multiple head on a single 21700 cell (Sorfirm SP25?)

Hello,
first of all, thank you for the knowledge the community is sharing here. It is my first post but I read the forum since years.

I want to mount a powerful light on a drone (mavic) and did not find any « solved » thread in the forum (need also to switch it on/off remotely, which will be the second question)
It is for light painting photography and my need is to light in all direction down at the same time ( as much it is possible form 20-30 meters).
I tryed lastly to wire some 10w led together with a step up voltage from a 18650 but my lack of knowledge is driver make it a waste of time :person_facepalming:

1/> I read from someone here in a similar topic «… to use just the heads of two flashlights and power them both with a single 21700 cell. This strategy would save you some weight, but would require some diy wiring but would be relatively simple. »
does this wiring is as simple as it seems ?
what do you think about multiple Sofirm SP25 ?
can I go up to 3 heads to orient them as a « tripod »? 4 ? (weight have to be checked)

and here is my second important question
2/> I have a remote which can switch on/off wirelessly (433mhz?), will it works with this Sofirm SP25 ?
(open or cut the circuit will light the heads ? I read that it in not the case with anduril)
do you have other light head in mind for the type of project ?

(already use « lume cube » but need more lumens and less beamed light)

thank you in advance for your advices
