It boasts deep cycle capabilities (2,000+ cycles) and a wide operating temperature range for demanding climates. It arrives fully charged and ready to install, with a built-in BMS to manage charging and discharging safely.
Best for: riders with high starting demands and larger battery compartments who want strong CCA and extended service life. Limitation: ensure the mounting space and terminal layout match the vehicle’s original setup to avoid fit issues.
Why selected
- Higher CCA and capacity for powerful starts
- Long cycle life and fully charged out of the box
- BMS protection for safer operation
Buying Guide
What should I look for in a lithium motorcycle battery?
Key factors include capacity (Ah), cold-cranking amps (CCA), weight savings, size compatibility, BMS protection, and maintenance requirements. A higher CCA helps with cold-start performance in chilly conditions, while a larger Ah rating supports longer accessory operation between starts.
Will a LiFePO4 battery fit my bike?
Match the physical dimensions to your battery tray, verify the terminal positions (positive/negative), and confirm the mounting pattern. If the installation space is tight, consider batteries with adjustable spacers or universal-fit brackets.
What about protection and longevity?
Choose batteries with a built-in BMS (battery management system) to guard against overcharge, over-discharge, short circuits, and cell balancing. This improves longevity and reliability in varied riding conditions.
Maintenance and charging considerations
Most LiFePO4 batteries are maintenance-free and arrive pre-charged. Use appropriate chargers designed for lithium chemistry to avoid charging at inappropriate rates. Avoid deep discharges that exceed the manufacturer’s recommended DOD thresholds.

FAQ
- What is the main advantage of lithium motorcycle batteries over lead-acid?
Lithium batteries are lighter, provide higher energy density, offer longer cycle life, and require less maintenance.
- Do lithium batteries need special chargers?
Yes. Use a charger designed for lithium chemistries to prevent overcharging and to protect the BMS.
- Can lithium batteries be used in extreme temperatures?
Many LiFePO4 batteries perform well across wide temperature ranges, but always check the manufacturer’s operating limits for cold starts and charging.
- How do I know if a battery fits my bike?
Compare dimensions, terminal layout, and CCA/ah with your original battery and mounting space.
- Is a higher CCA always better?
Higher CCA improves cold-start performance but must align with your bike’s electrical system requirements to avoid over-specification.
