Your server room can't afford a three-week wait for a battery swap. This lithium-ion pack drops straight into your SRTL 1–3 kVA Smart-UPS and triples the runtime you get from a standard VRLA. Fifty amp-hours of energy density in a compact 2U external frame. Rack or tower — your call. Ships with the rail kit, comms cable, grounding cable, and brackets so it's not a half-day install. UL 1973 certified. Operating range 0–40 °C
