The 48VDCSPLITTER Y Splitter Cable connects two Tripp Lite external battery packs to a compatible UPS system to extend runtime. It is compatible with Tripp Lite's non-expandable BP48V24-2U and other select battery packs that specify compatibility with this cable. The one-foot (30.5 cm) 48VDCSPLITTER is constructed using 4 AWG two-conductor black cabling. It features three blue 175A DC connectors: two outputs for the battery packs and one input for a UPS system that specifies the use of a BP48V24-2U battery pack.
