Trumony 48S Battery Pack Aluminum Box & Top Cover — In Stock and Ready to Ship
Trumony is pleased to introduce our newly designed battery pack housing — a matched aluminum box and top cover engineered specifically for the 48S battery pack configuration. With 200 units already in stock and no tooling or development fee required, this enclosure is an ideal drop-in solution for OEMs, pack integrators and e-mobility builders who need to move fast.
Product Overview
The housing measures 1060 × 616 × 120 mm and is manufactured using a combination of aluminum extrusion and friction stir welding (FSW). This process delivers a lightweight yet rigid structure with excellent sealing performance and thermal stability — critical requirements for modern lithium battery packs.
Although designed around a 48S cell arrangement, the enclosure is equally well suited to bus and coach applications, where large-format, high-capacity packs are required. Its robust construction and consistent dimensional accuracy make it a reliable choice for both passenger vehicles and commercial fleets.
Key Advantages
- Ready to ship: 200 units currently in stock for immediate delivery
- No mold or development fee: the design is already tooled and proven
- Lightweight construction: aluminum extrusion keeps weight low while maintaining strength
- Friction stir welded: leak-tight, high-strength joints with superior fatigue resistance
- Versatile fit: ideal for 48S battery packs and bus / coach battery systems
