Needed to replace my YB12AL motorcycle battery and wanted a lithium replacement, for better CCA and over-winter storage. Go Batteries came up in my internet search and were one of tge few that offered a lithium battery (Shido) of similar dimensions to a YB12AL standard battery. Went with it, and battery arrived very quickly with great tracking comms. Have to say I like the Shido battery, as it offers 4 terminals, like Motobatt does and, surprisingly, a battery test button/monitor which lets you instantly see the battery status. Perfect. So, all in all, a great battery, provided by a good company who deliver quickly. Will use Go Batteries in future.
