I may be just commenting on something you already know :
The DJI battery pack is a 4S High Voltage rated pack ... not a normal rated LiPo ...
The DJI cells are what are termed LiHV ... and they are rated to full charged at 4.35V per cell.
Normal LiPo cells are rated to 4.20V per cell.
If you were to plug in normal LiPo 4S packs to your full charged DJI LiHV pack - I would advise you against such. The first thing that will happen is the LiHV pack will try to equalise with the lower voltage LiPo cells ... and the consequences cannot be overstated that you run serious risks.
If you are going to plug in extra packs - PLEASE make sure they are LiHV packs ... AND that each pack is at similar state of charge.
It is extremely unwise to connect a part charged pack to a full one ... the initial current flow can be sufficient to create what is commonly termed "magic smoke" ...
Be sure you contain the smoke at all costs. I notice an apparent lack of any fuse between the packs. My experience of 30 years repairing electronics is that upon letting the smoke escape, devices fail to function as expected. My prediction is any added flight time will be mitigated by extra weight. But test flights will be interesting.
I look forward to hearing flight results, complete with photos of the incident.
There are various Youtube videos of using such add-on packs ... the simplest and best is the copper plate adaptor that needs no cable soldered to the battery board.
Yes - the increased flight time is not a linear factor ... it is a compound result of increased weight vs increased capacity.
I have various twin battery machines and usually I get about 60% flight time increase for 2x capacity. But that's only an indication as it depends on model etc.
Hope you get good results Jordon i fly a P3 A with a pair of 5200 hv lipos made over 40 minutes and a long range flight of 11.4 miles out and back thats a total of 22.8 with 3 % left
