Not once you start plugging heaters and stuff that takes more than miliamps like that contactor.

Energica doesn't use a DC 2 DC converter.

Actually Energica bikes do have a DC/DC converter, located inside the battery pack. This unit provides all the 12v power to the bike when the key is turned to the on position.

Regarding the OP's question about the power capabilities of the 12v coming off fuse #6. The earlier bikes shipped with a 5A fuse in this slot, the newer bikes (2019?) come with a 10A fuse.
I am not sure if there was also a change to the wire gauge of the harness.

OIC.

If the DC2DC converter fails, is it replaceable or does the entire battery need to be replaced? And how much current can it handle and how much does the bike use? I am really asking how much current can be safety drawn from it in stuff that is added to the bike.

IIRC, Energica doesn't use a DC 2 DC converter. It uses a battery tap for it's 13 volts.
 

Can this be confirmed please?

Nope! It was just unconfirmed. See the message above from  Demoni.

I am not sure what made me think it used a battery tap, I wonder if I saw a block diagram somewhere that simply showed the wire coming out to the battery pack that was really from the DC2DC converter that's located inside the battery.

Phew!  Thank you for the clarity - I should have looked.

BTW - if a 2nd DC-DC converter is added to bike, same Energica one integrated to battery pack but obviously packaged for auxiliary use, this could be an approach to sourcing more juice for winter heated clothing...just a thought.  I'm planning a small LiFePO4 14V pack tucked into tank bag versus any invasive mods to bike...plus, exposure to sub freezing temperatures for charging (regen inclusive) causes irreversible damage to cell anode structure hence why I'm keeping an ICE vehicle available for extreme cold riding.  Begs the question, does Energica employ a low-temperature inhibit for charging?  Harley-Davidson does not based on the first three episodes of Long Way Up.

IMO, ICE bikes are much better for cold weather. Engine heat helps on some bikes and adding to the 13 volt system is usually not an issue. And your range isn't reduced as it is on electric bikes. Just better all they way around, IMO.  I have ridden in the 20's (F) a few times (-4c). I would not then consider an electric for here where it can get very cold in the winter.

In the SF Bay area, and many other places, having an electric for all year would be fine, IMO.

But in hot weather, electric bikes are great. Best range, no engine heat. No need to add heated stuff.

I got caught in the snow-thunderstorm last winter.

It wasn't the parts of me facing the bike that needed heat!

I got caught in the snow-thunderstorm last winter.
There in Santa Cruz?

The day I purchased my Moto Guzzi, it did not look like snow when I left the shop with it. By the time I got it home, it was HEAVY snow. I could not even get the bike into the garage because by then the snow was too deep in my driveway. And there were car accidents caused from the snow on the way home!  Getting the bike  to my driveway was one of my most scary rides and I am amazed I didn't fall off the bike by the time I got it back. I think those dual sport tires on this bike did great in the snow!

It wasn't the parts of me facing the bike that needed heat!
My TTSE has heated grips, heated seat, traction control, ABS and about the best wind protection of  any bike I own. An excellent cold weather bike. And it is wired up for plug in heated vests and gloves.

The Moto Guzzi does well also in the cold also, it has those big leg warmers called engine cylinders. But my Harley has the hottest grips. Six selections from mild to burning hands. My Moto Guzzi also has the heated grips. Over all, my TTSE is my favorite cold weather bike.

I don't even bother with the electrics in cold weather.  So with those, I don't care about adding heated anything.

At Skyline, yeah!

I hadta get to San Jose and there were thunderstorms and I have rain gear so I bundled up and shot the gap between lines of storms but behind the thunderstorms it decided to snow so by the time I got to the top, it was slush and snow everywhere.

I decided (wisely I think) not to stop and take pictures.
