The Lithium Iron Phosphate battery is the ultimate in weight versus power technology. This battery weighs in at only 1.01 pounds and offers an incredible 102 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. For this reason has chosen to only carry the more powerful version of this battery, see the LFX14L2-BS12. It will be the exact same dimensions and terminal location as Shorai recommended battery, but with a bit more 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 9 AH PbEq Lithium Iron Phosphate battery will perform the same as a 9 amp hour Lead-acid battery.

Puny but Powerful
Pros: Fits in a Chinese scooter (gy6 150cc) with the shims provided. (Easy installation) Starts engine better than old AGM battery. (Faster starts) Takes a charge surprisingly quick. Spend less time worrying about how to get home.
Cons: Costs about 3 times as much as original AGM battery. Unknown real world life expectancy (but hopefully 5 yrs) Electronics instructor made fun of its size! If overdischarged, battery life will be compromised.
If nobody ever tried anything new or different, technology could not advance. So I made up my mind to try something new.
The scooter cranked up like an excited bumblebee as soon as I touched the starter. This battery will be cared for- that's for sure. That means never forgetting turning out the lights . duh

Shorai Lithium 9 AH 12V Battery for my Classic Triumph
Pros: I decided to try a lithium battery and was recommended to me by a riding friend. I went on the website, checked with Jeremy, who was very helpful, and decided to go ahead with the purchase since the price wa right and the shippping was free. I ordered it at noon on Monday and the USPS delivered it to Massachusetts with my regular mail on Wednesday!!!!!!!! I installed it in my motorcycle on Friday. It was as advertised and has performed up to my high expectations. The only question left to be answered is its longevity and that will have to wait a few years. That's the only reason I didn't give a five star rating.
Cons: You should have classic Triumphs on your motorcycle list.
