UL1973 / UL9540 / UL9540A Certified · CEC & SGIP Listed

RUiXU Lithi2-16 51.2V 314Ah LiFePO4 Battery Energy Storage

The RUiXU Lithi2-16 packs 16.07kWh of LiFePO4 capacity into a wheeled, wall-mountable battery rated for ≥9,500 cycles at 80% depth of discharge. Built-in Fuma wheels make it easy to move into place, and an anti-tip wall anchor keeps it secure once installed — indoors or out, thanks to its IP55-rated, electro-coated steel enclosure.

A built-in BMS communicates over RS485/CAN with most major inverter brands, including Victron, SMA, Sol-Ark, Solis, Deye, Growatt, Goodwe, and Sunsynk. The Lithi2-16 is expandable up to 32 units in parallel for roughly 512kWh of total storage, making it equally suited to a single home backup system or a larger commercial installation. Renewable Outdoors is an authorized RUiXU dealer, and every Lithi2-16 we sell is backed by RUiXU's 10-year limited warranty.

Why the Lithi2-16 Stands Out

Expandable to ~512kWh

Connect up to 32 units in parallel to scale from a single residential battery to a full commercial energy storage system.

Gas Aerosol Fireroof Protection

An internal fire-suppression module improves fire protection for both the electrical wiring and the battery cells.

IP55 Outdoor-Ready Enclosure

An electro-coated steel case resists rust and corrosion, using the same coating process common in automotive body shells.

Tool-Less Quick Plugs

250A continuous overcurrent capacity with long-term anti-loosening and heating protection, for an easy, secure connection.

Built-In Wheels + Wall Anchor

Four concealed heavy-duty Fuma wheels make it easy to move into place, with an anti-tipping wall mount for secure installation.

Self-Heating & Smart Balancing

Keeps the battery charged in cold temperatures, with intelligent double-equilibrium cell balancing for reliable long-term performance.
