Shorai's Lithium Iron batteries are the ultimate fusion of light weight and power technologies. The LFX21A6-BS12 battery weighs in at 3.03 pounds and offers 315 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.
Just purchased this battery but seems to work as described.
This is my second Shorai battery, the first one is still in one of my bikes, that's why I bought another one... they work great, they are light and have a long shelf and working life.
I have recently purchased one Shorai from Battery Mart. Easy to order, best price, and shipping was FAST. After seeing the performance of the battery and the fantastic service that was provided by Battery Mart I ordered two additional Shorai's for our ATVs. They weigh a fourth what traditional batteries weigh and the additional amps and performance are amazing. Thanks to Battery Mart I made the right decision versus the other options.
The day my new battery arrived it was thrown over the fence and 20 feet into my front yard by the Fed Ex driver. I went to meet him just as he did it. If this battery had been acid filled, it would have been ruined. And the box that Shorai provides to ship there batteries is so well protected and designed, it could take a 50 foot drop on concrete I bet. I dropped it into my 2012 Kawasaki Concours that the stock battery finally gave up in, and it started right up.
I didnt charge it just put it in the bike. It sat a week because its too cold to ride and after a week of sub 40 degree weather it started right up again! Nuff said...
Delivery was prompt. Price was good.
The battery is great
Installed in my Honda ST1100. The battery is powerful with great cranking amps. Even when it sits for a couple of weeks, my amp meter still indicates a full charge.
I had to modify the Honda battery connectors when I installed the battery. That simply required a little reshaping of the metal connector. Works fine and is performing admirably. The real proof will be in the age durability a coup
