SmallHD 502 to D-tap

I want to D-tap my 502 SDI monitor to the D-Tap on top of the interface o the back of the Movi Pro,
do any of you know where to get a dummy battery with a cable?

I have a dummy allready, but that one is for usage with 220V adapter

 

I found one, just a minute ago, will this work?

I read something about voltage issues, specifficaly on the 502.
Not issues as in faults, but things to be aware of
