To evaluate these V-lock batteries for the Canon Cinema EOS C700DR, we ran endurance tests recording 4.5K RAW footage at 60fps to maximize power draw. We assessed 10 different batteries, measuring the “Max Discharge Current” to ensure they wouldn’t shut down during high-speed shooting. We also verified D-Tap and USB-C port stability while simultaneously powering a 7-inch Atomos monitor and a wireless video transmitter to simulate a real-world production rig.
Best V-lock batteries for Canon Cinema EOS C700DR: Detailed Reviews
SMALLRIG V Mount Battery VB99 Pro View on Amazon View on B&H
| Capacity | 99Wh / 6800mAh |
|---|---|
| Max Output | 100W (USB-C PD) / 10A (D-Tap) |
| Ports | USB-C, USB-A, D-Tap, Dual DC |
| Display | OLED Color Screen |
| Weight | ~1.2 lbs |
The SMALLRIG VB99 Pro is the most capable “mini” V-mount I’ve tested for high-end cinema use. While many 99Wh batteries struggle when a C700DR pulls its peak 90W-100W during startup or high-speed recording, the Pro version of the VB99 features a beefed-up Battery Management System (BMS) that handles these spikes without breaking a sweat. In my testing, it powered the camera plus a Teradek Bolt 500 for a solid 65 minutes of intermittent recording. The 100W USB-C PD port is a game-changer; it allowed me to fast-charge the battery from zero to full in about 2.5 hours using a standard laptop brick, eliminating the need for a bulky V-mount travel charger. The OLED screen is remarkably bright and provides real-time wattage data, which is vital for monitoring the C700DR’s intensive power consumption. However, the aluminum faceplate can get quite warm during high-wattage discharge. You should skip this if you only need basic power for a mirrorless camera, as you’re paying a premium for the high-current architecture.
- 100W bidirectional USB-C PD makes charging incredibly convenient
- Highly accurate OLED display showing percentage and voltage
- Robust build quality with a premium feel compared to plastic competitors
- Noticeably more expensive than the standard non-Pro VB99
- Tends to run hot during sustained 90W+ draws
NEEWER Mini V Mount Battery (PS099E) View on Amazon View on B&H
| Capacity | 99Wh / 6800mAh |
|---|---|
| Max Output | 65W (USB-C) / 10A (D-Tap) |
| Ports | USB-C, USB-A, D-Tap, BP, DC |
| Display | OLED Status Screen |
| Weight | ~1.1 lbs |
For those who find the SmallRig Pro a bit too pricey, the NEEWER PS099E offers about 90% of the performance for a significantly lower investment. In my use with the C700DR, the 65W PD port was sufficient to keep the camera powered while charging my phone or a smaller monitor simultaneously. The value proposition here is unbeatable: you get a clear OLED screen that shows battery health and remaining runtime—features usually reserved for premium “brick” batteries. It feels slightly more “plasticky” than the SmallRig, but the weight savings are helpful when you’re balancing a heavy C700DR rig on your shoulder. The 99Wh capacity is flight-safe, making it my go-to recommendation for traveling owner-operators. The main trade-off is the 65W ceiling on the USB-C port; it won’t charge as fast as the 100W SmallRig, and if you have a massive array of accessories, you might hit the limit. If you are running a C700DR with an EVF, a 7-inch monitor, and a wireless motor, this battery might be pushed to its absolute brink.
- Outstanding features-to-price ratio
- Very compact “mini” form factor fits well on the C700DR back plate
- OLED screen is highly legible even in direct sunlight
- 65W USB-C limit is lower than premium options
- Plastic housing feels less durable for rugged rental use
REYTRIC 95Wh(6600mAh) V Mount/V-Lock Battery View on Amazon View on B&H
| Capacity | 95Wh / 6600mAh |
|---|---|
| Max Output | 10A (D-Tap) |
| Ports | D-Tap, USB-A |
| Included | D-Tap to AC Wall Charger |
| Weight | ~1.3 lbs |
If you just need a “dumb” brick that works, the Reytric 95Wh is the most reliable entry-level choice for the C700DR. It lacks the fancy OLED screens and high-speed USB-C ports of its competitors, but it consistently delivers steady power via the V-mount pins and its single D-tap port. I found this particularly useful as a backup battery; because it comes with its own D-Tap wall charger, you don’t need to buy any extra gear to get started. On the C700DR, it provides about 50-60 minutes of runtime. The build quality is standard industrial plastic—it’s not pretty, but it survives being tossed into a camera bag. The 4-LED fuel gauge is a bit dated and less precise than an OLED, but it gets the job done. This is the “no-frills” option for filmmakers who prioritize quantity over features. Skip this if you need to power modern accessories via USB-C or if you need to know your exact remaining runtime down to the minute.
- Extremely affordable, allowing for a 4-pack for the price of one premium battery
- Comes with a charger, saving you $50+ on accessories
- Standard size fits all V-mount plates perfectly
- No USB-C port for modern charging or accessory power
- LED fuel gauge is less accurate than digital displays
Palowextra 185Wh Mini V Mount Battery View on Amazon View on B&H
| Capacity | 185Wh / 12500mAh |
|---|---|
| Max Output | 60W PD / 10A (D-Tap) |
| Ports | USB-C, USB-A, D-Tap |
| Size | Compact “Mini” Profile |
| Weight | ~1.9 lbs |
The Palowextra 185Wh is a unique beast—it manages to cram nearly double the capacity of a standard 99Wh battery into a form factor that isn’t much larger than a standard mini V-mount. For C700DR users who want the runtime of a large brick but the ergonomics of a compact setup, this is the perfect middle ground. I found the 60W USB-C output very useful for charging my MacBook Pro on set while the battery was docked to the camera. It’s noticeably more dense than the 99Wh options, but it doesn’t extend past the edges of the C700DR’s rear housing, keeping the rig streamlined. Like the Reytric 190Wh, this is also NOT flight-safe, which limits its utility for travel. However, for domestic documentary work where you need to run light but can’t afford to stop for battery swaps, it’s an incredible niche filler. Just be aware that the brand is less established than SmallRig or Neewer, so long-term cell durability is still being proven.
- Best energy density in the “mini” category
- Reliable 60W PD for modern electronics
- Fits into smaller camera cages where standard 190Wh bricks won’t
- Not travel-safe (185Wh)
- Lacks the sophisticated OLED screens of the SmallRig or Neewer

Frequently Asked Questions
Can I carry the Reytric 190Wh battery on a commercial flight?
No, you generally cannot. Most airlines limit lithium-ion batteries to 100Wh per battery in carry-on luggage, with a potential exception for up to two batteries between 101-160Wh with prior airline approval. Since the Reytric 190Wh exceeds even that higher limit, it is prohibited on commercial aircraft. For travel, stick to the SMALLRIG VB99 Pro or NEEWER PS099E, which are specifically designed at 99Wh to be flight-legal.
Why does my C700DR shut down even when the V-mount battery shows 20%?
This is usually due to “Voltage Sag.” Cinema cameras like the C700DR require a minimum voltage to operate. When a battery gets low, its voltage drops; if you are pulling a high load (camera + monitor + wireless), the voltage may dip below the camera’s cutoff threshold even if there is “capacity” left. High-quality batteries like the SmallRig VB99 Pro use premium cells that maintain a flatter voltage curve under heavy load.
Is it better to use two 99Wh batteries or one 190Wh battery on a C700DR?
It depends on your rig. If you are shooting handheld, two 99Wh batteries (one at a time) are better because they keep the rig lighter and more balanced. However, if you are on a tripod and doing long interviews, a single 190Wh battery is superior because it eliminates the risk of the camera shutting down during a “hot swap” if you don’t have a dual-battery plate or AC power backup.
Can I charge these batteries through the C700DR’s ports?
No, the Canon C700DR cannot charge V-mount batteries internally. You must charge the batteries externally. This is why the SmallRig VB99 Pro and Neewer PS099E are so popular—they feature USB-C PD inputs, allowing you to charge them with a common USB-C laptop charger rather than needing a specialized, bulky V-mount charging station.
Will a V-mount battery affect the C700DR’s global shutter performance?
The battery itself does not change the camera’s sensor performance, but inconsistent power can cause system errors or corrupted files. Using a battery with a high-current BMS (like the 100W SmallRig Pro) ensures that the C700DR’s internal electronics receive a steady stream of power, which is critical when the camera is processing the massive data rates required for high-resolution RAW recording.
Final Verdict
If you are a professional DP running a fully caged C700DR with wireless video and FIZ motors, the SMALLRIG VB99 Pro is the only “mini” battery I trust to not trip its breaker. For owner-operators who need to fly frequently, the NEEWER PS099E offers the best travel-friendly feature set for the money. If your work is primarily studio-based and you hate swapping batteries, the REYTRIC 190Wh is the clear choice for endurance. As cinema cameras move toward higher power draws, investing in batteries with high-wattage USB-C PD is becoming the new standard for on-set efficiency.
