Why Aluminum for Battery Enclosures
Five engineering reasons 2W/3W OEMs choose aluminum — extrusion, CNC & anodizing, one integrated production network
Lightweight = Longer Range
Aluminum is 2.7 g/cm³ vs steel 7.8 g/cm³ — up to 50% lighter at equal strength. Less dead weight means longer range per charge or more passengers carried — the #1 buying factor for Indian e-rickshaw and e-scooter operators.
Read more →Thermal Management for Battery Safety
With summer temperatures regularly above 40°C, heat is the #1 threat to 2W/3W battery packs. Aluminum’s high thermal conductivity pulls heat away from cells, reducing thermal runaway risk and extending battery life.
Read more →Built for Monsoon & Salt Spray
India’s monsoon rains, flooded streets and coastal humidity destroy steel housings within months. Anodized aluminum resists corrosion, rust and peeling paint — year after year.
Read more →IP65 / IP67 Sealing
Dust and water ingress are deal-breakers for battery enclosures. Our extrusion, CNC machining and gasket assembly achieve IP65/IP67 sealing to keep cells dry through puddles, dust and heavy rain.
Read more →Crash & Vibration Resistance
Potholes, speed bumps and rough roads are everyday reality for Indian 2W/3W vehicles. One-piece extruded enclosures absorb shock far better than welded sheet metal — no weld seams to crack, no rattling joints.

Applications
Battery Enclosure Applications
Engineered aluminum housings for two & three-wheeler EV platforms — from city scooters to heavy-duty auto rickshaws.
Electric Two-Wheelers
Slim extruded enclosures that drop straight into the scooter's under-floor frame — lightweight, crash-resistant, and sealed for daily riding.
- Low-profile sections for under-seat and floor-mounted packs
- 6063-T5 / 6061-T6 alloys, wall thickness from 1.5 mm
- Anodized finish for corrosion resistance
Electric Three-Wheelers
Heavy-gauge housings engineered for e-rickshaw duty cycles — rough-road vibration, monsoon humidity, and high-capacity battery packs.
- Reinforced mounting brackets for vibration loads
- Large cross-sections for 100 kg+ battery packs
- Sealing options up to IP67
Custom Battery Housings
Send your CAD file or battery module dimensions — we engineer the enclosure around your pack, from profile design to finished assembly.
- From drawings to extrusion die in 2–3 weeks
- CNC-machined interfaces, busbar cutouts & thermal channels
- Pilot runs at MOQ-friendly quantities
Structural Integration
How the Enclosure Fits Your Vehicle
