Overview

The APC SRTL50RMBP1U-LI is a high-performance 1U lithium-ion battery pack engineered for Smart-UPS Ultra systems. Delivering 50V of backup power in a slim 1U design, it provides extended runtime to safeguard mission-critical IT and network infrastructure. Its lithium-ion technology ensures longer service life, reduced maintenance, and higher resilience compared to traditional VRLA batteries. With flexible mounting options, this unit adapts seamlessly to both rack and tower environments.

Key Features & Benefits

  • 1U Lithium-Ion Design: Compact form factor maximizes space efficiency in rack and tower deployments.
  • 50V Battery Voltage: Provides stable backup capacity for Smart-UPS Ultra systems.
  • Extended Runtime: Delivers prolonged power support to sustain critical loads during outages.
  • Flexible Mounting: Rack, tower, and two-post mountable with included brackets.
  • Durable Lithium-Ion Chemistry: Offers longer lifecycle and reduced replacement frequency compared to VRLA.
  • Lightweight Build: At 19.5 kg, it is easier to install and maintain than traditional battery packs.

Technical Deep Dive

The SRTL50RMBP1U-LI leverages lithium-ion technology, which provides a significantly higher energy density and a longer lifecycle compared to sealed lead-acid alternatives. Lithium-ion batteries maintain consistent output even under high load conditions, reducing the risk of power dips that could disrupt sensitive equipment.

This 50V pack is optimized for Smart-UPS Ultra systems, ensuring seamless integration and intelligent runtime scaling. Its compact 1U design allows data centers and network rooms to preserve valuable rack space without compromising runtime extension.

Engineered for demanding IT environments, the unit operates reliably in ambient temperatures from 0 to 40 °C, supporting deployment in a wide range of facility conditions. Combined with robust humidity tolerance (0–95% non-condensing), it is built for resilience in both enterprise and edge installations.

Ideal Applications

  • Smart-UPS Ultra runtime extension in enterprise data centers
  • Network closets and distributed IT environments
  • Edge computing systems with space-constrained racks
  • Critical infrastructure requiring compact, high-efficiency energy storage
