Add runtime capacity where it matters most with the CyberPower BCT6L9N225 modular battery cabinet. Designed for 10-40 kVA 3-phase UPS systems, this cabinet supports up to 12 battery modules and gives infrastructure teams a flexible way to scale backup power without redesigning the room. It can be used as a stand-alone cabinet, rack mounted, or stacked with another component in a modular UPS system, making it easier to fit into existing electrical layouts. The cabinet delivers 240 V DC output and uses VRLA battery characteristics for dependable stationary power storage. Hot-swappable support helps reduce service disruption during maintenance, while the black enclosure and modular format fit cleanly into enterprise power rooms. For teams managing critical loads, the value is not just capacity — it is the ability to expand runtime in a controlled, serviceable way. This is the right choice when a standard battery string is not enough and uptime requirements justify a cabinet built for growth, service access, and integration with larger 3-phase UPS deployments.
