APC SRTL50RMBP1ULI UPS Lithium-Ion Battery Pack 1U

SKU CH-7YHH-089CK MPN SRTL50RMBP1ULI

Lithium-ion external battery pack adds extended runtime to compatible Smart-UPS Ultra systems, supporting up to five connected units

  • Lithium-ion chemistry in 1U rack form
  • Connect up to five packs for scalability
  • Designed for Smart-UPS Ultra 2KVA and 3KVA
  • New condition with APC reliability

Product Identity

The APC SRTL50RMBP1ULI is a 1U lithium-ion external battery pack designed to extend the runtime of compatible Smart-UPS Ultra systems. It targets IT administrators managing rack-mounted power infrastructure who need scalable backup capacity for 2KVA and 3KVA units.

Critical Compatibility

This pack connects exclusively to Smart-UPS Ultra 2KVA and 3KVA models and supports a maximum of five units in a single chain. It will not function with other UPS families, standard Smart-UPS lines, or as a standalone power source for connected equipment.

Installation Reality

The 1U rackmount form factor slides into standard server racks and uses the proprietary cabling supplied with the host UPS. Common issues include exceeding the five-unit limit, mixing with incompatible battery types, and failing to configure the UPS management card to recognise the added runtime.
