Is there a full 10 amps avail, if so where?

Minimum wire size for:
[1]  5 amp - 18 ga
[2] 10 amp - 16 ga

Fuse 6 - rated at 5 amps  [per the manual, pg 70]

Back of F6
   bottom wire is brown, looks to be a 14 ga wire (at least 16 ga)
   top is blue, looks to be 18 ga

F6 is the source for the unused connector (hidden behind the dash), normally used for the official USB outlet.

Gauge of wire safe for amps varies by length as well.

Length is more about the voltage drop than safety.

See attached for a chart.

Crissa - Thanks for the reminder.

I've decided to keep F6 as a 5 amp fuse per the manual.

As of this writing, having limited info, I'm unwilling to make any mods to the bike that might damage it, e.g. [1] replace the 5 amp with a 10 amp fuse, [2] tap into the brown wire.

What is it that you're trying to run at 10 amps at ~13 volts?

Any combination not to exceed 8 amps.

Items -
Tracker (APRS)
Driving / fog led lights
GPS
Cell phone
Dash cam
Heated gloves
Heated jacket
Heated grips
maybe other items

With only 5 amps available, I’ll have to decide what’s a priority.

Off the bike, I’ll have to perform a load test of each item to ensure the 5 amp max will not be exceeded [actually 4 amps, no more than 80%].

When I run the 17 Eva, I normally ride all day, between 250-450 miles, so come winter, heated items would be preferred.

With Electrify America now charging per KW vice per minute in California, I'll probably try a 600 mile day soon.

Heated gloves

I use these with a couple of spare batteries. They are quite warm even when turned  off.

Your "priority" on the other stuff should be the stuff that draws low current. Heat and lamps draw high current, the other stuff should be low enough to add.

I added a 12 volt outlet to my Esse Esse 9, but I usually only have my GPS plugged in, which I have a charge station directory for each  AC & CCS charging.

I went with the battery powered Gerbing gloves to avoid having to find a tap for my 12v Gerbing gloves. I ended up throwing in my 12v gloves when I sold my Trophy to make room for the second Energica. Since it rarely gets below freezing on my commute here in the SF Bay Area, the battery powered gloves, heated grips, and a good sweater/sweatshirt layered under my winter jacket is sufficient for me.

I figure a 12 volt outlet can be used for other stuff as well, such as for a small tire pump if necessary. IIRC, I am using a ten amp circuit that isn't used for other stuff, such as the bike's heated grips that I do not have and I carry a small tire pump that draws a bit less than that under load.

IMO, it would make a lot more sense if Energica would have a 12V outlet instead of USB. It is easy to convert 12 VDC to USB as necessary with a one dollar plug in converter thingy sold at the dollar stores (half amp). Or get a better two amp one elsewhere, still cheap.  Not so easy to convert the 5 VDC USB back to 12 and then the current would be too low for most things anyway.

Even on a bike with the heated grips, that  circuit would be a good ten amp circuit to use, just keep the heated grips off while  it is used for other stuff to not get over the ten amps.

On cold days, I won't be using electric anyway. Reno can get very cold. I have ridden in the 20's a few times and the TTSE is a great for extra cold weather. I have the heated seat as well as the heated grips on that bike and it is wired up for my heated jacket and 12 volt heated gloves as well. And then it has the traction control which could help if I accelerate over ice that I cannot see to avoid.

Does anyone know how many watts the DC/DC converter puts out?

IIRC, Energica doesn't use a DC 2 DC converter. It uses a battery tap for it's 13 volts. I don't know how much current it could handle, but I would not want to add much more than ten amps to what is already there. The wiring for the 13 volts doesn't look like it's designed to handle much more. I think your best bet would be to add your own fuse and see if you can get to the circuit they use to feed their fuses. That would have to be designed for the entire 13 VDC load and would be the best place to get your DC from.

All I did on mine was to run wires from the SS9 USB input wires which is  my 13 volts to run my GPS. IIRC, I should be good for ten amps, but so far have only used my GPS with it.

Where is it getting the 12v if it has no DC to DC?

If you tap off a battery half way, how do you balance the cells back?

Batteries are made up from low voltages cells in series.  Simply tap off at the voltage you want.

In fact, I think even Zero uses such a tap but also has the DC2DC converter. Didn't we hear here that the tap was used energize  the contactor in the Zero? I think that was what Brian  said here, IIRC.

If you tap off a battery half way, how do you balance the cells back?

I don't see an issue there as when you're charging, you're not using and balancing I would think would work normally.

But the more you use the diversion, the more those cells age disproportionately to the cells later in the pack.  So it shouldn't be used for anything but the tiniest of loads.

All that 12 volt stuff is a tiny load compared to the battery cell capacity.
