Is it a bargain to get a Phantom 4 Pro battery for my Phantom 4?

Many friends expressed their interests since DJI launched Phantom 4 Pro. However, some were paying special attention to the battery of Phantom 4 Pro.

The capacity of Phantom 4 battery is 5350mA, the flight time of Phantom 4 is 28min; while the capacity of Phantom 4 Pro battery is 5870mAh, flight time of P4P is around 30min. So we used P4 battery on P4P and P4P battery on P4.

Theoretically, when Phantom 4 uses the battery of Phantom 4 Pro (with 520mAh more), it should be able to fly longer. Since P4 and P4P have different weights, the battery level does not follow linear change. Here is test result:

Test environment: outdoor, breeze

Test method: P Mode, with forward and downward vision, hover without recording or taking photos until it is forced to land with low battery.

As you can see:

P4 battery（theoretically 5350mAh） P4P battery（theoretically 5870mAh）

P4 26’’ 02’                          29’’24’

P4P 25’’42’                         27’’56’

If you are paying enough attention to picture above, you will find battery level and the number of charge/discharge cycle. As a battery goes through more cycles, its capacity will drop. The capacity could be little higher than official number. So for all Phantom 4 Pro batteries tested, we tried to keep the capacity difference smaller than 100mAh.

With similar wear rates, we found a Phantom 4 can fly around 30mins with a P4P battery, extending the flight time by 3 minutes; while a Phantom 4 Pro flies about 26mins with Phantom 4 battery inside.

Phantom 4 Pro battery costs $10 more, but extends Phantom 4’s flight time by more than 2 minutes. If you have got a Phantom 4 and want to stick with it, it’s quite a bargain to buy some P4P batteries.

If you plan to buy Phantom 4 (aircraft and one P4 battery) with $1099, you may want to add 2 more P4P batteries. Total cost is: $1099+$169*2=$1437 , making it much cheaper than P4P.

Hover Camera CES

The Hover Camera Passport, on display at CES 2017 is a special drone.

Hover Camera is a drone that comes with “advanced” AI technology that can actually track the person’s face. This means that all you have to do is get the drone to recognize and lock onto your face, and you’re good to go as the drone should have no problems tracking your movements. Once you’re done, you can just grab the drone or tap the app and it will land.It is a drone that users can toss in the air and then follow them around.

The Hover Camera Passport is not your typical quadcopter design.It looks like a book when folded and it truly can fit into a purse or backpack with ease and the cage protecting the propellers keeps them from harm. It’s also very lightweight at just over half a pound. You can pack it up and bring it with them wherever they go, as opposed to more typical drones where you might require a special carry case.

The Hover Camera Passport costs at $599.Looking at the current drone and digital cameras market it becomes very clear that Hover Camera is an overpriced product. However if you can accept the value that Hover provides for the price it definitely will be a great choice.You can pre-order it where it is expected to ship in the next 1-3 months
