Looking for some input on the following:

I am wanting to run a stereo and amps off the primary 98v lithium pack using the DC/DC converter in the link below. So as not to have to install a separate 12v car battery and charge it separately.

Yes, I know the onboard DC/DC can do 20 - 30 amps but I have other things planned for those amps (lights, camera, etc)

I am concerned with the possibility of ground loop noise or other interference not being the primary ground of the cart.

Has anyone done this? Should I be concerned about feedback/whine?  
Any input is welcome.

Wow, that is a neat converter. I don’t understand the low price for a meanwell.  
Common practice is grounding 12v systems to frame. Don’t see a problem trying it both ways. Isolated or grounded.  
Now if you could find a dc-ac with a wide range input.

Agreed, MeanWell makes good stuff from my past expericances in saltwater tanks and LED drivers.  
What would you use the DC to AC for?
