RX-LFP48100 Spec Sheet

UL1973 Certified · UL9540A Tested · CEC & SGIP Listed

RUiXU RX-LFP48100 19" Server Rack Mounted 3U Module

The RUiXU RX-LFP48100 is a 48V, 100Ah (5,120Wh) LiFePO4 battery module built for standard 19-inch server racks. Its 3U form factor drops straight into telecom cabinets, data centers, and renewable energy setups that need modular, scalable backup power without a custom enclosure.

Up to 32 modules can be connected in parallel — scaling from a single 5.12kWh module to a 160kWh bank — without an external controller, and DIP address switches make it easy to set the RS485 baud rate and inverter protocol. Renewable Outdoors is an authorized RUiXU dealer, and every RX-LFP48100 we sell is backed by RUiXU's 10-year limited warranty. Need cold-weather charging? See the self-heating RX-LFP48100-H variant.

Why the RX-LFP48100 Stands Out

Standard 19" 3U Rack Fit

Drops straight into a standard 19-inch server rack — no custom enclosure or mounting hardware needed.

Scales to 160kWh

Connect up to 32 modules in parallel — from a single 5.12kWh unit to a 160kWh bank — without an external controller.

Wide Inverter Compatibility

Canbus and RS485 support covers most major brands, including Victron, SMA, Sol-Ark, Solis, Deye, Growatt, and Sunsynk.

Simple DIP-Switch Setup

Set the RS485 baud rate and choose your inverter protocol with onboard DIP address switches — no separate software required.

UL1973 Certified

UL1973 certified and UL9540A tested, with CEC and SGIP program listing for eligible rebate and incentive programs.

Ready to Install

Ships with a patch cable, ground cable, and a set of parallel 4AWG cables per battery, so you can rack it and wire it the same day.

RUiXU's spec sheet and manual for this module are referenced on their product page but not linked to a direct, verifiable manufacturer PDF at this time — cycle life, charge current, and operating temperature figures weren't available in text form, so they've been left off this table rather than guessed. We'll add them once a direct manufacturer link is confirmed.

10-Year Warranty

Every RX-LFP48100 we sell is backed by RUiXU's full 10-year limited manufacturer warranty.
