The 1.3V with no battery could also be a safety thing: if the clamps are shorted, that will drop to 0V and thus it knows not to try closing the main contactor. If instead it sees 9V to 11V, it knows its connected to a dead battery. Same with if the polarity is wrong, as it will see a negative potential and thus not close the contactor.

Fuse need not be accessible if it is to protect against a two-fault scenario that may result in excessive heat. The probability of those exact two faults (say by component failure) is likely very low, but the need to protect against overheating is a safety function if, in a rare case those two specific faults do happen. That is a common design approach and reflects a thoughtful design. If a fuse for that purpose ever opens, there would be other parts that have failed - so making the fuse user-replaceable would be useless.

Great video I have the Genius boost that seemed to be great for the first few years I've owned it. About a year ago the cased separated but it still worked like normal. just recently when i needed it it was dead. I was able to charge it use it and the next morning it was dead again, so now it will charge but will not hold a charge for any length of time. Any ideas?

14:55 you’re not supposed to replace it?! Fuses are the last components to blow when semiconductors are overloaded. Maybe the fuse is there so things don’t catch fire *after* the semiconductors have gone short-circuited.

Excuse my ignorance but at the end why when you press the power button on the genius does it power off both jump packs?

Got a virtually unused gb70, started a motorbike twice, plus a Skoda. That’s it. Tried on a Land Rover which turned out to have a faulty battery, and it won’t work since then. Switch’s on, indicates charged, torch works, but won’t start anything. Any ideas, or repair?? Noco don’t want to know, just offer another at a very slight negligible discount.

What a poorly designed casing for an overcomplicated jump starter . Everything slammed in that case together and almost impossible to repair. The risk of puncturing a Lithium cell and causing a fire is always there. I bet the Copper looking alligator clips are not strapped and not copper either. 2000 Amps claim? doubt it. Great video anyway and fault analyses. Great effort to unsolder and test the SMD components. Did you test the actual jumpstart capacity?

@AintBigAintClever Жыл бұрын

I didn't test them as jumpstarters, just fixed them and gave them back. I've not heard any more so I assume they just do their job now, the person who owns them buys and sells cars so they probably get a reasonable bit of use now they work.

You could have tested whether the PB switch was bad by simply shorting the two N-O contacts to simulate what a good switch would do when pressed. To simply replace the switch without doing this was very shortsighted.

Some might say that to poke around shorting pins in a unit with a high energy ithium battery would be very shortsighted.

@ferrumignis 2 жыл бұрын

If the 30A fuse blows then something has shorted out on the control board, and this fuse blowing prevents a potential fire. It's a very sensible design decision to not make this a user serviceable part, just imagine what would happen when some idiot invariably shoves a piece of thick copper wire in to stop it blowing... Some would say this is a self limiting problem (Darwin award) but it would open the manufacturer to litigation.

It's difficult to get the case closed as it is. If you freeze-frame at 7:18 you'll see that the mouldings aren't symmetrical and would require some modification to get them to fit in, even if the cables themselves can be turned round.

@AintBigAintClever Жыл бұрын

Sounds to me like the battery pack itself could be defective? You know when a car battery has a weak cell, so it may appear to be fully charged but the voltage collapses as soon as you try to do anything "big" with it like start the car? Could be that, with the battery voltage quickly collapsing to below the point where the GB70's processor thinks the pack is fully discharged and shuts down to prevent overdischarge. I could be wrong of course, but that's my suspicion anyway.

@@ELEVOPR I think you'd have to dismantle the unit and put a multimeter across the balance wires, see if any of the cells keel over when jumpstarting. I expect it's a custom cell pack so if the cells are gone it's a bin job.
