Need a Shorai Battery Charger?

Maintain your battery with a compatible lithium charger, such as the Deltran 12 Volt, 1.25 Amp Battery Tender. Avoid chargers with desulfation modes that cannot be disabled.

Frequently Asked Questions

What applications are Shorai batteries used for?

A: Shorai lithium batteries are intended for use as powersports batteries, perfect for a wide range of vehicles, including:

What is lithium iron, and how does it compare to other lithium batteries?

A: Shorai batteries use lithium iron phosphate (LiFePO4) technology, a type of lithium-ion chemistry known for its stability, safety, and resistance to temperature extremes. Unlike lithium cobalt oxide cells used in electronics, LiFePO4 batteries are ideal for motorcycles because they provide consistent performance and improved heat tolerance.

What makes Shorai LFX batteries different?

A: Shorai LFX batteries use proprietary prismatic cells, not cylindrical cells made for power tools like many competitors. This allows Shorai to build batteries in precise shapes and sizes for better fitment. LFX batteries are lighter, have a lower self-discharge rate, and come with foam shims for a snug, OEM-like installation. Each battery is produced in an ISO-certified facility and tested extensively to ensure long-term reliability.

How does Shorai performance compare to lead-acid batteries?

A: Unlike lead-acid batteries that lose voltage quickly under load, Shorai batteries maintain higher voltage during cranking. This translates into faster starts, even in cold conditions, with up to two volts more delivered than an equivalent lead-acid battery. Riders notice stronger, more consistent performance with less wear over time.

How do Shorai motorcycle batteries perform in cold weather?

A: All lithium batteries see higher resistance in low temperatures, but Shorai’s design helps them recover quickly. If the first crank is weak in cold conditions, the battery warms itself and delivers more power on the next attempt. Many riders also “wake” the battery by turning on headlights or heated gear for a short time before starting, which improves performance and extends battery life.

Are Shorai batteries easy to install?

A: Yes. Shorai includes adhesive-backed foam shims to ensure a snug fit if the battery case is smaller than your original. This makes installation simple, without modifications or special tools. For step-by-step help, see our installation guide and video.
