Description
The EcoFlow 2kWh LiFePO4 Battery (EF-PK-B12-1) represents a significant advancement in off-grid energy storage. Unlike standard lead-acid batteries, this LFP unit is designed to handle deep discharges and heavy loads while maintaining a compact and durable form factor. It is specifically engineered to serve as the heart of a modular power system, providing the silent and emission-free energy needed for remote field offices, off-grid cabins, or mobile homes.
Efficiency is a core advantage of this battery’s 48V design. By using a higher voltage, the system experiences less power loss through cables and generates less heat, which is critical for maintaining performance in enclosed spaces. The integrated smart BMS is one of the most advanced in the industry, featuring a "stop-and-protect" mechanism that safeguards the battery from over-discharging, over-charging, and short-circuiting, significantly extending the hardware's lifespan.
The EF-PK-B12-1 is built for durability in all climates. Its rugged, fire-retardant shell and innovative self-heating technology ensure that whether you are in a high-altitude mountain retreat or a coastal cabin, your energy supply remains stable. For those looking for a scalable energy solution, the stackable design allows you to start with 2kWh and grow your system as your power needs increase. It is the smartest, safest, and most efficient choice for anyone building a serious off-grid or backup energy ecosystem.
