Nice attempt ! Congratulations !

I’d be curious to know the flight time you can obtain with this kind of setting.
My concern is the capacity of the 2 cells instead of the 4 initial cells, that risk to lead to a shorter flight time than expected.
Hopefully, the gain on weight can counter-balance that.

As soon as you can test it in flight, can you share your thoughts ?

Pity I cannot fly my newly swapped battery as yet, cause Anafi is still with Drone Nerds.
Here are some more progress photos and the almost finished product (need to seal the casing back up).

Weight before some hot glue and epoxy, 105.6g.
Onto the next one!
The Pulse 1350mAh 100C LiHV 15.2V 4S battery
each cell has a capacity of 1350mAh. If you take two out of it, the remaining 2S will drop to 7.6V, but the capacity will still be only half of the original 2700mAh. It would only be 2700mAh if you connected it to a 2P system, but then the voltage would be half of what was needed (4.35V) This package would only match the original in the 2S2P configuration.
With this 2s battery, approx. It will fly for 10 minutes. The bigger problem is that BMS is not going to work well because its internal program is still counting at 2700mAh.

Reduced flight time for sure. I will monitor the voltage using the modded app until one can design a case for a thicker battery(I am considering taking up that challenge).
Or when Solaris' shipping rate to the US reduces.
Solaris' batteries are still the better option for anyone with easier access.

Here is a quick concept which may work.

-it must not make the case any longer (to keep the USB charge circuit attached to the battery board)
-increase height for the extra thickness of the additional 2 cells (keeping in mind that USB circuit flex cable)
-add grooves

Epoxy and glue should do the rest.

The battery case will be cut between the power button mechanism and the locking mechanism.
Only the rear part of the case, past the locking mechanism, will be raised
The adapter will be added in the area shaded in orange.

I can vaguely recall someone removing the case to bring the weight down. Not sure if it went down to below 250g though.


Here you go
The problem is that the factory data of the drones matter at the time of registration and not their actual weight. No one will weigh the drones individually.

I have a 3D printer and I can design. The problem is that my batteries are still good and I don’t want to disassemble yet. If I grow old too and have to take it apart, I’m planning a new shell for it.
Or if you undertake to make sketches of the parts that can be built into the battery by measurement (to the nearest tenth of a mm), I can design it and you can print it out. This would require the size of all panels and cells. The height of the LEDs due to the cutouts. I can measure the dimensions of the original battery from the outside, but not the inside.
