The Lithium Iron Phosphate battery is the ultimate in weight versus power technology. This battery weighs in at only 1.99 pounds and offers an incredible 210 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.

This is the heavy duty LFX14A4-BS12 battery. It offers an incredible 210 C.C.A., and the Lead-Acid Equivalent of 14 amp hours. It weighs in at only 1.99 pounds and yet still has the power to spin over even the most stubborn engines. Not only does this battery offer incredible advantaged over the lead-acid battery in weight, but also in physical size. This battery will effectively take the place of a YTZ10S in power, but it is not larger than a YTX12 battery.

We recommend using this battery in your regular commuters, your frequent play vehicles, and anything that may require that extra punch to start.

*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.

Not Fully Developed
Pros: Sure its light and small.
Cons: This battery is simply LiFePO4 battery without a battery management system to ensure the battery is evenly charged to all cells. Also, the battery can be damaged from higher charge rates (such as high revving) or a drop in power consumption due to leaving your lights on for a short period. The effects by these two issues are not as repairable as other batteries can handle. Without a BMS and/or regulator to keep the battery safe in the even of charger system issues or leaving your lights on will damage the battery beyond repair.
Buyer beware.

**NOTE From BatteryStuff** Shorai batteries are not designed for supplying power for lights or other long term electronics. The same is true for any starting battery, not just lithium. They are also designed to be re-charged just like any other lead acid equivalent. If the battery is being overcharged, there may be something wrong with the stater on the bike. In order to balance the cells properly, please use the Shorai Sho-BMS01 LiFePO4 charger. If a Shorai battery is discharged, there is no damaging sulfation effect. Simply bringing the battery back to full charge should not leave the battery with any non-repairable issues.

shorai lithium LiFeP04
Pros: Started my bike on first ignition turn on which no other battery could do in 8 years and 4 batteries later. Impressive starting power for size and weight.
Cons: Non yet will try to start again after sitting for 3 weeks.

FOR REAL Best Motorcycle Battery Ever
Pros: PROS I never write product reviews and much less about a vehicle battery, but I have to give it to Shorai:
Cons: They don't make batteries for cars :-( They did not come into the market until recently, "Where were you when I needed you!" :-( I haven't push-started a motorcycle since I first saw the Shorai logo!!
Customer service is awesome!!
I have three bikes and by now they all have Shorais on board.
My Superhawk had an old R&R unit and loss charge frequently until Shorai, gave me a new higher charge replacement battery at no charge and helped me solve the issue permanently with a smile.

Quite a resilient battery
Pros: Very light weight, can be charged via most standard battery chargers, lots of power, wasy to intstall, comes with padding
Cons: It is a bit expensive...but if it never goes, it's not much of a con.
I had went online and watched the videos for these types of batteries and how well they work at different temperatures. I was able to start mine when the engine had been sitting and cold around 45 degrees with only about 3 cranks!

light weight
Pros: Battery is light; I thought it couldn't be real. Starts my Honda 919 great. Very quick starts.
Cons: Have only had it for a couple weeks and it seems great. We'll see how it lasts, but I'm expecting good things.

Simply the best
Pros: Wow, hands down the best battery I have every seen for a motorcycle. Powerful starts in my 2012 GSXR 750. I would compare this in power and quality to the Optima line I use in my 2500 Truck and 1968 SS Camaro. It weighs nothing and was a perfect fit after I put the foam that came with it under the battery as it is a little shorter then OEM but who cares right? I have been running it for over a month now and I am as happy as can be. Sure it costs more but the finer things in life usually do! It's nice to have a battery in my bike that I know is going to be ready to go on a moments notice even if it sits for a week or a month without use. Why to go Shorai!
Cons: I have not found one yet..
For any very long unused periods I would store it in the refrigerator, cooler is better!

Very powerful
Pros: Easy to install into my Kawasaki ZX-6. It has no liquid to fill. The foam pads that come with the box are a great way to fill out the bottom and sides since this battery is quite smaller than the original size. What a joy to start the bike now. My previous battery was on a trickle charger and after parking the bike twice the battery was too weak to start the bike. I got good exercises running the bike on.
Cons: None so far.
