Product Description
Upgrade to Lightweight, Heavy-Duty Starting Power
Tired of wrestling with a heavy, sluggish lead-acid battery that struggles to turn your bike over after a few weeks in the garage? The Shorai LFM14A1-BS12 lithium-iron battery is the ultimate high-performance upgrade designed to solve your starting frustrations. This premium powersports lithium battery delivers an impressive 210 Cold Cranking Amps (CCA) while weighing a mere 2.80 lbs. By swapping out your old conventional battery, you instantly shed up to 80 percent of dead weight, significantly improving your bike's handling, acceleration, and balance.
Shorai built this rugged engine-starter to meet the exact demands of modern enthusiasts. Unlike traditional batteries that drop voltage quickly under load, this lithium-iron phosphate design operates at a higher voltage range. It maintains that peak energy during cranking, ensuring your engine fires up much faster. This rapid-start technology means less wear and tear on your starter motor and a cleaner, more reliable ignition every single time you hit the switch.
Zero Maintenance and Maximum Lifespan
One of the biggest headaches for riders is battery degradation during the off-season. Traditional lead-acid models suffer from chemical sulfation when left sitting, leading to a dead battery by springtime. The Shorai LFM lithium-iron battery completely eliminates this issue. It holds its charge for months without losing power and will not sulfate while sitting. It is a true drop-in replacement that includes high-density, adhesive-backed foam sheets to guarantee a snug, insulated fit in your factory battery box.
This versatile, high-energy battery is a perfect match for a wide variety of popular machines on the road. It is a highly sought-after power upgrade commonly installed in nimble sportbikes like the Ducati Hypermotard, adventure-ready explorers like the BMW R1300 GS, and versatile sport mounts like the Honda VFR800. No matter where you ride, you can count on rock-solid cranking performance and an exceptional lifespan. Ditch the heavy lead and give your machine the crisp, reliable starting power it deserves. Order your Shorai upgrade from Battery Mart today and feel the difference on your very next ride.
What's the difference between the "equivalent" and "Actual" amp hour capacity?
The manufacturer includes the "equivalent" (PbEq, "lead equivalent") rating to show a more apples-to-apples comparison between the lithium chemistry and the lead-acid battery that you're likely replacing.
The lead-acid capacity rating itself is based on a complete discharge at a low discharge rate. Under actual cranking conditions they will deliver considerably less than spec capacity. And because lead-acid batteries begin sulfating when only a small percentage of the capacity has been used, and their internal resistance rises as they are discharged, the actual capacity which can be used may be as little as 20% of the mfg. rating. Discharge in excess will not only damage the lead-acid battery, it may not allow proper starting as voltage sags.
For example, the Shorai LFM18 12V series have 6Ah cells internally. But, the cells are capable of 80% discharge without damage while still retaining more cranking power. As such, the usable capacity (or "reserve capacity") of an LFM18 12V battery is very close to 18Ah-rated lead acid batteries, while also providing superior cranking and huge weight reductions.
Cold Weather Performance Expectations
Down to about 20° Fahrenheit (-7°C) most users find that they can start normally on first crank. If your headlight comes on at key-ON, it is good for the batteries to flow some current before cranking in cold weather. The suggested headlight-on time before cranking depends on the temperature. If starting at 40°F/5°C, 30 seconds will help wake the battery and increase cranking performance. If at 0°F/-17°C, leave the lights on for 4~5 minutes before cranking. The result will be a better first crank, and longer battery life. If the engine fails to start on first crank, that first crank has warmed the battery, and the second attempt will be much stronger. Other accessories that can be turned on before cranking can also be used for this purpose, such as heated gear, radio, etc... Insuring that the battery is fully charged after storage also improves first-start performance in cold weather.

Frequently Asked Questions
Is the LFM14A1-BS12 the same as the old LFX14A1-BS12?
A: Yes, the LFM14A1-BS12 is the direct, updated manufacturer replacement for the now-discontinued LFX14A1-BS12 model. It features the exact same dimensions (5.83 inches long, 2.63 inches wide, and 4.13 inches high), identical "A" polarity layout, and the same dependable 210 CCA output. The primary update is an improved internal Battery Management System (BMS) for better cell balancing and longevity.
Can I use my standard lead-acid battery charger with this battery?
A: You can use a standard lead-acid charger or maintainer, provided it does not have an automatic "desulfation", "repair", or "recondition" mode. Those high-voltage pulse cycles will permanently damage the lithium cells. For the best performance, safety, and diagnostics, we strongly recommend using the Battery Tender Jr. 12V 800mA charger.
What are the charging system requirements for my vehicle?
A: Your powersports vehicle must have a healthy charging system. At an idle, the system output needs to be at least 13.1 Volts, and it must never exceed 15.2 Volts at maximum engine output. If your vintage or custom bike has a faulty voltage regulator, it must be repaired before installing a lithium battery.
How do I use the included foam padding during installation?
A: Because this lithium battery is significantly smaller and lighter than your original factory lead-acid battery, Shorai includes a variety of high-density, adhesive-backed foam sheets. Simply trim these sheets with scissors and stick them to the bottom or sides of your vehicle's battery box to create a snug, vibration-resistant fit.

Customer Reviews
Super quality and great selection of foam for compartment sizing, I have multiple Shorai batteries in various bikes and have found them to be of superior quality to the competition
Great fit for my bike! Great product and fast shipping!
This is my second Shorai battery. The first one lasted eleven years! Well worth the money. Super light weight also.
I bought this battery to replace one that I unrecoverably drained. It works great. It's even smaller than the one I had, and it came at a good price.
The battery came with everything needed to install it with cleaver packaging. Since the Li battery is smaller than stock, the packaging came with various thickness foam pads with adhesive backing. This foam was used as packaging to protect the battery and then was re-used to perfectly fit the battery in the stock location. Very smart and well thought out.
The battery is very light 1/6th of the
I am using this battery on my 2011 Honda Silverwing. I need a battery that I can trust to get me from Portland, OR to Denver, CO.
This battery is super light, a really strong cranking power. I had to mount the battery upside down since the terminals are in the opposite side of factory battery. No worries it's a gel battery. I'm really pleased with this product it definite was a great price, I search the web and couldn't find a better price. I'm happy and my bike really cranks up.
