Why Choose The #1 Selling Lithium Battery in the U.S.A?
The Shorai LFX Lithium motorcycle batteries are some of the lightest and most powerful replacement batteries available! SHORAI LFX Lithium-Iron Powersports battery, 12Ah PbEq 12V eq, "A" polarity, Case Type 1
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.

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 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
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.
