If by powerpack you are talking about the Lipo jump starter, yes and no...
Wire gauge dictates how much current can flow. for 1/2 amp 12volt the #12 or more likely #14 gauge wire of the battery tender pig tails is OK for that low amperage trickle charge.
But to connect a car battery to it and hit the starter... you would melt the insulation.
To connect the powerpack and hit the starter, same... BUT
But you could probably connect the powerpack and then energize it to transfer energy to the ship's battery and the disconnect before engaging the starter.
I have the battery tender pigtail connected. Under the seat you will find I have a battery tender extension cord AND the batter tender clamps. If I find i have a dead battery, I will connect all that up and hook to a running car TO CHARGE my cycle battery, to attempt a start.
**NOTE if you do this, you will have reverse polarity on the clamp COLORS so connect RED clamp to car's ground and BLACK to car's positive battery terminal... (connect black first to car's positive and tap red to ground to make sure it is little spark)(Big spark and it is backwards) Disconnect something and try to start from cycle battery.
If its got teats or tires, your bound to have trouble with it...
