Lithium Iron Extreme-Rate Battery

Shorai LFX batteries come in a variety of case shapes and sizes, capacity options and right/left polarity options for the best possible fitment. If the LFX is slightly smaller than the original battery in one dimension or another, high-density, adhesive-backed foam sheets are included in the package. These can be trimmed and applied to the battery box in minutes to make a solid fit and with added thermal and vibration insulation. Cable connections can be made either at tops or sides of the terminals. All these options and sizes allow Shorai LFX to offer a drop-in installation for most powersports vehicles. We also offer a 6-volt LFX in the #2 case size for vintage vehicles.

Standard recommendation is the best overall pick for most applications and gives long lifespan. Duration recommendation gives stronger cranking performance over standard recommendation (Where applicable).

When you open a LFX battery package you will also find terminal screws and a set of spares, Shorai decals in various sizes and the user manual.

Self-adhesive foam shims insure a great fit to the battery box, as well as extra vibrational and thermal insulation.
