Hello, I recently bought a 12v deep cycle battery 75 AH and I made a battery box following these tutorials:
and
(no need to watch it ofc, just to understand the basic idea). Here is the outcome:

I know the pictures quality is not really good, but hopefully it will be good enough.
The problem I encounter is that if for example I power the second switch which turns on led lights, the voltage that is then going to the rest of the switches is getting lower, for example:
I turn on the first switch(turns on voltmeter and gives power to the rest of the switches), the voltmeter reads 12.5v, then I turn on the second switch, and the voltage is dropping to 12.4v, the third switch is used to power my telescope, which takes pretty high current, so whenever I use it the voltage drops even further to around 12.2v or even 12.0v.
Now I obviously understand that voltage drops will happen, but not that much. I have another voltmeter connected directly to the battery, and the voltage will drop from like 12.5v to 12.48v or even slightly lower, but not more than that(thats the way it should be ofc).
I have tested the wires, and it doesn't seem like there's any loose connector or something similar, when using my multimeter the voltage transferred to the rest of the components are as should when everything is turned off, only when I power something the voltage that is transferred to the rest of the system is getting very low.
I'm currently using 16 gauge cables for all the components, and 14 gauge cables from the battery to the system.
Any ideas? I'm not really sure what I can do about it. Thanks!
