FatBoy antispark 0.5W draw

For reference I think it draws 2-3 uA. So roughly 2000 times less.

Yeah right 3uA xD

Do you store your board at 42V? Facepalm.

I said my 10s3p got drained to 0 in 2 weeks. No where did I state that it was from a full charge because I sure as hell don’t store my boards at full charge.

Edit: I have over 10 boards and hence store them at 60% charge for each to preserve battery life. It is obvious that there are times where I neglect riding some boards for weeks or months at end, and having a passive 0.5W drain isn’t ideal. I can’t imagine being alone in this dilemma. I’m sure there are some who are sesonal riders and don’t ride in the winter.

It’s not a matter of whether it consumes power, it’s a matter of how much it consumes and what an acceptable limit is.

I store my board at 240V does it matter?

Whatever floats your boat.

Sorry checked datasheet, 9uA. My mistake. So just about 1000 times less.

Well the switches are different in the first place but ur switch aka unity still wasn’t delivered since last autumn…

  1. The first batch of Unitys have been delivered. I own one.

  2. That isn’t the point. We’re merely pointing out that a drain of 0.5W is too high on idle. If you don’t want to anything about it, that’s fine.

Side note, your attitude regarding this matter is really off putting. I find you constantly critizing designs of others (e.g. flipsky), but when someone brings up a concern on one of your designs, you get super defensive. Not cool.

Edit: i don’t think this is the right place to address this particular concern. I’m sorry @goldenHusky for de-railing your thread. If a moderator could kindly address this (either by deleting the messages or moving it to a seperate thread, that’ll be most appreciated.) @anorak234 @mmaner @treenutter thanks!

Well I’m glad I clicked on this thread. 0.5w passive drain for a power switch is worthy of notice when purchasing especially on what would be considered a high end item. Draining $300 packs dry in a month is way no bueno. I have a couple of these for future projects, and certainly would have made sad and angry faces at some point had I not seen your post.

Thanks @nuttyjeff I consider your post a PSA.

@Kug3lis you owe your customers better. At least a warning. It’s hard to continue to support your products if you don’t share stuff like this.

@goldenHusky sorry for cluttering your thread. I’m excited to see the pre-charge circuit. I wasn’t sure if I was being dumb when I made this post

EDIT

Adding some math. 0.5w at say 10s fully charged is .5w/42v == 0.012a. 4p 30q pack is 3000mah*4 == 12ah. 12ah / 0.012a == 1000hr. 1000hr / 24h = 41.67 days to drain down to 0% (about 6 weeks).

I’m afraid this forum needs a new rule against “customer bashing”, can’t believe these rude words.

@nuttyjeff I just checked the voltage on my 10s4p with connected standard vedder antispark switch. I didn’t ride the board since 5 months and the total voltage decreased max. 0.2V - 0.4V, could be even less.

On my MTB I have a 3way directFET antispark switch from @goldenHusky (I pull up to 100A on 12s, works great) and I didn’t ride for 2 months, too. There is no noticeable voltage drop (maybe 0.1V or less).

That’s the first time I read that an antispark switch drains a battery within weeks. This is very bad and should not exist.

For people who use these as tools and not toys, boards get stored “charged”. Do you store your car with all the gasoline drained out? Fuck no… because you might need it at any moment…

So if a system can’t be stored at full charge, then it’s defective for my purposes. A car that couldn’t be parked with more than a half-tank would be defective also.

Sure, if a board breaks down I won’t charge it until it’s repaired. But to suggest that storing these uncharged is normal or correct is hilarious. I don’t make these to look at, I make them to ride.

I store most of my boards at 60% simply because I have alot of them and storing them at full overtime damages the cells. (Correct me if i’m wrong). Would you then advise me to store them all at full charge…?

As far as I know, cars can be stored at a full tank of gas or half a tank without any detrimental effects, the analogy falls short there.

If your boards aren’t ready to ride, then they are toys.

When you use these as transportation, you will understand.

It’s no different than having a car that takes 3 hours to start. It’s not practical. If a battery can’t be stored full, then it’s a shitty battery. Shitty batteries exist. Maybe that’s one reason I like LiFePO4.

Storing a board at 60% makes it unridable? I dont get it.

I don’t understand what to share? How the fck do you expect a device to stay in stand by mode and listen when the board starts pushing or momentary button is pressed and turn everything on, not the latching switch which turns on everything and keeps the power on but is dumb as fck as it doesn’t have any logic at all. Yes, I could have made it eat no current at all, but would you pay a few times more for it? No, you would all cry how it is super expensive and shit. Efficient parts dc/dc converters and etc cost money, and you guys always complaining that everything is expensive so for god sake please don’t cry.

I am not sure but every switch which uses momentary button and something like PTS will have the same issue.

Well, good thing I stopped making new stuff for this forum as no one in this forum even appreciate people doing hard work to make something good for this community, just fcking bashing everyone around and complaining about every fcking single bit. This community went from super innovative and creative to let’s find another issue and bash someone about it.

It’s latching switch there shouldn’t be any drop at all…

Well if it should not exist then I can just stop selling it because I am not going to spend any more hours of my precious personal time to create stuff for the community who doesn’t appreciate anything. Don’t forget esk8 DIY market is not thousands of customer but at least a few hundreds, and all those purchases not even compensate for the time people spend innovating and creating products for this community.

No wonder people are leaving this place. You can consider me switching off pretty soon too, as I am not going to share my thousands of hours of programming and designing on ESC with this community which will just find another thing to complain about.

I don’t know the previous history why you think like that. I’m sure many people appreciate you hard work and like your products. I personally never had items from you but I’m sure they are good quality. And you had a title :wink:

I heard your switch is reliable, didn’t know it starts when pushing which is great. I think the main point is that customers should know about the fact that they MUST disconnect the battery e.g. in winter break. I just imagine someone coming back home after 3 weeks holidays and the battery is dead :unamused:

oh @Kug3lis , why so angry? just understand our site too. we are no engineers and don´t understand things like that. how can we know how much energy your switch use on standby? … I should now start to research data sheets of components you used? come on… not really please. Is it a big problem to add a small notification on your website? one sentence “disconnect from battery when not charging for more than 2 weeks” and you save out of any claims. If people don´t read it, it´s there problem.

I´m sure people appreciate your work and the work of your paps. you can read it here multiple times! It´s up to you on which comments you set your focus. There always fanboys and hater. That´s not only in this community. You created what you think is how it should be with all your products. If other people don´t like it or say something about the design than you can just ignore it, or have a look if there is some truth in it and you can improve your product. No need to get crazy about it.

That´s very true words, but you wouldn´t be here if you wouldn´t enjoy riding. Maybe things changed in your life in the past month, but don´t tell us you spend all your free time just to create products for only us. you made it for you too. because you was not happy with what you could get on the market and wanted to make it better! Nobody force you to do anything for us here. It´s your free decision what you are doing with your free time. always!

@goldenHusky sorry for that and @mmaner or @anorak234 it´s really time that this topic is split from the original post.
