The Smart Box by VMAX USA is a commercial-grade product designed for heavy-duty marine, back-up, automotive, off-grid power supplies, construction, and other applications. The adjustable Group 24, 27, and 31 Smart Battery Box features a digital LED voltmeter display and dual USB-C + 1 USB ports, along with wires with ring ends, a mounting strap, and brackets. It is suitable for all traditional battery group sizes, as well as new orbital or spiral-celled, deep-cycle, high-performance batteries.

The QuickLock cover is easy to use, providing a safe and secure solution. The convenient, fast, and durable design prevents cover loss, and the hold-down holes molded into the reinforced handles allow for the use of J-hooks, L-hooks, threaded rod, or lag bolts. Users can remove the lid while keeping the box secure.

The new tougher material used in the Smart Box is impact-resistant to -30°F (-34°C) and heat-stable up to +200°F (+93°C), meeting the U.S. Coast Guard Regulations 183.420 and ABYCE-10.7. The box is impervious to acid, gasoline, oil, and solvents, and it will not rust or be affected by UV exposure. It is proudly made in the USA.

The inside dimensions of the Smart Box are 14-1/2"L x 7-1/4"W x 10-3/8"H, and the outside dimensions are 17-3/4"L x 10-1/4"W x 10-7/8"H. The vented boxes are water-resistant, protecting against water splashes, but they are not waterproof if submerged in water.

With its versatile design, durability, and user-friendly features, the Smart Box by VMAX USA is an ideal solution for a wide range of power supply applications, from marine to automotive to off-grid use.
