The test is a little misleading in one way by starting/ cranking the engine with the original / old maybe dead battery disconnected not a fair test. But that's not the real concern. The real concern is if you do get the engine started with just the "jump pack" with the main/ existing battery disconnected and then one of the leads using the alligator clips becomes un-done /disconnected for a split second, goodbye charging system on your boat or car in most cases. The video kind-ah suggests you could get the engine running then re-connect everything while the motor is running. (Never do this its a very bad idea.)
From the link below:
The moment he disconnects either lead from your battery, it's entirely possible he caused thousands of dollars in damage. Here's why...
Your battery does more than just provide electricity. It also shorts AC, spikes and transients to ground. Removing the battery from the circuit allows those spikes and transients to travel around, endangering every semiconductor circuit in your car. The ECU, the speed sensitive steering, the memory seat adjustments, the cruise control, and even the car's stereo.

With all due respect Top Water, the guy in the video says himself (on a couple different occasions) that he "does not recommend doing this to your own vehicle", he is just trying to demonstrate the power of the jump pack. So of course he has to disconnect the battery to show that ALL the power is coming from the jump pack alone, with no possibility of any battery assistance. How is that misleading or unfair? And I don't see anywhere in the video where it suggests that you should get the vehicle running on just the jump pack, and then reconnect the battery...??? Why would you do that in the first place? That makes no sense at all. Everything in this video was for demonstration purposes only. And lastly, he disconnected one of the battery terminals from the jump pack when the bike was just cranking over, NOT running, again, just for demonstration purposes ONLY. Amazing how we can watch the same video and come away with two completely different perspectives... No criticism, just an observance. Makes me wonder how other's perceive the video.
