Wattbox WB-UPS-EBP-18AH48V External Battery Pack 18ah 48V

Product Description

The WATTBOX WB-UPS-EBP-18AH48V is an external battery pack designed to expand the runtime capacity of compatible WATTBOX uninterruptible power supply systems. Rated at 18 amp-hours (Ah) at 48 volts, this battery expansion unit connects to a host UPS to extend backup power duration during outages or voltage events. It is installed by low-voltage integrators, electricians, and AV or IT technicians in commercial and residential applications where extended runtime is a critical requirement. Each unit is sold individually and ships as a single piece of equipment.

This external battery pack is suited for installations where the base UPS runtime is insufficient for the protected load or the expected outage duration. Typical applications include rack-mounted or wall-installed UPS deployments in control rooms, server closets, AV equipment bays, security system infrastructure, and building automation panels. The 48-volt architecture is common in higher-capacity UPS platforms and supports longer cable runs between the battery and the host unit.

Key Features

• 18 Ah capacity at 48 volts extends backup runtime beyond the host UPS base battery
• Designed as an add-on expansion pack, not a standalone UPS unit
• 48-volt system architecture suitable for higher-capacity UPS platforms
• Sold as a single unit (each) for precise quantity ordering
• Supports extended runtime requirements in commercial and residential installs

Compatibility

Designed as an OEM-matched external battery expansion pack for compatible WATTBOX 48-volt UPS systems. Consult the WATTBOX product documentation to confirm compatibility with the specific host UPS model before ordering.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed electrician familiar with UPS systems and battery handling procedures. De-energize the host UPS and follow the manufacturer lockout procedure before connecting or disconnecting the battery pack. Battery expansion packs must be connected only to the designated battery port on a compatible host UPS — never connect to mains power directly. Local electrical codes and the National Electrical Code (NEC) may apply to the installation environment.
