I don't want to fry my new Minimum OSD board but I also don't want to carry two batteries around. It appears that folks are frying their boards by not using two separate power sources. Is this correct? If so, maybe someone could explain to me why this is happening?
The OSD and MP will only tell me the status of one battery...unless I am missing something.
I understand that a separate battery source is beneficial for a clear video reception, however one could also use a filter system.
Any ideas ?
Thanks in advance for your help :)

Vernon nailed it.
Seriously, grab a second power source, double check your wiring and you are good to go.
I have been using the board for ages and it is fantastic, but for the love of god check what you are doing.
Also you can very easily get a second battery voltage/current draw if you want, but this should be relatively unescissary, cameras/ VTx'x draw very little as far as current is concerned.
For example I can run a camera, mimOSD, and a 1.5W 1.3gh VTX for over an hour on a 3s 1100mah battery without a problem. Probobly longer but I have never bothered to test it.
To your second question, you CAN power both sides of the board, but if it is the same line as your main power sources I would STRONGLY advice against it. Broadly speaking this is a terrible idea. You have noise to think of, which has the potential to literally fry the board if you are doubling the input.
Ultimately I would wire the power to both the camera and the transmitter and then run a third connection from that union and connect it to the camera side of the board and then connect nothing to the transmitter side. Of course you should still run the standard video connection.
Doing this you are powering both, but you are also only powering the minim osd once, which will lead to much more predictable results.
hope this helps.
