The Guardian family of lithium-ion batteries are targeted at rack-mount installations in the telecom and data center industries. It consists of three sizes — ranging from 2-rack unit (RU) to 4-RU heights, fits in both 19-inch or 23-inch cabinets, and supports capacity ranges from 105 Ahr to 175 Ahr. The batteries provide a nominal 48-V output and will both charge and discharge up to 100 A. Each Guardian battery also contains an integrated battery management system (BMS), charging electronics, and proprietary energy balancing technology (EBT) that enables active current control, load sharing, and state of charge balancing across connected units. All Guardian batteries have active thermal management and feature either lithium nickel manganese cobalt (NMC) and lithium iron phosphate (LFP) chemistries to accommodate multiple telecom and data center applications.
