Common questions

Is this a 16kWh-class battery? Yes. Its published nominal energy is 16.07kWh, while usable runtime depends on the system settings and loads.

Can I add another battery later? RUiXU describes parallel expansion, but consult the manual and confirm the number of units supported by your battery revision and connected equipment.

Can Lithi2-16 connect to RUiXU RX-12K?

RUiXU explicitly lists its RX-CB-US conduit box for a Lithi2-16 battery paired with an RX-12K inverter. Its published battery communication guidance includes RX-12K setup. See the RX-12K inverter and manufacturer conduit-box listing for the exact model relationship.

That is a documented pairing, not a universal 48V-battery approval. Confirm current firmware, communication cable and protocol, battery count, current protection and installation instructions for the units being installed. RUiXU asks buyers to consult its technical support about other battery brands before treating them as compatible.

Frequently Asked Questions

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

How much energy does the RUiXU Lithi2-16 store? It is rated at 51.2V, 314Ah, and 16.07kWh of nominal energy. Actual usable energy depends on BMS limits, system reserve, temperature, discharge rate, and inverter settings. How many Lithi2-16 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. Does the Lithi2-16 have a local display? Yes. It includes an onboard LCD touchscreen for battery information and quick-plug connections for supported system wiring. How large and heavy is the Lithi2-16? It measures 36.3 × 21.3 × 10 in with wheels and weighs 302 lb. Plan the floor or rack loading, handling equipment, clearances, ventilation, and service access before delivery. What warranty applies to the Lithi2-16? 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. Is the Lithi2-16 documented for the RUiXU RX-12K inverter? Yes. RUiXU lists an RX-CB-US conduit box for the Lithi2-16/RX-12K pairing and publishes communication setup guidance. Confirm current firmware, cable and protocol settings, permitted battery quantity and installation details before commissioning. Do not assume the same settings apply to other inverter models.
