ElectricRider builds and assembles lithium batteries in-house to assure quality in every aspect. Almost all batteries are built "to order" based on the customers' request for shape or size. Lithium Batteries can be assembled in various configurations, such as long and narrow vs. short and wide. Building our own batteries allows us maximum control over every process involved, and every process is important. ElectricRider can usually accommodate size or shape requests for no additional charge. If an additional charge will be applied to a custom battery build, we will inform you before the order is finalized.
