I have a few Mini OSD's left over, surplus stock. Never been used.
They can read the voltage of your battery on screen, if you have two batteries they can read both, plus it has a built in timer.
In the photo I used 1 reading on the left that let me know when the unit will switch off as it goes down to 8v and the RHS i used
to let me know the constant VF-2C viewfinder voltage so I could monitor fluctuations that shouldn't happen, Great idea to keep
an eye on things
They are designed for multi copters but you can easily put them into your Night vision DIY build, if you want to see how good they are
then watch my EDNV video.
They are £14 each, plus P&P, you won't find cheaper in UK !

I can even help you with a schematic when you buy one
So PM me if your interested ?
Kind regards Spaltty
