You Buy Manufacturing Capability, Not A Fixed Product

Every cabinet on this page was built for a specific project. Your dimensions, materials, protection grade, door layout and cable entries are all decided by you — we handle structure design, process planning, fabrication and testing. This page shows what we have done and what we can do for your project.

  • SPCC cold-rolled steel, 1.2–2.0mm thick
  • IP54–IP65 protection, salt-spray tested
  • Precision CNC bending, ±0.1mm tolerance
  • Full welding + powder coating finish
  • In-house tooling & stamping capability
  • One-stop: design → fabrication → assembly

Product Overview

Industry Pain Points We Solve

  • Off-grid and mobile applications require rugged, stackable battery enclosures that withstand vibration and transport stress.
  • Thin gauge steel cabinets deform under stacked load, damaging battery modules and compromising structural integrity.
  • Poor thermal design causes heat buildup in densely packed battery arrays, triggering BMS shutdowns.
  • Standard enclosures lack proper cable management and busbar access for series-parallel configurations.
  • Imported cabinets have long lead times and inconsistent quality, delaying deployment schedules.
  • Corrosion from outdoor and marine environments reduces service life and voids battery warranties.

Our Core Manufacturing Strengths

  1. Free structural CAD design – engineers optimize stacking load paths and mounting points at no cost, unlimited revisions.
  2. 2.0mm SPCC steel, +/-0.1mm precision – laser cutting at +/-0.05mm and CNC bending at +/-0.1mm for precise panel alignment.
  3. Stackable structural design – reinforced corner posts and base channels support multi-layer battery stacking.
  4. Weather-resistant powder coating – 60-80um coating with 500-hour salt spray resistance for outdoor deployment.

Application Scenarios

Our stackable mobile energy storage cabinet enclosures are used in portable power stations, solar generator systems, RV and marine battery banks, construction site power, emergency backup systems, and off-grid installations. Each cabinet is custom-sized for your specific battery module dimensions and stacking configuration.

😩 Typical Buyer Pain Points

  • No structural drawings ready for battery rack integration
  • Cabinet deformation under heavy battery module weight
  • Poor thermal design causing cell overheating and derating
  • Water ingress risking catastrophic battery damage
  • Fire safety gaps failing local certification
  • Long lead times delaying your BESS project rollout

Frequently Asked Questions

What is the minimum order quantity?
MOQ is 1 piece. We welcome prototype and small-batch orders so you can validate the design before scaling up.
Can you design the cabinet if we don't have drawings?
Yes. Free production-ready CAD drawing design is our core service. Provide your power module dimensions, weight and layout requirements, and our engineers will produce manufacturable drawings for your confirmation.
What drawing formats do you accept?
We accept STEP, IGS, DWG, DXF and PDF sketches. Even a hand sketch with key dimensions is enough to start.
How do you quote? What are the payment terms?
Factory-direct quotation within 24 hours of receiving your requirements. Payment by T/T (30% deposit, 70% before shipment). FOB, CIF and DDP shipping terms supported.
What is the typical lead time?
Samples take 7–10 days; mass production takes 15–25 days depending on quantity and surface treatment requirements.
Can the cabinet achieve IP55 or higher protection?
Yes. Our standard sealing design reaches IP54–IP55, and we can upgrade gaskets, cable glands and door structures for harsher environments.
Do you ship internationally?
Yes, we export worldwide with export-grade plywood packaging, and we support FOB, CIF and DDP shipping terms.
