SmallRig 4985 X-Touch Smart Triple-Proof V-Mount Battery X221

The SmallRig X-Touch Smart Triple-Proof V-Mount Battery X221 (4985) sets a new benchmark for professional on-set power by combining smart technology, rugged construction, high-power fast charging, and multi-port versatility. Engineered for demanding shooting environments, it delivers reliable, intelligent, and durable power performance for filmmakers who require absolute confidence in their gear.

Built to withstand the rigors of professional production, the X221 features triple-proof protection, including a 1.5m (4.9ft) drop-resistant housing, eight silicone-reinforced corners, silicone-covered metal panels, and fully protected internal circuitry. With an IP54 waterproof and dustproof rating, it ensures dependable operation in rain, splashes, dust, and challenging outdoor conditions.

The X221 offers eight strategically arranged output ports—one BP port, two D-Tap ports, two USB-C ports (supporting 140W PD fast charging), one USB-A port, and two DC outputs. Each port is built with an independent circuit, enabling multiple high-draw devices to be powered simultaneously without interference or overload. The battery also supports fast self-charging in just 2.5 hours, ensuring minimal downtime on set.

At the heart of the system is a 2.0-inch HD color touchscreen with a frosted anti-glare finish for excellent visibility in all lighting conditions. Workflow efficiency is further enhanced by the dedicated mobile app, which provides remote monitoring and control—including real-time power status, port management, battery location tracking, and OTA firmware updates.

Powered by premium LG lithium-ion cells and advanced BMS smart chips, the X221 delivers robust eight-layer protection, safeguarding against over-current, over-temperature, over-load, and other critical risks. With highly accurate power-level indication and long cycle life, users can operate with complete confidence and peace of mind.

For mounting flexibility, the battery includes 1/4"-20 and 3/8"-16 threaded holes, along with a rear backlight indicator for fast and precise installation even in low-light environments. These professional-grade features make the X221 a dependable, all-weather power solution—allowing creators to focus entirely on production without worrying about power stability.
