What V-mount means
V-mount describes the mount: a V-shaped mount that locks a battery onto a camera rig, so the battery stays in place during a shoot. The mount matters because a broadcast rig moves, and a battery that slips will cut power to the camera and its accessories, interrupting the shoot. A V-mount battery is chosen for its mount first, then for its energy and outputs, because a battery that does not mount cannot serve, however good its energy.
V-mount batteries are broadcast batteries, used on professional camera rigs rather than on consumer cameras, and they power not just the camera but also its accessories, such as monitors, lights, and wireless transmitters. That role explains their size and energy: a broadcast battery must power several devices for hours, not just one camera for a short time.
Energy: 207Wh against 99Wh
Energy describes how long a battery can power a rig, and the two V-mount models on this site differ in energy: 207Wh against 99Wh. A rig that runs for hours, powering a camera and several accessories, needs more energy than a rig that runs for a short shoot, and the 207Wh model suits the former while the 99Wh model suits the latter, where weight matters more than duration.
Energy alone does not decide the choice, because outputs matter too: the 207Wh model states Dual D-Tap plus USB plus Type-C outputs, so it can power several accessories at once, while a rig with few accessories may not need those outputs. Check the model pages' outputs against the rig's accessories, and confirm in the inquiry.
Voltage and PD
Voltage describes the battery's electrical level, and both V-mount models on this site state 14.4V, so voltage does not distinguish them. PD describes power delivery, a way of delivering power over USB-C, and both models state PD 65W, so PD does not distinguish them either. The choice between them is about energy and weight, not about voltage or PD, and a buyer who chooses by voltage alone will find both models match.
A rig's voltage requirements should still be checked, because a battery with the wrong voltage will not serve a rig, however well it mounts or however much energy it holds. Check the model page's voltage against the rig's requirements, and confirm in the inquiry, naming the rig and its accessories.
Temperature ranges
Both V-mount models state operating, discharge and storage temperature ranges, because broadcast rigs work outdoors as well as in studios, and a battery used outside its stated ranges may not perform as expected. A rig that works in cold or heat should check the ranges against its conditions, and a rig that works in extreme conditions should ask whether a different battery suits it better.
Do not assume a temperature range for a model that does not state one, and do not assume one model's range applies to another, because ranges are stated per model. Ask in the inquiry, and check the answer against the model page, so the battery's ranges are known before ordering.
Cells and weight
Cells describe how many individual cells a battery contains, and the two V-mount models differ in cell count: 16 cells against 8 cells. More cells mean more energy, but also more weight, and the choice between them is a trade-off between duration and weight, as with any battery. A rig that is carried for hours will feel the weight of a larger battery, while a rig on a tripod may not.
Weight matters for broadcast work, because a rig is carried, held, or balanced, and a heavier battery changes the rig's balance. A buyer should weigh the energy against the weight, and should consider the rig's total weight, including camera, accessories, and battery, rather than the battery alone.
Charging V-mount batteries
V-mount batteries are charged with V-mount chargers, such as the four-slot charger on this site, which charges four V-mount batteries, with charging current falling as more slots are filled. A broadcast team with several V-mount batteries should plan charging as part of its workflow, with enough chargers and slots for its batteries, rather than as an afterthought, because a rig without a charged battery cannot shoot.
Charge V-mount batteries in a ventilated place, where charging batteries can be watched, and do not leave them unattended for long periods, especially overnight or in a hot place. These are general terms, and the battery's and the charger's own documentation should be followed where they differ.
Common mistakes
A common mistake is choosing a V-mount battery by energy alone, without checking its outputs, so a rig with many accessories finds its battery cannot power them all. Another is choosing by weight alone, without checking energy, so a rig runs out of power mid-shoot. A third is assuming a V-mount battery serves any V-mount rig, without checking the rig's voltage and accessory requirements, so a battery that mounts well still does not serve.
All three mistakes are avoided by the same step: check the model page's specification table against the rig and its accessories, and confirm in the inquiry, naming the rig and its accessories, before ordering. The confirmation takes a few minutes, and it prevents a costly mistake.
Before you order a V-mount battery
Name the model, the exact broadcast camera and accessories it must power, the quantity you have in mind, and the market you sell into, in the inquiry. Ask for the specification for the exact model, the minimum order quantity, the lead time with its meaning, the warranty terms, and the certificates that apply to your market, by name, with documents attached. Do not pay before these have been confirmed for the exact models in the order.
A V-mount battery is only as good as its match to the rig, and the match is only as good as the confirmation. The V-mount guide explains the choice in general terms, and the V-mount model pages give the per-model specifications.
A note on sources and confirmation
The model specifications and compatibility statements referred to in this article come from the company profile's official product pages, as presented on this site's model and category pages. Compatibility statements are the company profile's own statements, quoted with attribution, and they are not statements by the equipment makers, nor do they imply authorisation, endorsement, or original manufacture. A specification stated for one model is not carried to another model, and a figure stated for one model should not be assumed for any other.
Figures that are not stated on a model page — a price, a minimum order quantity, a lead time, a warranty period, or a certificate for a specific model and market — are confirmed per order in the inquiry, and this article does not invent them. A buyer who needs any of those should ask for it by name, for the exact model and the exact equipment variant it must serve, with documents attached where documents are what is needed, so the answer is specific rather than general.
Before ordering, name the model, the exact equipment variant it must serve, the quantity you have in mind, and the market you sell into, in the inquiry. Ask for the specification for the exact model, the minimum order quantity, the lead time with its meaning, the warranty terms, and the certificates that apply to your market, by name, with documents attached. Do not pay before these have been confirmed for the exact models in the order, because payment removes the leverage to resolve an unconfirmed item, and a confirmed order is the only basis for a safe purchase.
