RUiXU RX-LFP48100-H 48V 100Ah 5.12kWh Self-Heating Server Rack Lithium Battery

The RUiXU RX-LFP48100-H is a 19 inch rack-mounted LiFePO4 battery with built-in self-heating, letting it safely accept a charge in temperatures down to -20°C (-4°F) — a must-have if this battery lives in an unheated shed, garage, or outbuilding through a cold winter. Its compact 3U form factor stacks cleanly into a standard server rack or RUiXU's dedicated battery cabinets, and it communicates natively with most major inverter brands.
