Easiest Way To Discharge DJI Drone Batteries Before A Flight Or Storage

Published

on

One nice feature of DJI intelligent drone batteries is the fact that they will self-discharge after a predetermined amount of time that can be set via the DJI Go 4 app. Storing a lipo battery at full charge can damage it over time and that is why DJI included this feature in it intelligent drone batteries. The discharge, however, can take several days and what if you have a last minute flight and you need to discharge your batteries quickly. Some airline around the world requires lipo batteries be drained before you enter the aircraft. Personally, I have never been asked to show my batteries are discharged before a flight but I do know of people who have been asked to show every battery. It’s better to be safe than sorry when traveling on a plane to avoid any unwanted hassle.

My method of discharging DJI Drone batteries such as the Mavic Air, Mavic Pro, Mavic 2 Pro/Zoom and the Phantom 4 Series is to use the Battery to power bank adapter. This adapter is included in the fly more kits for each drone and can also be purchased separately. The adapter essentially turns your drone battery into a power bank that can be used to charge devices such as smartphone and tablets. To discharge your DJI Drone battery quickly simple fit the adapter on your battery and charge up any devices that needs charging. Your drone batteries will be quickly and safely discharged using this technique. Now one problem using this method that can come up is if you own many drone batteries you may run out of devices to charge before you drone batteries are all empty. In this situation what you can do is plug your drone battery into a traditional power bank. Essentially you are just moving the power from your drone battery to your power bank. This works great considering power banks tend to have high capacities and can take quite a bit of juice.

Using this method is better than other methods such as letting the motors run on the aircraft until the batteries are drained. In my opinion, this puts unnecessary wear on your aircrafts motors.

You can order battery power bank adaptors here if you do not own one already.

Official Mavic 2 Pro/Zoom Case From DJI | Durable, Waterproof and Impact Resistant

Published

on

For the most part, when transporting my GoPro and drone gear I prefer to use a backpack, I do a lot of hiking and exploring and I just find it more convenient. However, there are those times when you need a little more protection and a case that is waterproof. Usually, about this time of year, my girlfriend and I start to plan next summers excursions and trips. We need vacation time booked off of work and this year one of our excursions is going to be a weeklong canoe trip here in Ontario. We will be canoeing, camping and hiking our way along the river and of course, I want to bring my Mavic 2 Pro to capture some nice footage. Due to the nature of the trip, I will need a case that can protect my Mavic 2 Pro from water, mud and all the elements that it could be facing such as rain and even taking a plunge in the river if we happen to tip.

I have researched many waterproof hard cases for the Mavic 2 Pro and decided to go with the Official case that DJI sells for the Mavic 2 series. I thought the layout and size of the case is perfect for what I needed. We have limited room in the canoe for gear so I didn’t want a case that was too bulky but could still hold all the gear I need and this case fit the bill perfectly. The case has a nice finish that looks very professional and is rated for impacts and drops from 1 meter and has a waterproof rating of IP67. This should provide me with an ample amount of protection and keep it safe no matter what situation may arise. This case is a little pricey at 118 US dollars but as long as it keeps my Mavic 2 Pro dry in an emergency it will be well worth it.

Freewell Gear ND Filters For Mavic 2 Pro | When & Why To Use Them

Published

on

Just like every other drone that DJI has released, Freewell gear has made some nice ND filter kits for the DJI Mavic 2 Pro. Now theoretically due to the Mavic 2 Pro having a variable aperture, ND filters may not be needed when you are trying to follow the 180-degree rule and have that slight bit of motion blur on objects with motion. Now let me explain for those who are not quite sure what ND filters do and what the 180-degree rule is.

The 180-degree rule for cinematography states that you should set the cameras shutter speed to double that of the frame rate in which you are filming. For example, if you are filming at 30 FPS you should set your shutter speed to 60 (1/60th second). If you’re filming at 60 FPS then you should set your shutter speed at 120 (1/120th second). Following this rule give a slight amount of motion blur that is pleasing to the eye and brain.

Now there can be a problem when following this rule. On most consumer drones the aperture is fixed and when you set the appropriate shutter speed the image can be overexposed. To correct this you would add an ND filter over the lens which is essentially a pair of sunglasses that cuts back the amount of light that can enter. Now with the Mavic 2 Pro, we have the ability to adjust our aperture, this will also cut back the light that hits the sensor. This again, in theory, eliminates the need for ND filters…or does it? Even with the variable aperture, there are those times that you would still want to use ND filters. Many agree on the Mavic 2 Pro to achieve the best image quality and clarity its best to keep your aperture between f/2.8 and f/5. At this aperture, you would still need to use ND filters on bright sunny days. As well there have been instances when I have set the aperture to f/11 and the image was still overexposed, thus requiring an ND filter.

I have been using Freewell Gear ND filters for many years for my GoPro and various drones I own. I have always been very pleased with the quality and durability and not to mention their very competitive pricing. They offer a variety of filter sets for the DJI Mavic 2 Pro including a standard day 4 pack that includes an ND4, ND8, ND16, and a stand-alone polarizing filter. They also have a bright day 4 pack that also feature built-in polarizers to each ND filter. The pack contains the following an ND8/PL, ND16/PL, ND32/PL, and an ND64/PL. You can also purchase both sets in one package called the “All Day Pack”. For those who like to do long exposure photography with their Mavic 2 Pro, they even sell an ND1000 and ND2000 filter. The Freewell gear ND filters are similar in size and weight to the stock lens cover and does not affect the gimbal performance. You can also attach the gimbal cover when the ND filters are installed, no need to remove them for transport.
