Bluetti B700 spare battery

The Bluetti B700 additional battery is a battery module for the EnergyPro 20K EP2000 energy storage system. It is used to increase the energy capacity of a domestic or commercial ESS system, allowing critical loads to be maintained for longer during power cuts, utilising more stored solar energy and reducing dependence on the mains grid.

The module has a capacity of 7.3 kWh, making it a core component for building a scalable Bluetti EP2000 system. In the EnergyPro 20K configuration, B700 batteries can be combined in varying quantities, providing a total system capacity ranging from 14.7 kWh to 51.6 kWh in a standard configuration of 2–7 batteries. This allows you to select the right energy capacity for a specific home, load and usage scenario.

The battery is based on LiFePO4 technology. Lithium iron phosphate batteries are well suited for stationary energy storage systems, as they are designed for long-term operation, offer stable performance and a high level of safety. This type of battery is particularly suitable for systems that operate daily: storing solar energy, powering the home during peak hours, or providing a backup during power cuts.

The Bluetti B700 is compatible with the EP2000 hybrid inverter. Together, these components form the EnergyPro 20K system, which can operate with a three-phase connection, solar panels, a backup power supply and scalable battery capacity. The battery is not a standalone portable charging station, but rather part of a stationary home energy storage system.

Thanks to its modular design, the user can gradually increase the capacity. For example, a configuration with 2 batteries provides approximately 14.7 kWh, with 3 batteries — 22.1 kWh, with 4 batteries — 29.49 kWh, with 5 batteries — 36.86 kWh, with 6 batteries — 44.2 kWh, and with 7 batteries — 51.6 kWh. This is convenient for homes with varying levels of electricity consumption.

The IP65 protection rating enhances the reliability of the battery module and protects the housing from dust and moisture. This is important for equipment installed in technical rooms or protected outdoor areas. The operating temperature range is from -20°C to +50°C, allowing the battery to be used in various climatic conditions.

The battery dimensions are 670×280×386 mm, and it weighs 72 kg. This is a stationary battery module that requires correct positioning, connection to a compatible inverter, and professional installation as part of an energy storage system.

The Bluetti B700 comes with a 10-year warranty. This underscores the battery’s focus on long-term use in domestic and commercial power systems. The module is well-suited for users who wish to create a reliable backup power system, solar energy storage solution and achieve energy independence.

The Bluetti B700 is a key battery module for the EP2000 EnergyPro 20K system. It combines a capacity of 7.3 kWh, LiFePO4 technology, IP65 protection, a wide operating temperature range and a 10-year warranty. It is a practical solution for scaling up a home ESS system and increasing autonomy during power cuts.
