Agree it looks good. I like the copper to reach all the way in if possible and fill the hole more fully w/ solder.
Yea, that was the intent but then while soldering it got bumped up unfortunately. As long as it can pass the current, I’m happy!
Is there a performance or safety difference between using copper and a 12 awg wire?
Not really - for such a short run it should be fine. I would definitely go as thick as you can w/ whatever you use, and keep it as short as possible. That was the main reason i went with the solid copper - because it was direct point to point vs a loop of wire, and strong enough to then tug on w/ the paracord.
The only time i’ve heard of a problem is too thin of wire and a longer loop - more heat under load = bad.
Good to know. My loop key haven’t felt hot after riding so I think I should be good.
Sorry, newbie question. The anti-spark loop key is supposed to go on the + wire, between the battery and the VESC, right ? And it allows you to leave your battery in the board and acts like a on-off switch ?
Yes exactly! If you have a bms and charge port you should put it on the + wire in between the + of the charge port and the vesc. This way you can and should pull the key out when you are charging.
Maybe I missed it in here, but wouldn’t it be more ideal to have the female side connected to the board and use the male portion as the “key”?
Are the male ends Anti-Spark or will have to re-solder the female onto my battery and the male end onto my VESC ?
That’s a good way to do it as well.
Easier to secure the Male portion to an enclosure flush, and if the anti-spark portion of the key does get damaged (not fully seated you will melt the resistor) - a simple regular XT90 (spark!) works in a pinch and you can still ride.
Thanks for the panel mount models, came out great
One tip, after port inserted, heat up the mount for it shrink a bit to the connector, makes it impossible to push out the back even without a screw
Question, would it be possible using a fuse holder, and a 80A fuse as an alternative to anti-spark loop?
You’d still get a big ass spark. The only two viable options are an anti-spark switch, anti-spark loop key or BMS with E-Switch.
This has been exhaustively covered many many time for a couple of years now.
Good tip, I usually just use super glue, never have used screws. But that’s even better as you might be able to heat it for removal as well.
I embedded mine in the deck. I like to use the anti-spark male shape on the deck side as its cheaper to have multiple keys that way. Just in case I loose one. With this on the side of the deck I can access it from the top or bottom in an emergency.
What if you burn out the resistor?
Yeah since its epoxyed in it would suck to replace. How long do these things last? If it last 1000 insertions I would be happy.
Honestly don’t know, I’ve seen people burn them out quick, like weeks-months, though I’ve never burned one…
Ive burned through like 4-5 lol
You are very special
