I made a battery plate that runs on Dewalt 20V max batteries

II guess it's popular to replace the kids "powerwheels" electric motorized cars with Dewalt batteries. That's where I got the yellow part. Wired up a DC-DC step down converter based on LM2596 (92% efficient) wired it up in a small project box. Next I'll put it in a thinner metal enclosure and add a V-Lock (you know...the male V part) It's putting out 8.3v for my canon 5D3, but you could set it to 14.4 or whatever you need. When all you anton bauers are dead, just borrow a drill from the carpenters and you're good to go!
