Does hot glue work to enforce/protect my soldering joints/points? Answered

I made a custom drone and I want to protect the soldering joints on the power distribution board. 
And it still needs to work after hotglue-ing all of it haha.

I certainly have used hot glue to insulate and protect joints before and here is a mini instructable suggesting the same. You can always peal it off if required.

If your solder joints are pointed they have porous oxidation difficulty and may break if stress flexed like Tinkrmind said.. Also don't use the lead free solder because the military, hospitals and NASA avoid that troubled solder like the plague it is.. They know it will fail...

About Solder,
Hospitals, the military and I all Hate lead free solder it cracks, it ages,
it is hard to tin a tip, it is Bad News.. When a joint fails lives are lost, so NASA the military and hospital electronics all have a government wavier to use real tin-lead solder.
Avoid it unless you have to sell to the abused American consumers.
I have been using tin-lead solder over 48 say 50 years and politicians making stupid technical decisions have not made me ill or lead poisoned me in any way..

I am sure you know the story "Alice in Wonderland",?

Well the character "the Mad hatter" comes from a real life situation. A Hatter was a profession, that of making hats, like the big top hats of long ago. The hatters used mercury to clean and form the felt, and things like beaver pelts, so they exposed themselves to a lot of mercury. Because of this many of them had mercury poisoning which made them crazy, and thus the common term of that time "Mad as a hatter".

I have never heard of any kind of term for soldering. "Crazy as an electronics assembler". So in comparison to the good old days I think the danger is pretty small.

There were more then Mad_Hatter_Makers as I heard the story.. The brow sweat would prematurely discolor the early brim materials until some early alchemist found rubbing Hg into the brim made it keep its newness for a longer time.

Well, it depends on the situation, a photo of the joint would be helpful. But, with solder joints, you should mainly be worried about high frequency vibrations that can stress the joint repeatedly.

My concern is mainly because of the battery input which exposes it to high stress from plugging and under plugging

I personally wouldn't use it, but I suppose it can be used. A soldered joint should be strong enough on its own to protect the electrical integrity. If it's not it should be redone!
