What are v mount batteries?

A v mount battery is a type of rechargeable and portable lithium-ion power source that usually features superior voltage, high density, and powerful output. They are capable of charging high-end devices like cameras, studio lights, wireless transmission systems, and so on. Therefore, they are popular among professional photographers. After all, most people don't need so much electricity, since they only need to buy a slim power bank, which is already enough to charge the mobile phone, tablet, or computer in a day of travel.

Two specifications to look at before using it

1. Watt hours

  • What is watt-hour and how to measure it

A Watt Hour is a unit of measurement for power over a period of time, generally measured by hour and related to the size, or in our case, a way of measuring capacity closely related to the v mount battery output. One Watts per hour is equal to one Watt of average power flow over an hour. One Watts over four hours would be four Watt Hours of power. As an example, a 100 Watt device on a 400 Watt Hour battery would last, on paper, 4 hours.

  • WH is related to whether it can be carried on the plane

There is a 100 WH carry-on restriction for lithium-ion batteries. Although v mount battery capacity up to 190 WH and beyond are available for purchase, you cannot take these on an airline. For compact one with greater capacity for 100 to 150 WH or more, there is a quantity restriction in which you can take up only two.

2. Current draw

  • Check the spec. sheet of your target devices before checking it

What is output current? Before getting to know how to use v mount battery, this is a measurement you should remember first. It is about how many amps a it can produce for a specified period of time. A 120 amp-hour type, for instance, can provide 12 amps of electricity for 10 hours before needing to be recharged. An amp-hour is a unit of time used to quantify the amount of current (in amps) flowing (an hour). This statistic reveals how many amps a gadget uses during an hour of use.

  • Pay attention to the current draw of your battery
  1. Moman Power 99 – 15A
  2. Moman Power 99S – 13A
  3. Moman Power 140 – 12A

Just like the calculation above, Amp hour=Amp*Discharge hour. And there’s also a calculator equation of Watt Hour=Amp hour* Voltages. Now with these product information and computing methods, you can easily calculate the charging capacity and how long does a v mount battery last. As a result, it's clear that the Power140 is better suited for high-powered devices such as studio lights, while the Power 99 and 99S are better suited for smaller devices such as camera lights and wireless monitors. Because if you use them to charge the same product like COLBOR CL60, it can be made to operate at full power for 1.2 hours with Power 99, and for around 1.8 hours using Power 140. But after all, the three are all powerful v-mounts that are suitable for power-hungry lights as well as those smaller things like cameras and monitors.

Use accessories to get tons of flexibility to use v mount batteries

Your needs are satisfactorily met by v-mount batteries. While you are recording, it has the capability to concurrently charge 200 Watts of numerous devices, such as director monitors, cameras, and LED studio lights. By using D-tap converters, it may also be used to power a wide range of devices, providing power to any item in the complete kit. How can it be possible, here are tools you might need to buy along with the compact v mount battery.

  • V mount battery plate or holder: If you want to add it to your photography setup, first you need the tools to attach it to your camera. Small plates are a good option, and sometimes they double as charging panels. The simplest solution at an affordable price would be to buy a small v lock and a hot shoe mount. Or you can buy a handheld grip with screw holes for installation.
  • Adapter or charger: You need to find the correct input ways and use the charging cable with the corresponding interface to charge the v mount battery. This is not difficult when you have to learn to control the charging time and method, which will greatly prolong its life and promote your working efficiency.

V mount battery vs gold mount, which is better? This is a common question. In some circumstances, you can even purchase adapters to change from v-mount to gold-mount. The v mount battery kit can be completed by adding these supplemental tools to assist you in your shooting activities. You don't have to be concerned about photos being cut short by a shortage of power thanks to the compact but strong power pack.

As the cell is charged and discharged, the available voltage inside it will gradually decrease. This is the consumption of its lasting life. All of the above three batteries have an output of more than 150W and even up to 200W, and the v mount battery voltage reached 14.4V and 14,8V, which are healthy and proved to be full-charged batteries. They can charge multiple devices simultaneously and are an excellent power solution for most high-drain devices. They all support various charging methods. Bmpcc cameras, DSLRs, mirrorless cameras, and other photographic devices with a d-tap input slot can be charged through the d-tap output interface, and the dummy battery via the power supply cable as well. Also, that includes high-power and high-output devices such as the studio light COLBOR CL100 with 100W constant power, which allows you to shoot for hours without a problem. The USB slots allow you to charge microphones, monitors and on-camera fill lights, and so on.

This habit can take a toll on itself. You need to know how to extend its life and how to use it. We advise maintaining batteries at 20–30% capacity when they won't be used for longer than a month. Make careful to check and maintain the charge level every few months. Here Moman also offers discounted bundles of v mount battery with charger for a variety of budget choices.

What should I pay attention to when storing batteries?

There are things you need to keep in mind when storing your battery. First, keep them away from sunshine and kids for avoiding accidents. Second, keep batteries high and secure places. Third, they should be kept dry and out of the way of jewelry and other metallic objects. They should also be kept in a non-conductive container. Batteries often keep their power for a long period if they are stored properly. Because of this, it's crucial to store anything you require. Remove the batteries from a gadget if you won't use a v mount battery for bmpcc 4k to power the supply for an extended length of time. The majority of gadgets do routine "checks" to make sure everything is still functioning as it should. Those checks need very little energy. Leakage might arise if they take place too regularly
