Powering Video Assist 7" 12G HDR via D-Tap?

Hi all,
I am wondering if there will be a problem to power the Video Assist from a V-Mount battery using D-Tap to 2.5mm cable? The BM page states that VA is powered by 12V, while my battery states it provides 14.76V via its D-Tap ports.
I've tried it and it seems to work, so I am now worried for the long-term usage of this option.
Any thoughts?
