• Perfect for space-saving installations

The Bluetti B500K2 expansion battery (MPN P-B500K2-EU-GY-20) is the ideal solution to flexibly expand the capacity of your power station. With a capacity of 5,120Wh, the B500K2 provides sufficient energy for a wide range of applications and adapts effortlessly to your energy needs. Thanks to the durable LiFePO4 technology and prismatic cells, the B500K2 delivers reliable performance in every situation. The integrated AI-BMS technology ensures optimal protection and high efficiency. Additionally, the support for pass-through charging enables simultaneous charging and discharging, so you can access a stable energy source at any time.

• Highlights of the B500K2 expansion battery
• Modular and expandable
• Extended lifespan with automotive-grade LiFePO4 battery
• Wall mounting possible
• Integrated USB-A port

Thanks to the integrated USB-A port, the B500K2 enables charging of DC devices directly via USB. For AC charging, a combination with a power station is required.

• Difference to B500K1 (cable & compatibility)

The difference between B500K2 and B500K1 lies in the included connection cable: The K2 variant is supplied with a short connection cable that is particularly space-saving and ideal for surface mounting. The K2 version is specifically intended for connection to the Apex300 power station and for coupling multiple expansion batteries together. Connection to other power stations (e.g. AC500, AC300 etc.) is not intended with the K2 variant – for this, the K1 version with long cable is required.

• Compatibility

The B500K2 expansion battery is compatible with the Bluetti Apex300 power station and all other expansion batteries of the B300K/B500K series. The K2 variant is ideal if you want to connect multiple batteries in a space-saving way or directly to the Apex300.

• Expandability and modularity

Up to 8 B500K2 expansion batteries can be modularly combined to increase the total capacity up to 40,960Wh as needed (maximum expansion level, see manufacturer's specification). The expansion is simple and flexible, so you can individually adapt your energy supply.

• Total capacity
• Fast charging time

In connection with the Apex300, the B500K2 charges particularly quickly. This fast charging time is especially advantageous when you need to handle important work, activities, or emergencies without major interruptions.

• Mounting

The battery is easy to mount, both for use at home and in a motorhome, and its efficient thermal management ensures smooth operation even under intensive use through heat dissipation.

The efficient thermal management protects the battery from overheating and contributes to its longevity. Even under intensive use, operation remains safe and reliable.

• Discharge

The B500K2 has an energy reserve that prevents over-discharge. This extends the battery's lifespan and ensures long-term performance.

What is AI-BMS?

The integrated AI-BMS (Battery Management System) monitors the battery in real time and reliably protects it against overcharging, overheating, and other risks – for maximum safety and a particularly long lifespan.

• Advantages of prismatic cells

Prismatic cells offer particularly high safety and stability in operation, making the battery more resistant to external influences and further increasing its lifespan.

• Prismatic cells for increased safety
• Package contents
• 1x Bluetti B500K2 expansion battery
• 1x C90A short battery expansion cable
