Power up your Apex 300 with the 5.12 kWh B500K expansion battery and add flexible DC distribution with the Hub D1. This bundle scales your portable/home backup system, enabling longer runtimes, fast 120 V/240 V operation from the Apex 300, and direct 12–50 A DC outputs for RV and off-grid gear.

Key Benefits

Major Capacity Boost: Add 5,120 Wh of LFP storage to Apex 300; expand further as needs grow (up to multi-pack systems). 

Direct DC Power Hub: Hub D1 provides up to 700 W total across RV/Anderson, cig/DC5521, and USB ports—run DC loads without using the inverter.

Long-Life Chemistry: LiFePO₄ cells with thousands of cycles for dependable, safe storage.

Bluetti Hub D1: 

• 700 W Total DC Power: Power everything from diesel heaters to laptops with USB-A, USB-C, DC5521, Cigarette Lighter, and Anderson port.
• 12 V/50 A (24 V/25 A) Anderson Port: Drive more high-current devices like fridges and rooftop A/Cs — perfect for RVs, boats, and off-grid systems.
• Simplified Power Supply: No more complex wiring or guesswork — just plug, power, and go.
• Secure Connection: The Anderson 50 A port ensures a lock-fit connection, preventing accidental disconnects or arcing even on rough roads.
• Flexible Setup: Clip onto Apex 300 or mount on a wall — your DC ports go wherever you need them.

Applications

Home Backup: Extend outage runtime for refrigerators, lighting, networking, and essentials.

RV & Vanlife: Use Hub D1’s RV (50A Anderson) and 12 V ports to power fridges, comms, and accessories off-grid. 

Job Sites & Events: High AC output from Apex 300 with extra battery reserve for tools and AV gear. 

Installation

Plug-and-Play: Connect B500K to Apex 300 with the expansion cable, then add Hub D1 to the system. Mount B500K on shelf/wall or use a trolley; follow manufacturer torque and polarity guidelines. 

Special Technology

Modular Ecosystem: B500K works across BLUETTI platforms (Apex 300, AC300/AC500/AC200L) and pairs with smart accessories like SolarX and Hub D1.

Dual-Voltage Capability (Apex 300): 120/240 V operation for flexible household and RV loads.
