Shorai LFX Lithium Battery

The Shorai LFX Lithium motorcycle batteries are some of the lightest and most powerful replacement batteries available!

See Shorai Specifications and Dimensions data sheet (pdf) for fitment guide and specifications.

Most powersports enthusiasts have gotten used to hooking up a tender to their lead-acid batteries, all the time. Shorai LFX have much slower self-discharge than the best lead acid do (1/6 to 1/7, on average), they do not sulfate as capacity drops, and they are the ultimate "deep cycle" battery, which means that they can still crank your vehicle even if the remaining capacity is quite low. Therefore most riders will not need to use a tender at all. 

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 never need a tender. At most it should be charged every 6 to 12 months, depending on the average storage temperature (cool storage is much better for any battery).

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.

Features:

  • Ultra light - one fifth the weight of lead-acid batteries on average
  • Zero sulfation for longer service life
  • Holds unloaded charge for one year without maintenance
  • Military spec Carbon Composite Case
  • Faster cranking for better starts
  • Super-fast recharge rate
  • No explosive gasses during charge, no lead, no acid
  • Environmentally friendly
  • Two-Year Warranty!

Shorai recommends NOT using a charger/tender if it has an automatic "desulfation mode," which cannot be turned off. Shorai has confirmed with Deltran, makers of the "Battery Tender" brand, that their products do NOT have a desulfation mode, and are therefore OK for use with Shorai LFX. However the best possible charger/tender for Shorai LFX is the Shorai SHO-BMS01 Battery Management System.

  • Case Size 1: 148mm length
  • Case Size 2: 113mm length
  • Case Size 3: 166mm length
  • Case Size 4: 148mm length
  • Case Size 5: 134mm length
  • Case Size 6: 148mm length 

See Shorai Specifications and Dimensions data sheet (pdf) for fitment guide and specifications.

Please Note: It is extremely important that you use only the appropriate battery for your bike! A battery with incorrect amperage may damage the battery or worse yet, your ride. 

Shorai Batteries may not be a drop in replacement, some modification to battery box, terminals etc may be necessary.

Shorai Lithium Battery LFX18A1-BS12 4.6 5 134 134
a positive revolution in battery technology this was my third purchase of a shorei battery. one for a BMW m/c and two for small airplane. i replaced one of these because i accidentally left it drawing current for three weeks. of course it was dead and i believed it would not come back to life but put "dead" unit on battery tender junior just for kicks. it came back to life. no downsides except for small cost premium. super light and small. no tender needed: stays at about 13.4 volts after months of non-use. beautifully made. easy to install. great customer service. (one order arrived next day altho i paid for ground.) always fully charged when arrives. January 19, 2016
Next Generation Battery My DR650 came to life this morning in 20F weather. Cranked like it was 95F out. I love the weight of this battery, about 400% lighter than my previous battery. They are expensive, true story. If you can afford one, buy one, maintain it properly, and it should keep you smiling. January 5, 2016
Great batteries I have a Shorai battery for over 3 years now, with the dedicated charger. I ride almost in all weather conditions. This battery never failed me so far (gotta remember maintenance, just like with every other). Yesterday 4.01.2016 the bike was standing in -15'C for 9 hrs, I had to crank it a few times before it started (it was very cold), and add a little throttle. But the battery did its job. Now I'll have to wait until its warmer, like -5'C to start riding again. Its not a pleasant ride it such a low temperature. It's an expensive battery but You get what You pay for. I totally recommend Shorai batteries. January 5, 2016
next day delivery Battery is working just fine, no surprise. Got what I ordered and it fits. Couldn't believe I ordered one day, received it the next day, and I don't recall even paying for shipping. Great company and great service. January 27, 2016
Shorai Rocks! Love Shorai and there customer service is excellent. Do not buy another battery. January 19, 2016
Good in warm weather, poor otherwise This battery kept me happy for about a year, but now with a colder than usual winter here (Northern California) it's showing its ugly side. My bike sits outside, and is ridden usually once a week, weather allowing. I always disconnect the battery when not riding so there's no parasitic draw on it. Starting my bike in cold (less than 45F or so) weather is almost impossible with this battery, it's very very weak. Lately with temperatures in the low thirties it's been impossible. Warming it up by having the lights on as Shorai recommends doesn't really help, it requires 4 or 5 start attempts to wake up the battery, and by then there's a high chance the spark plugs have been flooded from all the cranking with no start. Not very healthy on the starting system either to try to start with such a weak battery. For a product of this price, I find it hard to recommend unless you always have warm climate or have a heated garage. December 27, 2015
Super Light and Extremely Easy to Install Bought after my stock Yuasa AGM died after 4 years. Extremely easy to install and saving 8lbs over the stock battery was a nice added value. My only gripe would be the charging port location...it sits right under the tie down strap. Super fast shipping from Revzilla! You guys always deliver! November 10, 2015
Perfect for the winter Much quicker starts even in the cold! It's mid December and I haven't started the bike in 3 months. One touch and VROOM! Ready to go. December 14, 2015
