The Solar Battery Backup Braking System offers peace of mind with maximum safety during emergency situations. Utility and equipment companies, and anyone who has a trailer with an electric braking system, know that when the trailer disengages from the main transporter the emergency magnetic brake on the trailer must be fully operational. This unit contains the highest quality sealed batteries that are maintained during periods of non-use via the fully encapsulated Solar Maintenance Charger. Additional features include a proprietary momentary push button switch that actuates an indicator light that tells you the battery is charged and ready to go. It is easy to mount, with four mounting holes, and is designed to operate independent of the vehicle’s electrical system. It is durable and corrosion proof. Made of ALMAG 35, which is the same material used on aircraft landing gear, this is simply the best battery backup system in the world.    Cat. No. 3501
