48 V 27 Ah external battery pack

The Tripp Lite BP48V27-2US is a 48 V DC external battery pack designed to extend the runtime of compatible Tripp Lite UPS systems. It suits administrators managing SMART and SMX series units such as the SMART3000RM2U or SMX3000XLRT2U. The pack delivers 27 Ah capacity and fits 2U rackmount installations with included four-post accessories.

Sustained runtime extension

Under continuous load the pack works with the UPS to provide extended backup time rather than a momentary bridge. Its rated battery life spans four to six years, so capacity remains stable across repeated discharge cycles. The daisy-chain connector allows additional packs to be linked for further runtime without changing the UPS configuration.

48 V DC interface limit

The pack operates strictly at 48 V DC and only connects to the listed Tripp Lite UPS models. It cannot be used with units that require a different bus voltage or lack the proprietary daisy-chain port. Physical weight of 88.10 lbs means the rack must support the mass, and the 2POSTRMKITWM accessory is required for balanced two-post centre mounting.

Questions about this item

How much heat or fan noise does the BP48V27-2US generate during continuous operation?

The pack is a passive 48 V DC battery bank with no internal fans or active cooling, so it adds no audible noise or measurable heat beyond normal battery warmth during extended runtime.

Which UPS units must I already own for this external battery pack to function?

It connects only to compatible 48 V Tripp Lite UPS systems such as the SMART1500CRMXL, SMART2200RMXL2U, SMART3000RM2U, SMART5000RT3U and the other models listed in the compatibility table.

Can I add this pack alongside an older Tripp Lite UPS that uses a different battery voltage?

No — the BP48V27-2US supplies 48 V DC and the daisy-chain connector works solely with UPS units designed for that same 48 V architecture; lower or higher voltage models cannot use it.
