Does it have low-voltage protection? Like low voltage cut off.

  • I don't believe it does, you may have to make one

Is there a spec sheet available? What's the minimum input/output differential in 6V out mode?

  • when I used them in 5volt, and they tended to be on the high side of 5 volts under load(around 5.2) they work great as a BEC for RC. ^ volt seems closer. they didn't come with a sheet, I used them as-is, never looked around for any docs. 7.2 and 11 volts seem to work fine.

I am only getting 2.5v out of two of these. Everything is hooked up correctly, and Im getting 9v from my nimh. Did i break them by using nimh?

  • Are you sure you are testing from +5 to ground and not to + 9? Seems unlikely that two would be bad. Your battery chemistry should not matter.

Do the leads have connectors?

  • The 5v side has a standard servo connector, the input side has nothing, just bare wire so you can solder to your power distribution board.

Will this work for my lights on my scx10 running off of a 850 mah 2s lipo

  • Depends on the amps and voltage required for the lights. I would also not purchase this one, I have purchased two and both were solder incorrectly. Look into the Turnigy, they are well built with less RF.

Can you split the output of this ubec to 2 different things as in a stepper motor and a camera as its main power source and run simultaneously?

  • as long as you do not exceed the rated output of the ubec you should be ok to split the voltage however you wish.. once you overload it , it will fail..

Both the mini dvr and the osd system i bought are 5 volt but this unit i bought its output is 5.25v will this ruin my osd & dvr with too much voltage?

  • No, I have used this same one for years with my osd, lights, flight controller, etc. Works great!
