Shorai LFX Lithium Iron Battery LFX19A4-BS12

Shorai LFX Lithium motorcycle batteries are some of the lightest and most powerful replacement batteries available. Most powersports enthusiasts have gotten used to hooking up a tender to their lead-acid batteries, all the time. Shorai LFX have a much slower self-discharge than the best lead acid batteries (1/6 to 1/7, on average), they do not sulfate as capacity drops, and they are the ultimate "deep cycle" battery. This means that they can still crank your vehicle even if the remaining capacity is quite low. A fully charged LFX can sit for a year or more and still retain adequate starting capacity, without damaging the battery. As such, any vehicle which has no current flowing when the key is OFF should not need a tender. At most this battery only needs to be charged every 6 to 12 months, depending on the use and average storage temperature. Newer vehicles may have a significant draw even when the key is OFF, to maintain clocks and computers, etc. In this case Shorai expects that a few hours of riding per month will be all that is needed to avoid tending. If you know that you will go a number of weeks or months without riding, you can either attach a tender, or disconnect the negative cable from the battery. In any case, during storage you may use the voltage chart above and an accurate voltmeter, and consider recharging when the battery is around the 50% capacity remaining mark, or above.

  • Faster cranking for better starts
  • Ultra light- one fifth the weight of lead-acid batteries on average

Notes:

  • All Shorai Batteries require charging out of the box prior to use.
  • It is extremely important that you use only the appropriate battery for your bike. A battery with incorrect amperage may damage the battery and your bike.
  • Shorai Batteries require a charging system output of 13.1 Volts or higher at idle and must not exceed 15.2 volts at maximum output.
  • Shorai Batteries may not be a drop in replacement for all bikes, some modification to battery box, terminals etc may be necessary.
  • Shorai recommends NOT using a charger or tender if it has a desulfation mode which cannot be turned off. Shorai has confirmed that the Battery Tender brand does NOT have a desulfation mode and are OK for use with Shorai LFX batteries. However the best possible charger/tender for the Shorai LFX is the Shorai SHO-BMS01 Battery Management System.

Light and compact, but comes at a price.
after my old battery quit on me, I decided to spend the extra cash and get one of these to see what the hype was all about. I was amazed at how light the box was and even more surprised to open and see that most of what was inside was foam. These batteries are shipped with a lot of different size foam padding for you to fill the empty area of your battery box after installation. I didn't need any foam since I was doing a tail conversion and new battery box was pretty small already. I completed all the work and cranked the beast and the extra cranking power of this battery was very noticeable. After a week, i parked the bike and could not ride for 2 weeks. I then, had some time off and got all geared up to go for a ride, but bike was dead! Not even a needle twitching, nothing! I started doing troubleshooting and when check voltage at the terminals, it read 2 volts. I gave revzilla a call and their great customer service rep. Explained that shorai likes to deal with their warranty issues directly and provided me with the contact info. I called shorai and a nice female quickly offered help and asked some help about my bike's electrical setup and gadgets. The minute I mentioned that all I had was an alarm system, she explained to me that, even thought these batteries have more cranking amps, they can't hold that charge as long as a "regular" battery and said I needed the fancy charger to maintain it or disconnected from the bike. I was also given the option to ship the battery for them to try to recharge it or get a replacement. I decided on the replacement and she kindly offered a nice discount on the special charger for it too. I received my new battery and sent the old one back and haven't had any issues after that, but I never let the bike sit more than 2 days off the charger. Maybe I can go a lot longer, but I'm afraid to test that again.
So, I would still recommend this battery, but be ready to spend the extra money on the charger unless, you ride very often.

Only way to go!
I've had this battery over three years and it's still running like brand new. Several times throughout the years I have let the battery drain completely from several weeks of non-use..only to completely recharge to full compacity within a few hours using Shorai's battery charger. I bought the heavier duty battery because I have a 2-way alarm, air horn, extra lights and usb outlets for phone and bluetooth on my K8 GSXR 1000. This battery will last over 7 weeks if I don't start it at all and with the alarm activated! Definitely get Shorai's charger with the battery. Very light and easy to install. This will be the last battery you'll ever buy for your bike. Definitely will recommend to fellow bikers.

In your hand you won't believe the difference in weight from your old battery. Fires strong every time without a hint of effort. Cheapest way to shed pounds off a bike.

LFX19A4 vs LFX14A4
4 years ago Shorai recommended the LFX14A4 for my 2007 Kawa Z1000 but now they recommend the LFX19A4
What changed and would the LFX19A4 really be a better fit with 75 more cranking amps? (285 vs 210)
Stefaan V on May 9, 2017
BEST ANSWER: I went with the newest recommended version, of course I had to use the included foam and rotate the battery for the pos. And neg. terminals to fit but it's snug and cranks very well. Happy so far.
