Bluetti Apex 300 + 350W Portable Solar Panel PV350 Bundle

The B500K Battery Base is a low-profile expansion base designed to stabilize and elevate Apex 300 and 350W portable power setups while adding protected cable routing and accessory mounting. Its rigid, stack-friendly frame improves airflow around your power station, keeps wiring organized, and helps you build a compact, grab-and-go kit for camp, jobsite, or home backup.

Key Benefits

Made for Apex 300 & 350W: Footprint and tie-downs sized for a snug, non-slip fit with Apex 300 and 350W power gear.

Clean Cable Management: Integrated channels keep PV leads, barrel/DC cables, and adapters protected and tidy.

Stack & Stabilize: Low center of gravity with anti-vibration pads helps prevent tip-overs in vehicles and on uneven ground.

Airflow Friendly: Raised chassis improves convection around cooling inlets for better heat dissipation.

Field-Ready Build: Rugged enclosure with scratch-resistant finish for outdoor, travel, and daily use.

Special Technology

Quick-Latch System: Tool-less strap points and corner catches make it fast to dock/undock your Apex unit.

Accessory Rail: Side rail accepts clip-on holders (MC4 pigtails, 12V sockets, small inverters, or radios).

Through-Base Routing: Pass-through openings let you route panel and car-charge leads without pinching.
