Power Battery Outer Cover OE 2120332-TE821 for Dongfeng New Energy | Genuine Truck Part

This power battery outer cover OE 2120332-TE821 is manufactured strictly to Dongfeng New Energy original design specifications, using high-strength steel that offers exceptional rigidity, impact resistance and anti-deformation performance. The surface is coated with a thick black anti-corrosion layer that resists oxidation, road salt, moisture and dust erosion, ensuring long-term structural stability and appearance integrity. The internal side features pre-installed shock-absorbing and anti-slip strips, which reduce vibration transmission between the cover and the battery pack, preventing wear and noise. It adopts a 1:1 original size and contour design, with precisely positioned mounting holes that perfectly match the truck’s chassis and battery pack fixing points, ensuring a tight, gap-free fit and stable fixation. The reinforced edge structure effectively absorbs impact and vibration from bumpy roads, firmly protecting the battery pack and preventing deformation or damage. It is specially engineered for heavy-duty new energy truck operation with strong durability and reliability.

Fully compatible with all applicable Dongfeng New Energy truck models, this battery outer cover can be quickly verified via OE 2120332-TE821 to ensure accurate matching. It solves multiple common failures caused by low-quality aftermarket covers, including thin material that bends and deforms easily, rough processing leading to mismatched holes, poor anti-corrosion performance causing early rust and fracture, and insufficient protection leading to battery pack exposure and impact damage. Exposed battery packs are vulnerable to road debris, water splashes and corrosion, which can lead to short circuits, insulation failure and even safety hazards. By installing this genuine cover, users can eliminate battery exposure, impact damage, corrosion and frequent replacement troubles, effectively protecting the high-voltage battery pack and improving driving safety.

As a key safety component for new energy vehicles, this power battery outer cover meets Q/DFL 6020-2021 Dongfeng automotive parts quality standards and has passed authoritative third-party tests for impact resistance, vibration fatigue and corrosion protection. Test data shows the product remains free of deformation, cracks and coating peeling after long-term high-vibration and high-impact testing, and maintains stable structural strength in extreme temperature cycles. Each cover undergoes full dimensional inspection, mounting hole calibration, shock-absorbing strip adhesion and coating quality verification before shipment, ensuring complete consistency with original factory parts in size, strength, radian and installation effect. It performs reliably on muddy roads, construction sites, rural roads and coastal areas, with strong resistance to wear, rust and deformation. Backed by complete factory traceability and quality certification, it provides users with long-term, trustworthy protection performance.
