I need to round the inner edge. I could have had it modelled, but Iām impatient and like doing things myself
I will make a urethane riser between the deck and the bracket which will act as a dampener and a cable route.

Bro just buy another 44 demonseed you know you want to.
Already got 2. And theyāre not easy to come by. You can rest assured that if I find another one Iāll probably buy it
Not if I find it first. I need another build this year like a second pen15 hole.
Current builds
1 Tubby 40% completed
2. Luminar 10% no deck yet
3. Puppy started today 30% Pink and girly itās for my 6 year old (well thatās my story).
You have likely more on the go.
I think you added an extra 0 after 100 by mistake
@janpom
Cool idea! What use do you intend this for? I can see it being good for a charge port (xt90, barrel jack, whatever youād use) but loop key? Are you also limiting current in the VESC settings? Wouldnāt want it to blow because you pulled a tad too much current while riding I would think.
I actually do use the same kind of fuse for the charge port:
Why not? Fused loop key makes a lot of sense to me. If it blows, itās easy to replace. When testing, I can carry another loop key in my pocket and not have to push home in case the test doesnāt work out as expected.
I have 50A current limit on each motor. Iām going to add 30A battery limit per VESC as well so that I donāt exceed 60A battery limit total, though I donāt really ever do.
60A for a few secs should be perfectly safe. Thereās padding. Even at 2x rated current the fuse should take a few seconds to blow (according to the data sheet).
Iām thinking of putting on all my protective gear and doing some uphill runs with hard acceleration. Maybe carry the board downhill until I have enough confidence the fuses donāt blow under hard braking current.
I think itās a great idea
I think itās a terrible idea because you can fry your vesc if youāre braking when the fuses blow.
Thatās 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 thereās a short.
So insane, you are always builing different boards, all the way through eskate universe. Most busiest guy ever! Thats awesome,dood!
Lol my homie is out here preaching off of, what?
10s, some hub motors, and 8 miles of range? Lolol
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 Iād 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 didnāt 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. Itās 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.
Now I have to go through the trouble putting the 7" hubs back on adjust the motors/belts change info in Metr Pro. aināt nobody got time for this I gotta R.E.D.
