Best V-Mount Batteries for Canon Cinema EOS C70: Detailed Reviews
Core SWX Nano Micro 98 View on Amazon View on B&H
The Core SWX Nano Micro 98 is the industry standard for a reason. When I rig my C70, I want a battery that doesn’t dwarf the camera’s compact form factor, and the Nano Micro fits like a glove. With a 98Wh capacity, it is flight-safe and provides enough juice to power the C70 and a high-bright monitor for hours. Its 12A load capacity is impressive, ensuring that even if you’re running a wireless follow focus and a transmitter simultaneously, you won’t experience power sag. The build quality feels incredibly rugged, designed to survive the rigors of a professional set. It features a P-Tap and a USB port, providing just enough connectivity without becoming bulky. While it lacks the fancy OLED screens of some competitors, its four-stage LED gauge is accurate and dependable. It’s the “set it and forget it” choice for working pros.

SmallRig VB99 Pro View on Amazon View on B&H
SmallRig has absolutely disrupted the battery market with the VB99 Pro. If you’re like me and hate carrying a massive dedicated V-mount charger, this is your savior. The built-in 100W USB-C bidirectional PD port means you can charge this battery with your MacBook brick or even a high-speed phone charger. On the C70, this battery is a dream because it can power the camera via the USB-C port or a D-Tap to DC cable. The OLED screen is a game-changer, showing you exactly how much time is remaining based on your current power draw. It’s remarkably compact, roughly the size of a deck of cards. The only minor drawback is that the plastic housing doesn’t feel quite as “bomb-proof” as the Core SWX, but for the price and the sheer number of ports (USB-A, USB-C, D-Tap, DC), the value is unbeatable.

ZGCINE V99 View on Amazon View on B&H
The ZGCINE V99 is currently one of the most affordable ways to get into the V-mount ecosystem without buying “no-name” junk. It provides 99Wh of capacity, hitting that sweet spot for travel compliance while offering enough power for a half-day of shooting on the C70. What I appreciate about this budget option is that it doesn’t skimp on the modern essentials; you still get a USB-C PD output and a D-Tap. In my testing, the power delivery is stable, though the battery does tend to get a bit warmer than the premium options during heavy use. The aesthetics are a bit “flashy” with the orange accents, which might not suit every professional rig, and the build is noticeably more “plasticky.” However, if you’re building out your first C70 rig and need to save cash for lenses, the V99 is a reliable workhorse that won’t let you down.

Anton Bauer Titon Micro 90 View on Amazon View on B&H
Anton Bauer is a name synonymous with high-end broadcast power, and the Titon Micro 90 brings that pedigree to the Canon C70. The standout feature here is the precision of the LCD screen. Unlike cheaper models, the Titon calculates the draw of your specific rig in real-time, telling you down to the minute how much runtime you have left. This is invaluable when you’re 10 hours into a shoot and need to know if you can squeeze one last take. The 10A continuous draw is robust enough for any accessory package. It’s built like a tank and uses high-quality cells that hold their capacity over hundreds of charge cycles. While it is more expensive than the SmallRig or ZGCINE, you are paying for the peace of mind that only a premium brand can offer. If your C70 is earning you a living on commercial sets, this is the investment to make.

FXLION NANO TWO View on Amazon View on B&H
The FXLION NANO TWO was one of the first “micro” V-mounts to hit the market, and it remains a favorite for its versatility. It offers a 98Wh capacity in a footprint that is surprisingly small—you can literally fit it in a jacket pocket. What makes it special for the C70 is the variety of outputs: D-Tap, USB-A, and USB-C. This allows you to power the camera while also keeping your phone or a wireless transmitter charged without needing a complex distribution box. I find the LCD screen clear and easy to read, even in bright sunlight. The build quality is solid, sitting somewhere between the SmallRig and the Core SWX. It’s an “Also Great” because it doesn’t quite have the fast PD charging speeds of the SmallRig Pro, but its long track record of reliability makes it a very safe bet for any filmmaker.

Frequently Asked Questions
Do I need a special plate to use V-mount batteries on the C70?
Yes, the Canon C70 does not have a native V-mount. You will need a V-mount battery plate that either mounts to your camera cage or fits directly into the BP-A battery slot. Popular options include the Kondor Blue Cine V-Mount Plate or the Tilta V-Mount Battery Baseplate. These plates usually provide a D-Tap output that connects to the C70’s DC input via a specialized cable, allowing the battery to power the camera body.
Can I travel on an airplane with these V-mount batteries?
Generally, yes, as long as the capacity is under 100Wh. All the batteries on this list (90Wh to 99Wh) are designed to be “flight-safe.” However, you must keep them in your carry-on luggage; lithium-ion batteries are strictly prohibited in checked bags. It is always wise to tape over the terminals or keep them in individual pouches to prevent short circuits. Check with your specific airline, as some have limits on the total number of batteries allowed.
How long will a 98Wh V-mount battery power the Canon C70?
The Canon C70 is remarkably power-efficient for a cinema camera, drawing approximately 15-20W during standard operation. A 98Wh battery will typically power the camera body alone for about 5 to 6 hours. If you are also powering a high-brightness monitor (like a SmallHD Ultra 5) and a wireless transmitter, your runtime will drop to around 3 to 4 hours. Having at least two 98Wh batteries is usually sufficient for a standard shooting day.
Can I charge these batteries via USB-C?
Only certain models, like the SmallRig VB99 Pro and FXLION NANO TWO, support direct charging via USB-C Power Delivery (PD). This is a massive advantage for travel, as it eliminates the need for a bulky V-mount charger. For batteries like the Core SWX or Anton Bauer, you will typically need a dedicated V-mount charger or a D-Tap “travel” charger. Always check if the USB-C port is “bidirectional” before assuming it can be used for charging the battery.
Will a V-mount battery make my C70 rig too heavy?
Adding a V-mount battery will certainly increase the weight of your rig, often by 1 to 2 pounds including the mounting plate. However, for many users, this extra weight is actually beneficial. It helps stabilize handheld shots by adding inertia, reducing micro-jitters. Furthermore, by mounting the battery at the rear of the camera on rods, you can create a better balance point, making the camera feel lighter on your shoulder or when using a top handle.
Final Verdict
For professional shooters who need absolute reliability, the Core SWX Nano Micro is the clear winner. If you are a solo content creator or travel frequently, the SmallRig VB99 Pro’s USB-C charging makes it the most convenient option. Budget-conscious filmmakers will find the ZGCINE V99 to be a capable companion that leaves more room in the gear bag for other essentials. No matter your choice, moving to V-mount will transform your C70 into a truly unstoppable production tool.
