Does shinobi use NPF style batteries? I spent a lot on vmount solutions, don't hardly use it since I've found these babies:.

22 dollars and you need a Alvin's DC to Two Pin cable (or off brand)

Plug the battery into your monitor use the DC to two pin and boom 2.5 hours of recording is what I typically see, at the price I grabbed a few and don't have any problems using them with the lp-06 in the camera (registers as DC until you do a battery swap then picks up the battery while you do a swap)

I've found it to be the cheapest and easiest set up. For reference I use bmpcc, tilta cage and zhiyun monitor (saving up for a better monitor).
