My controller currently runs on batteries, but I want to replace it with a power supply. I have a power supply that allows you to adjust the voltage. How many volts does a typical mount need?

Important question! Why is there a film recording of an (Apollo 11) lunar capsule that launched from the moon to Earth, with the lunar capsule even being tracked with a film camera on the moon. Who recorded this film or video? Was a cameraman on the moon at that time and was he left behind?…

E.g. Both are 15 and the astronaut flies through space for 5 years The 15 year old person on earth would then have to be about 65-70 years old, right? Would the conversation then be in slow motion for the 15-year-old astronaut?
what and how many batteries are there?
Standard are AAA or the thinner (AA) batteries that are connected in series.
Each battery has 1.5V in series connection then number 1.5V .
If the battery should be, then reckon with 1.2V per “battery”
These are 8 normal batteries, so AA
I expect 12V (8 x 1.5).
But you should check if they are all connected in series. It’s hard to be.
