Ultra lightweight Lithium motorcycle batteries with improved starting performance and zero sulphation for longer life


  • Ultra lightweight design - up to 75% lighter than a lead acid equivalent
  • Zero sulphation for longer service life
  • Faster cranking for improved starting performance
  • Rugged carbon composite casing

Please note, Lithium batteries are far more sensitive to overcharging than conventional lead acid batteries and should not be used with older bikes particularly those with mechanical voltage regulators; they should only be used on newer bikes fitted with sophisticated electronically controlled charging systems - if you unsure please contact us for advice.

LFX14L2-BS12: Storage Capacity 4.4Ah Lead Acid equivalent 14Ah

Lithium/Iron batteries are around three times more efficient than traditional Lead/Acid batteries which means that up to 80% of their storage capacity is available as usable power compared to only 20-30% for a typical Lead battery. This means that a Lithium battery with a much lower capacity can provide the same starting performance so to help compare Lithium and Lead batteries all our Lithium batteries have both "Storage capacity" and "Lead/Acid equivalent capacity" ratings.





The Shorai LFX14L2-BS12 can be used to replace the following battery part numbers

What are the advantages of Lithium batteries?
Lithium batteries offer two significant advantages over conventional lead acid batteries - firstly they are much lighter and secondly they are far more efficient so can deliver far greater cranking power to start your bike. You should be aware however that while they have improved starting performance, they have lower capacity than a lead acid battery and hence are not suitable for applications that require significant battery capacity. 

What type of charger should I use?
You should always use a Lithium optimised charger, such as the Optimate Lithium 0.8 or the CTEK LithiumXS - do not use conventional charger/maintainers designed for conventional lead acid batteries as these can cause serious damage to your battery. Continuous output trickle chargers can be used but should be disconnected once the battery is fully charged.

Can I use a Lithium battery on any motorbike?
Lithium batteries are actually far more sensitive to overcharging than conventional lead acid batteries and therefore are best not be used with older bikes with mechanical voltage regulators as you risk overcharging and damaging the battery. They should only be used on newer bikes with sophisticated modern charging systems - if you unsure please contact us for advice.

Why is there a difference between the battery capacity and the lead acid equivalent capacity?
The lead acid equivalent figure is purely quoted for convenience and is an indication of the capacity of lead acid battery it would be suitable to replace. For example an LFX14L2-BS12 has a capacity of 4.4Ah but gives the performance of a 14Ah lead acid battery.
