Shorai's Lithium Iron batteries are the ultimate fusion of light weight and power technologies. The LFX14A5-BS12 battery weighs in at 2.27 pounds and offers 210 CCA. These batteries will require no change to your charging systems and are a drop-in replacement for your original battery (Included shims may be required for installation).
What makes Shorai batteries different? They contain Shorai-proprietary eXtreme-Rate Lithium Iron prismatic cells (chemistry LiFEPO4). They contain no poisonous lead, no dangerous acid, and do not create explosive gases during charge, as traditional Lead-Acid batteries do. Compared to traditional batteries, Shorai lithium batteries are extremely light, have much lower self-discharge rate, do not sulfate, and are environmentally friendly.
Can I use Lead-Acid battery chargers or charger/tenders?
Yes. HOWEVER, you may NOT use a charger/tender if it has an automatic desulfation mode, which cannot be turned off. We have 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 batteries.
Can Shorai LFX be mounted in any position?
Yes. There are no liquids in these batteries.
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 LFX18 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 LFX18 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.
I put this battery into a 1982 Honda CB650. It's a drop in replacement, no fuss no muss. It's easily 6 pounds lighter than the old lead acid battery. It also works well with the crappy old charging system on this last of the SOHC 4's from Honda. What I am liking most about it, is that there is no maintenance. No trying to pour 1/2 oz of distilled water into each of six cells on the old lead acid. Holds a charge for what seems like forever. I ride this old bike about once a week and that's more than enough to keep it charged. Cranks strong and longer than the old lead acid. It's a little odd getting used to "waking up" the battery in really cold temps - 40'ish or below, but the Shorai has no problems cranking over the bike at these lower temperatures. This is also a Lithium IRON battery, not Lithium ION, so there isn't that crazy risk of explosion due to thermal runaway. For you café racer folks, being completely closed, you cam mount it in any orientation you want. Do yourself a favor, drop the extra coin on one of these, you'll be glad you did.
Charges fully much faster than lead acid battery. Seems to have more available surge/starting power. Exact fit for the motorcycle battery box.
Fit existing battery case on motorcycle perfectly
off road racing the size is great all the pads inclluded made the fit perfect
