Greetings!
I was wondering if you guys could point out if this idea of mine has a chance of working.
I'm going out hiking and I wanted to shoot a time lapse so I'd need a big battery. Just so happens I have a spare 12v battery lying around. I want to attach this 12v to 7.5v transformer to the battery, then attach the 7.5v to this external battery rig.
My main concern is this - will the 12v car battery have too much amperage capacity to fry it? The transformer has a capacity of 3 amps. Also, the AC power adapter that comes with the DSLR dc kit is only 2 amps. Will the DSLR fry due to too many amps hitting it? Or will the transformer/DSLR only pull what it needs and nothing bad should happen.
Should I include diodes or some other basic circuit parts?
I'm really new to these things so try to explain it like I'm 5 or something, thanks!
