Hello all!

I am looking to build a long-term Timelapse setup to document seasonal changes in ephemeral pools and wetlands here in northern Minnesota. I have a Nikon D3300 which I am planning on using for this setup. The only problem is I am having trouble finding a trustworthy dummy battery for an EN-EL14 battery. I also have very limited experience with wiring and electronics, so anybody with tips on connecting the dummy battery to a 12v car battery, please help me out!

Thanks!
