RX-LFP48100 · Buyer decision facts

RUiXU RX-LFP48100 | 5.12kWh Rack LiFePO4

The RX-LFP48100 stores 5.12kWh nominal at 51.2V and 100Ah in a 3U rack module. Its 100A maximum discharge and 70A maximum charge ratings affect inverter and charger sizing for a single module.

RUiXU describes up to 32 matching modules in parallel under its system rules. Check cabinet fit, communication cable, inverter BMS protocol and required battery quantity; a 48V-class match alone is not proof of compatibility.

For built-in heating, compare the RX-LFP48100-H.

What comes with the RX-LFP48100

  • RX-LFP48100 server-rack battery
  • RJ45/CAT5e patch cable
  • Ground cable
  • Set of parallel 4 AWG cables per battery

Plan the battery bank

Each module stores 5.12kWh nominal. Confirm the inverter’s supported BMS protocol, rack or cabinet fit, and cable arrangement before buying multiples. The RX-LFP48100-H is the version with self-heating for cold-weather charging.

Common questions

Is this the heated version? No. This is the standard RX-LFP48100; choose RX-LFP48100-H when the self-heating feature is required.

Does a 48V inverter automatically communicate with it? No. Confirm the exact inverter protocol and wiring in the battery and inverter manuals.

Frequently Asked Questions

Clear answers to common questions about this product, setup, compatibility, and use.

How much energy does the RUiXU RX-LFP48100 store? It is rated at 51.2V, 100Ah, and 5.12kWh of nominal energy. Actual usable energy depends on BMS limits, system reserve, temperature, discharge rate, and inverter settings. How many RX-LFP48100 batteries can be connected together? RUiXU lists up to 32 matching units in parallel. Follow the manufacturer's communication, cable, overcurrent-protection, firmware, state-of-charge, and commissioning procedure. Can the RX-LFP48100 communicate with an inverter? It supports CAN and RS485 communication for compatible inverters. Confirm the exact inverter protocol, cable pinout, firmware, and battery settings before commissioning. How large and heavy is the RX-LFP48100? It measures 19 × 18.1 × 5.23 in / 3U and weighs 103.6 lb. Plan the floor or rack loading, handling equipment, clearances, ventilation, and service access before delivery. What warranty applies to the RX-LFP48100? RUiXU lists a 10-year warranty. Coverage depends on the current warranty terms and correct system design, installation, charging, operation, temperature, and storage. Can it communicate with every 48V inverter? No. Nominal voltage alone does not guarantee closed-loop compatibility. Verify the exact inverter model, supported protocol, cable, firmware, battery quantity, and configuration.
