
Pros: Perfect fit, snug, so very light I'm very satisfied and tell everyone about my new light battery. Its 3 LBs and has twice the cold cranking amps. I don't use the battery tender and so far its holding the charge as advertised. Battery was delivered in 3 days very well packed.
Cons: At $250.00 I think its over priced. If it holds the charge and never dies I'll be satisfied.
