Available on backorder


Shorai Lithium 12 Volt Battery

PLEASE NOTE: This battery must be used with an electronic regulator or a new Cycle Electric Generator. IT WILL NOT WORK WITH AN ORIGINAL CHARGING SYSTEM! The original stock mechanical Cutouts and Regulators will overcharge the battery within 30 miles and cause it to catch fire. If you have upgraded your motorcycle to the new Cycle Electric Generator this battery will work perfectly. 

This battery, unlike the typical lead acid battery, is physically the smallest 12v battery, but it has the largest amp hour rating of any battery we offer! This Lithium Ion technology is amazing!

This is a newly designed exclusively for motorcycles, Lithium Ion battery extended capacity 21amp hour

Dimensions: 5.83 x 3.23″ x 5.51″ Height (all dimensions are approximate)

NEW Shorai 12V Lithium Ion Battery – 21amp/hr
Compared to Lead acid batteries:

  • The Ultimate battery – Place it in the shell and forget about it! No Maintenance
  • Much Lower self-discharge rate ( do not sulfate) – Can last for over 12 months without becoming discharged!
  • Longer Life: We expect Shorai batteries to last 5 to 6 years and under ideal storage conditions we expect 8-10 years to be achievable. Due to their lack of sulfation and slow-self discharge, Shorai LFX increase battery life most for users who sometimes store their vehicles for weeks or months at a time, and don’t want to or can’t use a battery tender.
  • Never need to check water levels since there is no acid to sulfate away!
  • Will not harm your expensive antique motorcycle with acid sulfation. Completely clean!
  • Better for your antique motorcycle than other AGM/sealed/Maintenance-free batteries, because they still have acid that can cause problems.
  • Ultra light.� One Fifth the weight of lead-acid batteries on average
  • Zero sulfation, for longer service life
  • Holds unloaded charge for one year without maintenance
  • Military spec Carbon Composite Case
  • Faster cranking for better starts
  • Super-fast recharge rate
  • No explosive gasses during charge, no lead, no acid
  • Environmentally friendly Two-Year Warranty!
  • Total Lifespan cost of battery is lower than lead acid batteries
