12 volt capacity for Gem 2016-2019

Adding 12 volt accessories to a GEM uses amperage that is supplied by the dc/dc converter. I am wondering what is the max. amperage that can be expected for that converter?

When adding a massive radio system is it best to have a separate high voltage to 12 v. dc/dc converter connected to the main battery pack?

My current system will all lights and radio can get close to 40 amps.
I have stayed way below this because I don’t know what my limit is.
Adding radio amplifiers will make this worse.

I do not see this answer in the Service Manual. If you do please tell me the page.

I don’t know that I would push the Delta Q to 30amps continuous but they state you can.
I personally would install a second DC/DC converter for the stereo.

300 watts or 300/14 amps.
Buffered by the parallel connected aux battery.
No reason you could not use a larger battery or converter.
Or add one for accessories.

Thank you all for this data. It is easy to add an additional dc/dc converter to protect the onboard system.

Could you tell me which wires to connect the second converter to so that the ignition shuts off all power?

If your Gem has a stand alone Dc converter, You can add a second converter by switching to a Deltaq with a built in dc converter.
