trying to get 12v to power a video Tx. i have a quadcopter with 4 escs (obviously). Can I put two 6v outputs in series or will I blow something up. I'm not sure they would behave like a battery would.

Why don't you take the power directly from your battery? A 3 cell lipoly will give you 12V for the video Tx.

no you can't put them in series because they share a common ground.

Taking power from the balance tap may be bad for the health of the pack. You are artificially unbalancing the pack.

Use a 12V voltage regulator if you are going to use 4 cells.
