The Smart Box by VMAX USA is a commercial-grade and heavy-duty battery box designed for marine, back-up, automotive, construction, off-grid power supplies, and other applications. The vented boxes are water-resistant and protect against water splashes, but they are not waterproof if submerged in water.

It fits all traditional U1 battery group sizes as well as new orbital or spiral celled, deep cycle, AGM, WET, LITHIUM, and high-performance batteries. The QuickLock Cover makes it easy to put on and take off, ensuring the box is secure and prevents cover loss. It can be used with hold-down holes molded into reinforced handles, J-hooks, L-hooks, threaded rods, or lag bolts. The new tougher material is impact-resistant to -30°F (-34°C) and heat-stable to +200°F (+93°C).
