CyberPower Extended Battery Module

The CyberPower BP48VP2U02 is an extended battery module built for IT managers, small business owners, and anyone who relies on an uninterruptible power supply to keep critical gear online. Pair it with a compatible CyberPower UPS and you gain extra runtime that can carry servers, network switches, or other essential electronics through lengthy outages.

Inside the 2U enclosure you will find eight sealed lead-acid batteries, each rated at 12 V and 9 Ah, working together to deliver a 48 V output. When mains power returns, fast-charging circuitry brings the batteries back to full capacity quickly, so you are ready for the next event. CyberPower also adds battery equalization technology that balances the charge across all cells, a process that helps slow down capacity loss and extends overall service life.

Installation is straightforward whether you slide the module into a standard rack or stand it upright beside a tower-style UPS. Hot-swappable batteries mean you can replace a worn pack without powering down connected equipment, and the front panel opens without tools for routine checks or swaps. A three-year limited warranty from CyberPower rounds out the package and adds confidence that your investment is protected.
