Metal Box (340X360X295mm) for ESS Highstar 8 Cell Screw Wall Mount

METAL BOX ESS W/M 8CELL HIGHSTAR (340X360X295mm)

The METAL BOX ESS W/M 8CELL HIGHSTAR (340X360X295mm) is a metal battery enclosure intended for energy-storage builds using an eight-cell Highstar prismatic-cell layout. The listed external size is 340 x 360 x 295 mm, providing a defined mechanical envelope for battery builders planning an ESS, inverter or backup-power assembly. A purpose-made metal enclosure helps organize cells, busbars, BMS components, wiring and external terminals while providing mechanical protection around the battery module.

The enclosure should be treated as a mechanical platform rather than proof of electrical compatibility. The phrase ""8CELL HIGHSTAR"" identifies the intended cell family/layout, but prismatic cells can vary in terminal position, compression requirement and accessory arrangement even within the same brand. The internal cell tray, busbar spacing, BMS mounting and cable exits of the current stock box should therefore be checked against the actual cells before production assembly.

The verified catalog dimensions are 340 mm x 360 mm x 295 mm and the enclosure is listed for an eight-cell Highstar ESS configuration. Metal construction provides rigidity and impact resistance compared with a flexible outer wrap, but it also creates a conductive enclosure that must be electrically isolated from live cell terminals, busbars and cable lugs. Internal insulation sheets, terminal boots, cable glands, grommets and properly routed conductors are essential parts of a safe finished battery.

Prismatic cells can expand slightly during service and many pack designs use controlled compression. The enclosure should not be used to force cells into an incompatible space. Allowances are also required for the BMS, fuse, service disconnect, busbars, terminal studs, display or communication ports if used. Thermal design should prevent hot components from being trapped without adequate spacing or airflow.

Confirm the actual Highstar cell dimensions, terminal orientation and number of cells before ordering. Measure the complete cell stack including insulating separators and compression plates, then compare it with the usable internal dimensions rather than only the outside size. Verify whether the ""W/M"" stock version includes mounting hardware, a wall-mount arrangement, internal brackets or other accessories before relying on those features in a system drawing. Also check door/lid clearance, external terminal cutouts and BMS mounting position.

Applications

• Eight-cell Highstar prismatic battery modules for compatible ESS projects.

• Inverter and backup-power battery enclosures.

• Solar-energy storage and small commercial ESS assemblies.

• Battery workshops building organized metal-cased prismatic packs.

• OEM prototypes requiring a 340 x 360 x 295 mm enclosure envelope.

Installation Guide

Fit non-conductive insulation between cells and all metal enclosure surfaces. Secure cells according to the cell manufacturer's mechanical guidance, route high-current conductors away from sharp edges and use grommets or glands at every cable exit. Protect exposed busbars and terminal studs against accidental contact. Bond or earth the enclosure only where the complete system design requires it, keeping the battery's live conductors isolated from the case. Before closing the enclosure, verify polarity, insulation resistance where appropriate, mechanical clearances and secure mounting of all components.
