DSLR Battery Grip 2x 18650 - Nikon D810 / D800

thingiverse

We always have 18650's on the charger for our many devices, so this battery pack has been such a great idea! The bamboo pin alignments & 1/4" tripod hole in this design are to suit a D810 / D800, but you could easily modify their position in Tinkercad to suit the base of your camera. Just check that your camera can accept 7.4v. The best way to do this is to look for your cameras dummy battery online and check that 7.4v falls within the input voltage range in the specs. For example, the dummy battery for my D810 states Input 7.0v - 9.0v. Many other dummy batterys for Canons will state Input Voltage: 7.4v to 8.4v - which is also perfect to use. I used 3 lengths of 0.9mm silicone bronze MIG welding wire, but any other springy, stiff, conductive wire will work. For my NIKON D810 I purchsed an "EN-EL15 dummy battery" from eBay for $15 AUD.
