Good motors and ESCs should give you information about their voltage limits. With the generic parts, it’s going to be a blind guess. 4S might work and not destroy the components. For a drone of that size/weight, experience says you’ll need at least a 4S system.
Got any of this junk?

Noted, thank you. I do plan to switch from a 3S to a 4S now with all the recommendations. Do you have any resources that provide concrete arguments about the choice of number of cells for a given motor/kv/prop combination? A google search yielded some very ambiguous results for me.

I have the fmuv3 based Pixhawk 2.4.8 considering that it is the easiest to obtain in my region. I will eventually switch to Holybro Pixhawk 4 once I break a few vehicles with this one. I just got some EMAX ESCs and motors to replace my generic ones, so getting better. ;))

Check the datasheet of the selected motor for the maximum voltage range. The general motor type and kv value shows only the mechanical dimensions and speed, but not the specific limits. So these might be different especially for cheap noname products
I was thinking more in terms of performance benefits. For instance is it better to run a relatively high kv motor with a 3S or a relatively low kv motor with a 4S? And of course any links to vehicle weights/class. Basically at this point if my datasheet limits tell me that my motor can work with 2/3/4S (which it does tell me), I have no clue which one to pick for optimal performance.

In my opinion get a 60c+ battery, any rotary wing need amps to change motor speeds quickly
happy flying
Go with the higher voltage if possible.
I know you’re sensitive to my sarcastic sense of humour so I’ll keep it short, I’ve already answered that question.
I rebuilt my vehicle as a quad instead of a hex for lower load to be able to experiment a lot more.
Go with the higher voltage if possible.
Noted, I bought a 4s and a 6s battery to test performance against my 3s. I’m not sure of the exact metrics to check yet but I’m sure I’ll think of something. Thanks for all the help.

Already on it, thank you again! I’m new to tools like ecalc, I’m more used to the good old reading material and drawing board approach but ecalc is proving to be massively helpful.
