It’s not often one of a videographer's favorite gigs to take on, but long-duration and high-intensity video work can pay the bills. The catch: it can be tricky for several reasons. Focus issues, as well as mental and physical constraints, can make it difficult. And there are also technical concerns.
One of the biggest challenges with long-duration video recording is power. Space is an issue too, but has its own set of solutions. To tackle the power side, you’ll either need direct access to a power source and outlet, or a battery designed to handle these specific demands.
And that’s what this new T221 Triple-Proof IP54 Waterproof V-Mount Battery from SmallRig aims to offer. Let’s check it out.

So, what’s unique about this new V-Mount Battery from SmallRig is that it has a triple-proof design that should make it about as durable as any on the market. It will feature an IP54 rating that makes it waterproof and dustproof, while the housing is drop-resistant up to 5.9'.
It will also provide plenty of power with a 14.8V, 221Wh, 15,000mAh rated capacity and multiple ports to power various accessories. These power options will also offer overcurrent, overvoltage, and over-charging/discharging protection.
It should also be versatile and easy to use, thanks to its independent circuits, which let users use one USB-A, one DC barrel, two USB-C, and four D-Tap ports to power and charge multiple devices at once.
