Prewired Backplates

Skip to view product listing below.

Prewired controller backplates are designed to maximize battery life and help you avoid the hassle of sourcing, building, and testing your own controller assembly, saving you labor, time, and money.  Our prewired controller designs are field-tested and each backplate has already been tested and inspected for quality assurance. We stock a range of prewired controllers for immediate shipping that are ready to connect to your battery system.

If you have any questions about prewired backplate assemblies or need one custom-designed, please email us at or call 888.680.2427 during regular business hours and we'll be glad to assist you.
