Because of the potential size difference between an OEM battery and a Shorai 12V LFX battery, an extension Shorai charger cable kit may be necessary to properly fit a LFX battery in an OEM battery box. The extension Shorai charger cable kit is also ideal for Shorai battery owners with more than one motorcycle in storage. Featuring two cables – one extension cable and one charge cable permanently attached to the battery – owners with multiple motorcycles can use the extension cable kit to conveniently charge batteries from a single Shorai charger.
