Shorai Lithium Battery LFX21A6-BS12 Resources

Shorai LFX Lithium Iron Battery LFX21A6-BS12

Shorai LFX Lithium motorcycle batteries are some of the lightest and most powerful replacement batteries available. Most motorcycle owners are used to hooking up a tender to their lead-acid batteries, all the time. Shorai LFX have a much slower self-discharge than the best lead acid batteries. This means that they can still crank your vehicle even if the remaining capacity is low. 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 not need a tender. 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. At most this battery only needs to be charged once or twice a year, depending on the use and average storage temperature.

Features:

  • Faster cranking for better starts
  • Ultra light- one fifth the weight of lead-acid batteries on average
  • Holds unloaded charge for one year without maintenance
  • Zero sulfation for longer service life
  • Super-fast recharge rate
  • No explosive gasses during charge, no lead, no acid
  • Military spec carbon composite case
  • Multiple terminal connection options
  • Includes adhesive back foam sheets
  • Factory activated
  • Environmentally friendly
  • 2 year warranty

Specs:

  • 12 V- Volts
  • 315 CCA- Cold Cranking Amps
  • 21 Ah- Amp Hours
  • 94 Wh- Watt Hours
  • Weight: 3.03 lbs/1.38 kg

  • Case Size 6: 82mm/3.23" x 148mm/5.83" x 140mm/5.51"
  • See Shorai Specs PDF below for full fitment guide

Notes:

  • It is extremely important that you use only the appropriate battery for your bike. A battery with incorrect amperage may damage the battery and your bike.
  • 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 Batteries may not be a drop in replacement for all bikes, some modification to battery box, terminals etc may be necessary.
  • Shorai recommends testing and charging all batteries prior to using.
  • Shorai recommends NOT using a charger or tender if it has a desulfation mode which cannot be turned off. Shorai has confirmed that the Battery Tender brand does NOT have a desulfation mode and are OK for use with Shorai LFX batteries. However the best possible charger/tender for the Shorai LFX is the Shorai SHO-BMS01 Battery Management System.
