The wires on the jump pack don't look very big either.
The largest wire size possible with those blue connectors is 8 gauge. Inside the battery box will be a LiPo battery that probably has 10gauge at worst and 8 at best.
The connector is the weak link when its constant current capabilities are looked at.
There is one of the jump starter batteries claiming it is good for 2500A. The connector will melt. I want to see one in action.
My Juno is 6000 mAh. Use it once or twice a year because I forget to turn the key off. My old motorcycle-water craft jumper cables are 10 gauge. They worked well but I have not used them in over 10-years.
The wires on the jump pack don't look very big either.
The cables on my jump pack are marked 8AWG, the specs in the owners manual say 200-400 amps jump start current. A quick check of some wiring standards says a max of 70 amps with 5' of 8AWG at 12 volts.
I have the exact same model and I added their cable also. I have not used it on my bike, but it has started my 6.7 Cummins diesel several times on the same charge.
OMG...what an entertaining thread:
1) you can not jump start, or even charge, by connecting 2 bikes together via the battery charge pig leads...even if you get the polarity correct.
2) look on Amazon, and buy a well rated battery jump pack.
I made a set of jumper cables that are small and easy to pack.
They have been used several times to rescue others.
Used 12 gauge stranded electrical cable and trolling motor clamps.
I used some heat shrink tubing near the clamps and some more at potential rub points near clamps.
Maybe 5-6 feet long.
Just enough to get to both bikes when parked together.
Positive from starter lug to starter lug.
Negative from muffler clamp to muffler clamp.
Do not clamp an axle.
Stores to size of two cigarette packs since it does not have the thick insulation on wires like normal jumper cables.
The KEY to success is to introduce a float charge into dead battery by attaching cables for a few minutes (from 2 minutes to 10 minutes) depending how dead battery .
measures.
I carry a digital voltage meter/continuity tester.
If i can confirm that dead battery was due to something like leaving lights ON then i may run my bike for a few minutes (2 minutes) at high idle to help charge their battery.
Then turn my bike OFF when they crank theirs.
Caution with lithium jump packs as many will not be able to reach starter lug and ground at same time due to exhaust pipe and removing seat is a pain on some bikes.
The cable wires get warm to the touch but again they function and have been used several times to assist others.
