    The APC SMX48RMBP2U is a 48V external battery pack that extends runtime for compatible APC SMX Smart-UPS systems rated up to 1500 VA, making it suitable for businesses and IT teams protecting critical equipment during power outages.

    Recommended For

    • Owners of a compatible APC Smart-UPS X/SMX who need longer battery runtime for connected servers, network equipment, or other critical devices during outages.
    • Small-business and IT teams that want to add battery runtime to an existing supported UPS as backup needs grow, rather than replace the UPS.
    • Home-lab operators with a compatible SMX UPS who want to extend runtime for a rack of equipment during longer outages.
    • Rack or tower UPS users with room for a substantial battery pack who prefer to add runtime in stages; compatible systems can support multiple packs, subject to the UPS model’s limits.
