XESS RM (Roof Mount) Energy Extender Series increases range up to 3 times. If your battery range is 300 mi this product could give you an additional 900 mi.

The RM series of XESS systems are designed to provide extended miles range to any EV or Hybrid with roof rack attachment points and are charged using your home or public charge point. The units are available in sizes from 60 to 100 kWh of electric power and ship complete with everything needed to connect to your vehicle and store the unit when not attached. NOTE: a dealer option to install a power connector in parallel with your vehicle’s battery output is required, not provided by Daheco. All RM series units rigidly attach to the vehicle via the supplied roof rack adapters. Installation is a one person operation where the unit comes with a ceiling mounted hoist system to lift and lower the unit to/from the vehicle. When not attached to the vehicle these units offer backup power for your home or business through your home battery charger (must be bidirectional) adding value to ownership. These units communicate to an app to provide system information on your phone. For some models the dealer option provides an interconnect to integrate the system into the vehicle’s command center.
