UpAir One battery mod

Even though all the stuff needed for the mod arrived over a week ago, I still haven’t had time, or the weather did not permit me to fly the mod and actually test it.

UpAir One v3 with battery mod

But today the weather was good, I had some time, and batteries were charged and ready to go.

I am always a bit careful when it comes to new things, and I did not go up that high, nor did I fly too far away.
50 meters up was enough for me to test everything I wanted to test.

The first thing I noticed the moment I took off is that the UpAir has no problem whatsoever lifting the little extra weight.

I was already informed that the first few charges could cause shorter flying times then the 25 minutes that you could get from this mod so I was constantly looking at the voltages to make sure that there was enough power in the bird.

But I can tell you that I was more than pleased with over 15 minutes flying time, knowing that the original battery only gives you around 10 minutes when using the camera.


I landed myself, and did not wait for RTL to kick in. At just over 10.7 volts I landed. Could be that there were a few more minutes left, I did not try it, just to be sure it did not end in a disaster.
I am very cautious, that’s me.

In the end I must say that I am very pleased with the mod, with the flying times increasing after a few charges, things can only get better.

To sum up the mod, here are the parts you will need:

First, 2 pieces 4000Mah 3s Lipo’s
I got them from Hobbyking.

Multistar 3s 11.1v 4000Mah LiPo
Link for the Lipo’s

Secondly you will need a XT60 splitter cable, this makes it possible to connect 2 batteries to 1 connection, I got it from Hobbyking as well.
The photo is a modded one, more on that in this post

Next thing you need are 2 female spade connectors, these will replace the XT60 plug that is on the original cable.



You will also need the “UpAir BigAss Lipo Door” from Michael Roy.
You can get the 3D file from his site

Link for the 3d file

And you can have the file printed locally through 3D hubs.

When you have it printed it could look like this, depending on the colour of your choice of course


Once you have everything prepared it’s also nice to know what it + and what is –
We’ve got you covered as well.


Now it’s only a case of connecting the lipo’s to the splitter (make sure you have covered the connectors on the other side!)
Slide in the lipo’s, connect the connectors to the drone, put on the lipo door and off you go.

I like the mod, especially knowing it will improve over time.


  1. Good morning my friend, I wonder if you could help me? I made this change putting a new battery, and it happened that the drone deregulated all, stopped running a motor, I managed to calibrate, but unbalanced the rest, my drone only accepts the command to rise and not lower, just below with the return home, I do not know how to calibrate again and leave in factory mode, therefore I can not use it, if you know how to solve please help me.

    Thank you

    1. I have had 2 crashes in 10 minutes with this mod just 2 weeks ago.
      First it looked as it was a lot of interference since we were flying with over 30 drones.

      But last week I wanted to fly again with this mod, and the drone did an auto land, and had troubles staying in the air.

      After that I haven’t used this mod again, only used stock batteries, didn’t have any issues at all.
      I think this mod is not as good as it looks.. it gives greater flying times, but makes the drone unreliable…

  2. Does anyone know of a travel charger(using 12v) or have modified a LiPo charger to suit travel.


  3. How do you connect the XT60 Y-cable to the connectors of the drone?
    And what is inside the original cap? Only level indicator and charge device?
    Do you compared the discharging graph of your replace batteries with the one of the original battery?
    Do you charged each of the 4000mAh replace batteries alone with a charger outside the drone?

  4. I have use this Mod an the Drone fly 25 minutes. But i have not use the flat Plugs for Car electrics. I have solder the 2 Wires from each xt connector to the main Wires form the original Lipo Plug .
