SmallRig X221 V-Mount Battery 221Wh 4985

Description

Is the SmallRig X221 the right battery for your production?

✅ Outdoor operators in adverse weather conditions

The SmallRig X221 (4985) is the only V-Mount battery in the SmallRig catalog with IP54 certification and validated drop resistance from 1.5 meters . Its casing combines fire-retardant polycarbonate, shock-absorbing silicone at eight corners, and aluminum alloy side panels with fully sealed internal gaskets. For outdoor shoots in rain, dust, or other extreme conditions where a conventional battery would pose a risk of failure, the X221 offers the most reliable power available in its capacity range.

✅ Productions in extreme cold: mountains, winter, surveillance cameras

The graphene heating technology integrated into the X221 solves the most common problem with lithium batteries in winter outdoor environments: drastic capacity loss and the inability to fast charge below 0°C. The X221 maintains a full 140W charge even at -15°C , while discharging operates within a range of -15°C to 55°C . For crews filming in alpine conditions, winter reportage, or outdoor installations in sub-zero temperatures, this feature is a decisive advantage that no standard V-Mount battery can match.

✅ Complex rigs with multiple simultaneous devices

The X221's eight ports with independent circuitry allow you to simultaneously power up to eight devices without the load of one affecting the speed or stability of the others: a cinema camera via BP or D-Tap, a monitor via D-Tap or DC, LED lights via DC, wireless transmission via USB-C or USB-A, and smartphone charging via USB-A. The maximum output power reaches a total of 221W , with a maximum of 15A through the BP and D-Tap ports . For productions with complex camera rigs where power management is a critical workflow point, the X221 centralizes all power without compromising any device.

⚠️ When to evaluate the SmallRig VB99 Pro Mini (4292)

If weight and size are priorities over maximum capacity or IP protection, the SmallRig VB99 Pro Mini (4292) offers 99Wh in 70% the size of a standard V-Mount, with 100W bidirectional charging and direct BP output without an additional board. For single-carrier run-and-gun setups, the VB99 Pro Mini is the lighter and more practical option. Both are available at Galaxy Andorra .

SmallRig X221 — Triple-Proof technology and professional power hub

The SmallRig X221 (4985) combines three technologies typically required separate for professional production into a single unit: a high-capacity V-Mount battery, a multi-device power hub, and an intelligent management system with remote control. Its 221Wh capacity, featuring automotive-grade LG cells (12 x 5,000mAh cells), guarantees superior energy density and cycle life stability compared to most V-Mount batteries on the market. The integrated BMS chip with PowerADC technology—which combines the control circuitry, current management, and cooling system into a single component—provides eight layers of protection: overcurrent, overtemperature, overcharge, short circuit, over-discharge, reverse polarity, overcharge, and individual cell protection.

X-Touch touchscreen and SmallGoGo app — total control of feeding

The 2-inch X-Touch touchscreen with anti-glare coating and scratch-resistant frosted surface displays real-time charge level, voltage, battery temperature, the status of each port, and estimated charge/discharge time. Unlike the static display screens of other V-Mount batteries, the X221's screen is touch-sensitive and allows you to activate or deactivate individual ports directly from the battery without accessing the app.

The SmallGoGo app (iOS and Android) extends control up to 10 meters via Bluetooth and adds battery location features on set, OTA firmware update management, and charge cycle history monitoring. In productions with multiple camera rigs and batteries on set, the location feature allows each battery to be identified without physical labeling.

Expert opinion of Galaxy Andorra

At Galaxy Andorra, we want to highlight the X221's ability to charge at full 140W at -15°C, a feature that is particularly underrated for operators at latitudes or altitudes with harsh winters. Most V-Mount batteries on the market drastically reduce their charging speed below 5°C, and some even stop charging altogether below 0°C—the X221 eliminates this risk with active graphene heating. In mountainous or outdoor winter shoots, where time between charges is critical, this guaranteed fast charging in cold conditions represents a crucial operational advantage that competing models don't offer at this capacity. Available at Galaxy Andorra , with official SmallRig warranty and shipping to Spain, France, and Portugal.

Frequently Asked Questions about the SmallRig X221 (4985)

What does the IP54 certification of the SmallRig X221 mean?

The IP54 rating indicates that the SmallRig X221 (4985) is protected against dust (level 5 — no harmful dust buildup inside) and against water splashes from any direction (level 4). In practical terms, it functions normally in light rain, in dusty or sandy environments, and can withstand accidental liquid splashes. It is not designed for immersion in water. For outdoor production in varying weather conditions, the IP54 rating provides reliable, professional-grade operational protection.

How does charging at -15°C work with graphene technology?

Conventional lithium batteries drastically reduce their charging rate or disable it entirely below 0°C to protect the cells. The SmallRig X221 (4985) incorporates a graphene active heating system that preheats the cells internally when the ambient temperature drops below the safe charging threshold, maintaining full 140W charging capacity down to -15°C . The discharge temperature (cold run) is also -15°C, covering all winter outdoor shooting scenarios in Europe.

Is the SmallRig X221 compatible with the V-Mount standard of other brands?

Yes. The SmallRig X221 (4985) uses the standard V- Mount (also called V-Lock), compatible with V-Mount plates from any manufacturer and with video cameras and rigs that support this standard. In addition to the V-Mount, it features 1/4"-20 and 3/8"-16 threads for mounting rig accessories and a backlit LED indicator for easy setup in low-light conditions.

How many devices can the SmallRig X221 power simultaneously?

The SmallRig X221 (4985) features eight ports with independent circuitry : two USB-C (140W each), one USB-A (30W), one Power Bank (15A), two D-Tap (15A and 10A respectively), one 8V DC (3A), and one 12V DC (3A). Because they operate with independent circuitry, charging or powering one device does not affect the speed or stability of the others. The maximum total output power is 221W . In practice, this allows you to simultaneously power a cinema camera, a monitor, an LED light, a wireless transmitter, and charge the operator's smartphone from a single battery.

What is the difference between the SmallRig X221 (4985) and the VB99 Pro Mini (4292)?

The main differences are capacity— 221Wh vs. 99Wh —protection—the X221 has IP54 certification and 1.5m drop resistance compared to the standard VB99 Pro Mini—and the number of ports— 8 ports vs. the multiple ports of the VB99 Pro Mini . The VB99 Pro Mini (4292) has the advantage of incorporating a direct BP output without a V-Mount plate and is significantly more compact and lightweight. The choice depends on the production profile: the X221 for professional sets with multiple devices and demanding conditions, the VB99 Pro Mini for compact run-and-gun rigs. Both are available at Galaxy Andorra .
