Battery Enclosure Manufacturing — IP-Rated Lithium-ion Battery Boxes, ESS/BESS Cabinets & Precision Sheet Metal in India

Eterna Global Solutions LLP manufactures high-quality, precision battery enclosures and energy storage cabinets for Lithium-ion battery applications — including IP-rated battery boxes, BMS/controls compartments, inverter/charger housings, and sheet metal assemblies used in EV infrastructure, telecom backup power, solar storage, industrial UPS, and Battery Energy Storage Systems (BESS/ESS).

Battery enclosures are not “normal cabinets”. They must protect sensitive cells and electronics from dust, water ingress, vibration, and thermal stress, while remaining safe, serviceable, and consistent at scale. Eterna has extensive experience in fabricating fully waterproof IP-rated enclosures (including designs targeting IP68 as per customer specification) and achieving intricate profiles that are unusual for metal — made possible through design-stage manufacturability planning, controlled forming, and repeatable CNC production.

We support customers from early engineering to volume supply: laser cutting, CNC bending, welding, sealing features, coating, and assembly-ready packaging. Our design team routinely works alongside customer engineering teams to evaluate the optimal sheet metal solution for strength, sealing, weight, and production cost — so your enclosure performs in the field and remains scalable for long-term supply.

Battery enclosure manufacturing overview

IP protection • precision • scalability • safety-first design.

What makes battery enclosures different

Battery applications require enclosures that protect both cells and electronics. Designs must handle vibration, thermal cycling, outdoor exposure, cable ingress, and service access without compromising sealing. Repeatability matters: a minor gasket compression change can create leakage in the field.

How Eterna supports customer engineering

We support your in-house team by reviewing drawings for DFM, sealing feature feasibility, fastening strategy, and production-friendly construction. This is where intricate profiles and “unusual for metal” geometry becomes practical and repeatable.

Program mindset: Battery enclosures are typically long-running programs. We focus on stable BOMs, process control, and batch-to-batch consistency so your supply remains predictable.

Battery enclosure types we manufacture (click to expand)

Battery boxes • BESS cabinets • control enclosures • custom OEM.

Lithium-ion battery boxesIP-rated • gasketed • serviceable

Sealed battery boxes for indoor/outdoor deployment with designed sealing planes, cable ingress provisions, and mounting brackets.

Prototype to volume programsNPI • pilot batches • long-term supply

We support pilot builds for field trials and scale to stable, repeatable production with controlled processes.

DFM loop: iterate before tooling locks
Repeatability: CNC programs + controlled work instructions
Packaging: transit-safe, assembly-ready dispatch

Design-stage advantage: The best way to hit IP targets and cost targets is to engineer sealing, fasteners, and flatness before production drawings are frozen. That’s where we add the most value.

Sealing strategy for IP-rated battery enclosures

Gasket design • compression control • ingress points.

What we engineer into the metal

Sealing performance depends on flatness, gasket landing area, and consistent compression. We design sealing planes, gasket channels, and compression stops so assembly torque doesn’t over-crush the gasket or leave low-pressure zones.

Ingress points that usually fail

Most leaks happen at cable entries, vents, and service panels. We provision gland plates, cable routing, fastener spacing, and access geometry so the enclosure stays serviceable without compromising sealing integrity.

Field reliability: IP results improve dramatically when assembly uses defined torque, fastener sequence, and controlled gasket specification. We can provide assembly work instructions for production and service teams.

Thermal management & ventilation provisions

Heat paths • venting • fan/filter • passive options.

Thermal reality

Battery systems generate heat in cells and power electronics. The enclosure must support heat rejection while maintaining safety and ingress protection. We integrate mounting points and cutouts for cooling hardware based on your design.

Common provisions we build

Fan/filter mounts, heat exchanger cutouts, louver patterns (where allowed), segregated airflow paths, cable trays that reduce heat hotspots, and service-friendly access panels.

Note: For higher IP targets, venting typically uses rated vents or controlled airflow systems. We manufacture the sheet metal to support whichever approach your design requires.

Materials & finishes for battery enclosures

Strength • corrosion • coating compatibility.

Common metals

CRCA: smooth finish, cost-effective, powder coat friendly.

Galvanized steel (GI/GP): corrosion resistance under coating, good for outdoor cabinets and base structures.

Stainless steel: for harsh environments or premium exposed surfaces (as specified).

Aluminium: weight reduction where required.

Surface protection

Powder coating: durable finish options for indoor/outdoor deployment.

Plating / passivation: for internal brackets or specific corrosion requirements.

Sealing compatibility: coatings and surface prep must support gasket adhesion and long-term compression stability.

Material selection support: Share your environment (indoor/outdoor, coastal, chemical exposure, temperature range) and we’ll recommend a manufacturable, cost-optimized material stack-up.

Quality controls for battery enclosure programs

Dimensional control • sealing integrity • finish consistency.

Dimensional & fitment control

CNC manufacturing reduces variability across batches. Critical dimensions (sealing planes, hinge alignment, gland plates) are controlled through stable programs and inspection checkpoints.

Cosmetic & coating control

Coating consistency matters for outdoor deployments and brand-critical programs. We apply process discipline so colour/texture remain consistent over repeat runs.

Documentation: For OEM programs, we can support inspection formats as required (critical dimension lists, first-article checks, and repeat batch verification).

Frequently asked questions

Battery enclosure manufacturing queries.

Can Eterna manufacture IP-rated battery enclosures (including designs targeting IP68)?+

Yes. We manufacture battery enclosures with gasketed sealing features and construction methods designed around your target ingress protection. Achieving IP performance depends on complete system design (gasket, fasteners, cable entries, vents, flatness, and assembly control). We support engineering to make IP targets manufacturable and repeatable.

What information do you need to quote a battery enclosure?+

A drawing (2D/3D), target IP rating, installation environment (indoor/outdoor, coastal/industrial), material preference (CRCA/GI/SS/Al), finish requirement, quantity and annual volume, and any thermal/venting provisions (fans, filters, vents, heat exchangers). If you only have concept renders, we can still provide a feasibility-led estimate.

Can you support prototype builds and then scale to volume?+

Yes. We support prototype and pilot batches for field trials and scale to stable production using CNC processes and controlled work instructions. The goal is that what you approve in prototype is what you receive in volume, without quality drift.

Do you help optimize intricate or unusual enclosure profiles for manufacturability?+

Yes. Many battery enclosure designs include profiles that look “non-metal”. We review geometry for bend feasibility, tool clearance, weld access, sealing plane stability, and assembly practicality. We suggest alternatives that preserve performance and aesthetics while improving repeatability and cost.

Can you integrate mounting for busbars, trays, electronics and cable routing features?+

Yes. We manufacture internal bracketry, standoffs, gland plates, cable channels, partitions, and mounting points to suit your battery system architecture. Share your layout and we’ll incorporate manufacturable mounting features into the enclosure build.
