Our LFX Standard recommendation is the best overall pick for most applications, and has been selected to give strong cranking performance and long lifespan. This LFX battery is 7.88 Lbs. lighter than the Yuasa lead-acid 51913L.
Shorai LFX batteries contain Shorai-proprietary eXtreme-Rate Lithium Iron prismatic cells (chemistry LiFePO4). Shorai LFX contain no poisonous lead, no dangerous acid, and do not create explosive gasses during charge, as traditional Lead-Acid batteries do. Compared to lead-acid, Shorai LFX lithium are also extremely light, have much lower self-discharge rate, do not sulfate (i.e. do not degrade while sitting unattended), and are environmentally friendly.
While there are other companies now offering Lithium-Iron based powersports batteries, all except Shorai use cylindrical cells originally made for power tool applications. Such cells are inferior to Shorai Prismatic LFX.

Important notes: Your motorcycle charging system must produce 13.6-14.4 volts at 2000 RPM. DO 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 LFX, for example. But the best possible charger/tender for Shorai LFX is the SHO-BMS01. 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, 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. If you do choose to use a "smart" charger that you've confirmed does not have a desulfation mode on your Shorai, please disconnect and reconnect periodically (once every 7-10 days).
