Why You Should Switch to a Shorai Lithium Battery

Shorai Battery

There has been a lot of hub bub about lithium batteries over the past few years.  They are slowly replacing other forms of batteries in everything from smart phones to cars and now even in motorcycles, ATV’s and other forms of powersports.  You can see huge benefits not only for competitive reasons, but for general maintenance as well.

Lithium Motorcycle BatteryLithium batteries do usually require a little more cash out of your pocket upfront, but they definitely pay off in the long run.  One company that has been proving this over the last few years is Shorai.  They are changing the game with their LFX lithium battery and riders are reaping the benefits. So why should you ditch your lead-acid battery and shell out for a new Shorai lithium motorcycle battery?  Here’s what you need to know.

For anyone who wants to gain an edge over their competitors, shedding extra weight has to be a top priority.  Traditional lead-acid batteries can really weigh your machine down.  By switching to the Shorai LFX, you can dramatically shave the weight off of your bike or ATV.  In fact, the LFX will be up to 80% lighter than your stock lead-acid battery.  Shorai claims that their LFX battery will cut an average of 2-3 pounds for dirt bikes, 6-8 pounds for street bikes and an extraordinary 10-20 pounds for cruisers and touring bikes.  You’ll be hard-pressed to find an easier way to shed that much weight on your bike.

Does the smaller size and weight of lithium batteries mean that you will lose cranking power with them?  The answer is actually quite the opposite.  Despite being smaller, the Shorai battery, along with most other lithium motorcycle batteries, actually make your starter crank faster than lead-acid batteries because they operate at a higher voltage range.  Faster cranking means that your bike has a better chance of starting and is easier on your starter with the extra oompf.

All of that is awesome, but if you are someone who really doesn’t care about the added performance, the added convenience might be what convinces you to switch.

After long rides, it’s easy to forget to hook up your Battery Tender on your bike.  When that happens, you’re left with a dead battery the next time you go to ride.  If you continue to drain the battery down, it can degrade over time.  The LFX has a very low self-discharge rate that allows it to hold a charge for a very long time.  A rider could leave their fully charged LFX battery unattended for at least 6 months and possibly even a year and the bike will still start.

Also, you don’t have to worry about sulfation with lithium batteries like the Shorai LFX.  Sulfation is the formation of large crystalline deposits on the negative plates.  This reduces the high capacity and low resistance active material in the battery making it less effective and it will take much longer to fully charge.  If sulfation is allowed to continue, it can become irreversible and your battery will eventually become worthless.

Another benefit of lithium batteries is that you are not dealing with explosive gasses, lead or acid.  The LFX is a sealed battery and is far easier to work with compared to a lead-acid battery.

Even though the lithium batteries are sealed, you still don’t want them bouncing around in your battery box, which they will be prone to do since they are much smaller.  Shorai has you covered, though.  With their LFX battery, they provide you with enough foam to shim around your battery to make it very stable.

In the rare times that you need to charge your lithium battery, it is recommended that you use a charger made specifically for lithium batteries.  You will still be able to use your standard charger in a pinch, though.

If you’re looking to shave weight, gain performance and almost completely forget about battery maintenance, you need to check out the Shorai LFX batteries for your bike.

      Shorai makes a charger that is specifically made for these batteries, however, any battery charger will work to recharge the battery, though probably not as well as their charger. Here is their charger.

    What about longevity? Will it last longer?

      You can expect that a Shorai Lithium battery will have at least twice as long of a lifespan than a lead-acid battery, if not longer.
