Interesting. Can you give examples about when he's been dangerously wrong?

I can't recall particular instances but I've seen the same before. FWIW he's getting less stuff wrong over time.

  > FWIW he's getting less stuff wrong over time. That's hopeful, with that kind of following he has some serious responsibility. At the same time, I cringe when I see people working with large packs on workbenches with loose metal laying around, totally irresponsible pack geometries where balance wires cross and recross each other with abandon, recycled cells that have visible external damage and so on. Youtube is a great way to pick up some 'worst practices' thinking that if these youtube stars are doing it it must be ok.

  Like what?! Can't any of you people backup your claims. It's just empty complaining on this site without evidence. It's driving me nuts. Show me what I said or have done that was wrong.

    Mate, I've been following you for a while and have a generally positive opinion of you. I think you're not going to have a good experience coming here with your guns out. I watch all your videos, but wouldn't I be a fool if I just absorbed what you say as gospel? You don't do this yourself, don't you? I'm happy for you and your success and I'm very happy there are people out there like you changing their life outcome out of sheer will, while providing the community with unbiased product reviews and independent tests. Please don't take the criticism as a personal attack. Unfortunately, I just don't recall which information you said at some point that made me cringe. Like I said, I've watched a lot of your videos and haven't had any cringe moments like this for a while now. EDIT: also fyi, this website has an automated banning process if you're a new account with too many downvotes. Unfortunately, the few messages you've written have a confrontational tone that usually attracts a lot of downvotes. If you care at all, may I suggest that you avoid that tone/style. I'd love if you posted here in the future. Take that as you will.

      No of course not, I just see people on this site stating to use recycled NMC cells that are capable of burning down their house with one wrong move, then saying my videos are dangerous. I cover safety all the time, more so than any other channel I know. I do not understand why people are saying these things. I work very hard to make my videos, and people here on this site who do not understand batteries are trying to criticize me. It really makes me mad. And thank you. Just figured out the automated banning process and am using a VPN now. I just want to respond to people, and I hope they can provide evidence of when I did something dangerous. Or said something wrong. And yes, I see what you mean about the downvotes. I am very upset right now because I could argue every point made against me here. I also allow people to criticize whatever they wish on my forum, so it makes it hard on this site where I am instantly censored if I get downvotes. It is very frustrating.

        Just a tip that while HN looks like reddit, it's not reddit. And deliberately so. E.g. you can't downvotes responses to your own comment. This to steer into a different type of conversation. I can't say I've fully internalized it, but it does make for much less shitposting compared to reddit. The downvotes i don't think are due to disagreement or even anger. I understand your frustration (especially since the critique is so unspecific), but i believe the downvotes don't mean what you think they mean, and it's not personal.

        Instead of being 'seriously upset' you could ask yourself if posting this kind of stuff: https://www.mobile-solarpower.com/diy-beginner-friendly-solar-generator.html https://www.mobile-solarpower.com/diy-beginner-friendly-sola... Is going to bolster your reputation as safety conscious or harm it, besides your general attitude in this thread. You are quite clearly advising people to copy this design, you make money of them doing so. Even a one-off should be better designed, let alone something intended for duplication. I had you down as well meaning but a bit out of your depth at times, let's just say that that didn't improve based on the interaction here and your various comments.

Sure, but I will have to go through a couple of months worth of youtube history, I was binge watching anything about Lithium Ion when I was working on this: https://jacquesmattheij.com/long-range-ebike/ https://jacquesmattheij.com/long-range-ebike/ As a result I have a very long article on Lithium Ion battery safety and pack construction in the works, but exactly for the reasons the GGP lists I'm pretty careful about releasing that, I want to triple check everything before putting it out there to ensure that the net result is a positive one. Also: I don't like the youtube format for stuff like this. It would be far better to have these things as blog posts rather than as videos, that would make them much more searchable and easier to annotate. But just to give you two memorable items: at some point Will shows himself working with naked steel tools on a massive, fully charged, unfused battery pack. Just one wrong move or a dropped tool and the carnage would be substantial. That shows to me that he may have good theoretical knowledge but doesn't really know all that much about working with this stuff in practice and how to do so safely. In another video there is a whole slew of balance wires coming out of a pack, crossing and recrossing with abandon. Balance wires are usually not fused, the wires rubbing means that if that installation were for long term use that eventually the balance wires would short out and if you're lucky it would just result in a balance wire evaporating, if you're unlucky it would start a fire right next to a massive Li Ion battery, something that you really don't want to do because of their thermal sensitivity. The risk is that the whole pack would ignite and good luck putting that out. I went to the ETS in Amsterdam, a school for electrical technicians, mid level. The one thing that was drilled into us over and over again during the practical parts of that education is that in the electrical world there are young safe technicians and young sloppy technicians, but there are no old sloppy technicians. Will is still young.

  I had commented to this affect on his channel and my comment was removed. Same with other channels where people are drilling without hand and eye protection.

    I usually always wear eye protection. YouTube deletes comments constantly. And leaves the spam comments. Have you not used YouTube in the last ten years? I can't stand it
