### Input voltage limits Turnigy 8-15A UBEC

**Wed Feb 08, 2012 11:35 pm**Hello all,

I hope this is the correct subforum!

In my RC earthmover I use a 12V NiMH as power supply.

I now want to implement a BEC - but it needs to be high-powered.

I was looking at this one:

"TURNIGY 8-15A UBEC for Lipoly"

Do any of you you have any experience whether this UBEC would work with an NiMH pack that has a nominal voltage of 12V? As I found out, those have a voltage freshly charged of 14V, whereas a freshly charged 3-cell Lipo has the 12.6V mentioned on the UBEC. This makes me think that 12.6V is the actual (and not nominal) maximum voltage.

Has anyone given this a try?

I am also mildly worried that this and other "Lipoly-optimised" UBECs will think my 12V NIMH is a defective 3s or 4s Lipo and refuse working.

I tried to google it, but I seem to be the only one (?!) who wants to run NiMH with a UBEC - but I actually need the weight in my machine.

Best wishes

Jens
