I think itā€™s a great idea

I think itā€™s a terrible idea because you can fry your vesc if youā€™re braking when the fuses blow.

Thatā€™s very unlikely to happen since braking currents are much lower than discharge currents. If the fuse blows, it will probably be while accelerating and not while braking.

I would still rather fry my vescs than burn down my board (again) in case thereā€™s a short.

So insane, you are always builing different boards, all the way through eskate universe. Most busiest guy ever! Thats awesome,dood!

He probably got the itch though, short jump from there to DIY once you realize 25 is cruising speed.

@janpom while adding a 60A fuse here could add a tiny amount of safety risk, adding six 10A fuses in parallel is significantly worse imho.

Be really careful with that, if that was in my home Iā€™d immediately cut it up and discard it as a safety hazard.

Any tiny differences in resistivity could lead to a flow imbalance, and if any one of those six blow, the rest will quickly blow in succession

experiments #forscience are great though; carry on

Has anyone considered adding a diode to allow regen even after blowing the fuse?

Yes, I realize that. This actually didnā€™t work out quite as I have imagined. I thought I would be able to keep the loop key way smaller than if using a single automotive fuse. Itā€™s not that small at the end though.

Anyway, I will test it very carefully before deciding whether I want to keep it or not.

One other problem I realized is that the terminals of some fuses are very close to each other and may actually touch and bridge the fused connection. It would have been better to put a heatshrink around each fuse.

The fact that the 2mm hex wrench broke before the bolt stripped-out can attest to the quality here.

Wera Hex Plus for lyfe

Any other wrench would still be whole ā€“ but instead of buying a new wrench, now you have a stripped-out grubscrew fucking up your skate. So instead of a $5 problem, itā€™d be a $1500 problem :rofl:

Lol thatā€™s one way to look at it. It didnā€™t seem like I was cranking on it hard enough to snap like it did but it do :man_shrugging: I suppose I am thankful it didnā€™t strip my motor shaft grub screw beyond removal

Thanks for the link :+1:

Iā€™ve had the same thing happen with Wera Hex Plus 2mm wrenches and Iā€™ve had overtorque situations with other cheap 2mm hex wrenches

The Wera snapping is by far better

The other ones destroy the bolt AND the wrench simultaneously, then youā€™re super-fucked

Put some penetrating oil on it while a new wrench ships, you will be FIIIIIINE

@janpom similarly was done in the old forum with just one automotive fuse. Donā€™t remember who did it, but he removed all the plastic parts of the fuse and just used the fuse blade. I think you can get the midi fuse blades just as they are without casing.
If itā€™s still too big you could just print a T shaped cover for the loopkey and hide the fuse inside there.
