EcoFlow DELTA Pro Ultra Battery 6144Wh, LFP LiFePO4 Extra Battery, Whole-Home Energy Storage Expansion – EF-DELTAPROULTRA-EB

Product details

The EcoFlow DELTA Pro Ultra Battery 6144Wh is a dedicated expansion battery designed for the EcoFlow DELTA Pro Ultra whole-home energy storage system.

With a substantial 6144Wh / 6.144kWh capacity, the battery adds significant energy storage to a compatible DELTA Pro Ultra system, allowing connected appliances and devices to operate for longer between charging sessions.

The battery uses LFP (Lithium Iron Phosphate / LiFePO4) cell chemistry, providing a durable solution for repeated charging and discharging. EcoFlow’s official specifications state that the battery can maintain 80% or more state of health after 3500 cycles under specified testing conditions of 0.5C/0.5C at 25?C.

An integrated Battery Management System (BMS) provides monitoring and protection against overvoltage, overload, overtemperature, short circuit, low temperature, low voltage and overcurrent conditions.

The DELTA Pro Ultra Battery features a modular and stackable design, allowing additional batteries to be added within the supported DELTA Pro Ultra system configuration. The original DELTA Pro Ultra platform supports up to 30kWh total battery capacity, using up to five 6144Wh batteries with one compatible inverter system.

The battery connects to the compatible DELTA Pro Ultra system through the designated EcoFlow battery connection interface. Solar panels and AC charging should not be connected directly to this expansion battery; charging is handled through the compatible DELTA Pro Ultra system and its supported charging inputs.

With its 6144Wh capacity, LFP chemistry, integrated protection and modular design, this battery is suitable for home backup, solar energy storage, workshops, off-grid setups, emergency power systems and other applications where additional energy storage is required.
