What is the Canon 90D battery LP-E6N?
The Canon EOS 90D is a DSLR camera designed for enthusiasts, equipped with a 32.3MP sensor. It runs on the Canon LP-E6N, a rechargeable lithium-ion battery pack.
The LP-E6N delivers 7.2V and 1865mAh. It can be recharged through a standard power outlet using the Canon LC-E6 charger, which is sold separately. The battery measures 56*20*38mm, with a weight of 79g.
Battery life varies depending on the photographer’s shooting habits. Frequent use of the LCD screen for composing or reviewing images, for instance, will reduce overall performance.
The Camera & Imaging Products Association (CIPA) provides standardized testing guidelines for reporting camera battery life. Based on these standards, the Canon 90D is rated to capture approximately 1300 shots per charge. Since the CIPA test is fairly demanding, most users can expect to meet or exceed this number under normal conditions.
However, factors like cold weather, heavy LCD use, or frequent power cycling can lower battery life. Additionally, as the battery ages, its capacity and performance will gradually decline.

What is a V mount battery for Canon 90D camera?
A V-mount battery is a rechargeable lithium battery widely used in professional film and television production equipment. As the name suggests, it attaches to a battery plate using a V-shaped locking mechanism — with the male connector on the battery and the female connector on the plate.
V-mount batteries are known for their high capacity, strong power output, and quick-release design. They provide reliable power for professional cameras (such as ARRI and RED), film and TV lighting (like high-power LED panels), and other production gear.
Supporting hot-swappable operation, they are ideal for long shoots or demanding on-set environments. It is also a good option to use a V-mount battery for Canon 5D.
📌 Note: To use a V-Mount battery with the Canon 90D, you’ll need a DC coupler (dummy battery) that connects to your camera’s battery compartment, and a V-Mount plate with a D-Tap output.
⚙️ Key Specs:
Capacity: 50Wh–155Wh (sometimes up to 300Wh)
Voltage: 14.4V
Weight: 500g–1kg (depending on model)
Output ports: D-Tap, USB-C, USB-A, DC, etc.
✅ Advantages:
Massive capacity: Shoot for hours or even days without changing batteries.
Multi-device power: Run your camera and accessories from one source.
Professional workflow: Ideal for studio, filmmaking, and time-lapse setups.
❌ Limitations:
Heavier & bulkier: Not practical for run-and-gun photography.
Requires setup accessories: Plate, cable, and dummy battery.
Higher cost: The Initial investment is greater than buying spare LP-E6Ns.

Choose Canon LP-E6N if:
- You’re primarily shooting stills or short video clips.
- You want a lightweight, travel-friendly setup.
- You prefer Canon OEM compatibility and simple battery swaps.
Choose a V-mount battery for Canon 90D if:
- You film long sessions, such as interviews, documentaries, and live events.
- You use external monitors, microphones, or lights.
- You want continuous power without frequent battery changes.
Tips for choosing the right V-mount battery for Canon 90D if you want to buy one
If you decide a V-Mount setup suits your shooting style, here’s how to pick a V mount battery for DSLR like the Canon 90D:
Check the Battery Capacity for the preferred runtime of Canon 90D
This is the key specification—it indicates how much total energy the battery can store.
50Wh: A solid entry point, roughly equivalent to the power of two to three Canon LP-E6N batteries. It’s light, compact, and perfect for quick shoots or handheld, run-and-gun setups.
99Wh/100Wh: The ideal middle ground. This is the largest capacity allowed on most commercial flights without special approval. It delivers substantial power and is the most common option among professionals.
150Wh+: Best suited for intensive studio work or extended documentary filming in locations without access to mains power. These batteries are large and heavy, and air travel restrictions classify them as hazardous materials.
🎁 Recommendation: For most users, a 99Wh battery like Moman Power 99 Touch is the perfect balance of power, portability, and travel-friendliness. It features multiple output ports — D-Tap, USB-A, USB-C, and DC — allowing it to power various devices beyond your Canon 90D. The built-in LED screen makes it easy to monitor battery percentage and remaining charging time.
The Power 99 Touch is currently available under a “buy one, get the second at 50% off” deal. With 🎟️coupon code BATE20, you can get two units for just $232.70.
Consider the size and weight so the V-lock won’t throw off your 90D’s balance
The Canon 90D is relatively lightweight, weighing around 701g with the battery included.
Mounting a bulky V-mount battery on the back can affect the camera’s balance and handling, so it’s best to use a plate or adapter that keeps the setup stable and prevents it from becoming rear-heavy.
Take voltage and cable into consideration to avoid damaging the camera
V-mount batteries typically deliver a nominal output of about 14.4–14.8 V. To use one with the Canon 90D, your mounting plate or adapter must properly regulate this voltage, since the 90D operates on an LP-E6N battery rated at around 7.2 V. This means you’ll need a dummy battery, DC coupler, or voltage regulator that steps down the V-mount’s output to a safe level for the camera.
Ensure you’re using a dependable dummy LP-E6N battery or a mounting plate that provides the correct DC input for stable operation.
Check available output ports if you plan to power monitors, lights, or other devices
Since you’ll probably be powering additional gear like a monitor, wireless microphone, or LED light, choosing a V-mount battery with multiple output ports, such as D-Tap, USB-C, USB-A, and DC barrel, will make your setup more convenient.
Make sure the mounting plate delivers clean, stable power and properly regulated DC output for both the camera and any connected accessories.
Conclusion
For everyday photography, the Canon LP-E6N remains the most convenient and portable option. But if your work involves extended video recording, live streaming, or multi-device setups, a V-Mount battery system offers unmatched endurance and versatility.
When you balance cost, performance, and workflow, many 90D creators find that having both power options delivers the best of both worlds—lightweight when you need mobility, and powerful when you need longevity.
