Mavic Pro Battery Mod

Cruzroy your designs, I need to make some mods on the new 1 but, nice design will be using both for sure.

CyberNate how much is the cost of antenna mod with amplifiers, and would it help 2 miles out but down 40, 50 feet to get wildlife Video.

Hi.
That design is really nice, could you please post the stl file (if you want to share it)
I was thinking using two of these battery`s:
3.5Ah 11.1v 60W Endurance

i like the red color, are you going to do a flight video to show how long it can hover or fly, i know hovering take more power.....nice job

OK guys....FOR FIXED WING MODE on the mavic pro..........

Im going to try, I never think about it till I've gone thru all the batteries, bare with me

My new 3s 5200mAh LiHv 318g and holder battery 3d paint 25g, tested on flight time - Take off at 98% and flight time 30mins, landing at 16%.
and 3000mAh Lipo is 27mins.
What think this is good with 5200 Lihv weight? and flight time good?

What's the stock flight time with the same flight pattern?

Weight of 3000? Also HV?

What's the handling like 5200, 3000, stock?

I tested few move hover, 2mph - 3mph wind with both 5200 and 3000.

Zop power 3000Mah 30c is 148g

from drawing board to reality just had to print it, like it or leave it

This is not an ideal test. The craft needs to be moving at 15 mph or higher. There is too much prop wash when you hover, which is especially bad when under heavy load which makes it even less stable. There will be more lift at speed due moving into clean air. I would expect you to get similar or more flight time while moving at 25-30mph.

The problem with these wings is that the Mavic pitches forward while moving forward. Those winglets will actually create downforce when the Mavic is moving forward. They need an aggressive positive angle for forward flight. Of course then you couldn't fly backwards as that would also make downforce.

Anyway, I guess they are small enough to not affect lift so much.

Sorry, I never saw this post. Yes, those boosters with good antenna would help significantly; however what do you mean by 40, 50 feet down? You mean at an altitude of 40 or 50 feet. That really depends on the terrain. Anytime you have objects between you and craft, signal is cut way down, even when boosted. If there is mostly clear line of sight, no problem.

Cost is around $80 per amp and antenna mode is around $150 depending on which one you choose and whether you install yourself or have it installed. If you are using dipole or panel antenna like nanosync, one amp should be good for Transmit side. You can amp the receiver side as well, but it's a small gain.

Thanks,
Moving at 15 mph or higher... means wind 15mph from outside or see dji 4 from speed mph (15mph)? i am slow learning.. do you have on video? show Screen Rec with dji app will help know about dji 4 say wind mph or speed mph. Which use Sport mode or GPS mode for on long range?

tips, kinda vague but i think you get the idea

Nice that's good for make it. Thanks.

Where there copper 24 awg link? I need 2 x JST with wires for battery clip "Y". Battery 1500mah or 1800mah lipo with JST... fight time 34-35mins for my Mavic..

One thing I've noticed with the battery mod which attaches to the Mavic battery pins is that the contact with the pins is not sufficient. This is apparent if you see that the external batteries are not depleted after your flight. I noticed that as the battery mod was repeatedly removed and mounted, the connection gets worse and the external batteries are not as effective. It becomes necessary to put a drop of solder at the contact point of battery pins and the copper plate of the battery mod. You should always check the external battery voltage after flight to verify that the amount of power used is in line with the Mavic main battery. If not, you have poor contact with battery pins. I think many are seeing this issue, as I remember one guy saying he could get 2 flights out of the external batteries before needing to charge them. This should never happen. The voltage of external batteries should always match the Mavic battery after flight. If Mavic cells are 3.7V/cell, that's what you external cells should read, or be very close.
