RUiXU Lithi2-16 | 16kWh Outdoor LiFePO4 Battery | IP65 Self-Heating | 51.2V
⚡ Before You Buy
Standalone battery — requires a compatible 48V hybrid inverter to function. Cannot power your home on its own. Confirm inverter compatibility before ordering.
The RUiXU Lithi2-16 is a 16kWh outdoor-rated LiFePO4 wall-mount battery with IP65 weatherproofing and a built-in self-heating system for cold climate performance. At 51.2V 314Ah, it pairs with most 48V hybrid inverters including the Sol-Ark 12K/15K, MidNite TheOne, and Growatt SPH series.
IP65 outdoor rating means it can be installed on an exterior wall, garage, or utility area without additional weatherproofing. The self-heating system engages automatically when temperatures drop below the battery's optimal charge range — critical for New England and northern climates where unheated garage installs are common. At 16kWh usable capacity, one unit covers 8–16 hours of essential load backup depending on your home's consumption.
