granted, a jump pack can start an engine without a battery
as brought out dead short currents.
but what i was bringing out is
IT IS THE VOLTAGE BOOST THAT DOES THE JOB
the whole thing is that the ion battery will maintain high voltage to near its depletion.
it takes diff'l to make current flow, aka, voltage.
as voltage drops internal resistance limits current.
by maintaining higher voltage less current in needed as brought out in the link.
i will concede that i jump the gun on the dud battery.
You are so full of it!
Your post that started all of this literally says, and I quote:

voltage is the electrical force that causes current to flow. the water hose analogy while not truly correct it does present the concept. it is the pressure that starts flow. think of a spark plug, it will only spark if the voltage is high enough.
the starter needs a certain voltage level to over come the resistance by supplying the magnetic field that pushes against the armature. once moving, the amperage carries it through.
like a manual foot. your leg pushes against the mass but once the mass is moving, its weight carries it through. need proof, ever yanked on a manual foot only to be suspended in mid air???
Had a jeep sitting flat dead in my drive for 3 years, battery wouldn't glow a test light. My Antigravity XP10 jump pack which only showed 3 bars charge fired that hulk up, guy drove it off. Your thinking about the electronics on these newer bikes maybe, they have a definite voltage threshold it dips below they won't fire.
I installed the NOCO GBC007 boost adapter to use with my NOCO boost pack. It doesn't work with all of their boost packs so be sure to check the compatibility.
As others have said, the charging harness is only for charging and can't carry sufficient current for starting. On the other hand, the boost adapter has heavier cables and is designed for the jump starting.
I gotta get some of these.
I've carried a jump pack in the car and van for awhile and just started carrying one in my saddle bag.
I hate having to remove the seat for anything.
My battery has been getting weaker by the day and I've had to run the generator a few times just to charge it for a ride.
Just bent over the Harley shop and got an OEM battery for $230. And hopefully that will be that for awhile.
Plus I just picked up a cheap solar trickle charger because as I stated about the generator...
We live off grid 😁
That plugs into the power jack and I can stick it on the windshield.👍
once again it is the voltage boost. case in point: went to the farm and cut the pasture, came in and went to start the hd and a no go.
all i could find was some old 18ga lamp cord long enough to drop down the tractor battery to the hd. let it sit about ten minutes and removed the wire and it cranked up and i got to go home.
it was the voltage that got the starter to turn and what was left of the hd battery capacity in amps that carried it through.
some jump packs have safeties that prevent you jumping a extremely low battery and some better ones do have a by pass but when used, no safeties in place.
a low battery is a power sink so that jump pack better get it right the first time or you will have few tries left. ion batteries come in many flavors but most will recover very quickly unlike the lead batteries that require time.
some pack mfg's recommend that you let the pack equalize a tad before starting, once again to bring voltage up.
a common cell in use for power packs have around 40 amp dead short at around the 4 ish charge voltage, they just stack them up to get, WHAT????? the required amps, NAW, the required voltage.
take a brand new battery and let it parasitically drain as voltage drops, so does amperage output. when you get 10 ish volts, the battery will fail to turn the starter over on the majority of the cars.
clip and paste from a jump pack maker:
A good quality portable jump starter can typically start a completely dead battery, thanks to modern technology advances. Today's jump starters use powerful lithium-ion batteries that can deliver the significant cranking amps needed to start a vehicle with a fully discharged battery.
However, success isn't guaranteed in every situation. The age and condition of your car's battery play a crucial role – if it's very old, severely sulfated, or has internal damage, even a powerful jump starter might not be able to get your vehicle running. The effectiveness also depends on the jump starter's own capacity and your vehicle's specifications. Larger vehicles with bigger engines naturally require more power to start, so you'll need a jump starter with adequate capacity for your specific vehicle.
Before using any jump starter, it's essential to consult the manufacturer's instructions for both your vehicle and the jump starter itself. If multiple jump-start attempts fail to start your vehicle, it's likely that your car battery has reached the end of its life and needs replacement.
case in point: went to the farm and cut the pasture, came in and went to start the hd and a no go.
Rounders said you should not have put it on a battery maintainer as this happens when your battery is bad, will start once off the battery maintainer, but when you get to your location and the battery sits a while - no go

Does anyone make a cable that will handle the booster pack and have connection for a tender?
Or..what size wire would I need for a booster pack and will the tender work with the bigger wire size? (if I make my own)
What I have now is 2 sets of wires hanging out. 1 for the tender and 1 for the booster pack.
