April 28, 20241 yr Has ebay come up with the goods? https://www.ebay.co.uk/itm/384195108347?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=illlzdgktg2&sssrc=4429486&ssuid=IB4nVD07Rea&var=&widget_ver=artemis&media=COPY Everything on my bike is 36V. My searches have so far, have not hit paydirt.
April 28, 20241 yr I doubt they'll engage like that. Why risk digging a deeper hole for themselves? Very interesting, I'll attempt finding MCBs on AliExpress suitable for ebike use. It's their chance to show what kind of company they are. I hope they do sort it. As it is, I'm left looking like an idiot as I recommended Yose power to my friend who bought the battery in the first place...It would be nice to be able to recommend a company without it coming back to bite you. Be careful with these resettable circuit breakers from Ali Express, eBay etc. I have had some in the past and they have not done their job and cut power, or mechanically, they have fallen apart. Buyer beware...
April 28, 20241 yr Be careful with these resettable circuit breakers from Ali Express, eBay etc. I have had some in the past and they have not done their job and cut power, or mechanically, they have fallen apart. Buyer beware... Well that's just marvellous. I'll probably solder three fuses in series, to increase the odds of one working.
April 28, 20241 yr It's their chance to show what kind of company they are So they are a company then ? and not a branch of the Chinese government and Military as seemed to be implied in earlier posts.
April 28, 20241 yr governments are corporations lol ,well ours are anyway registered at dun and Bradstreet
April 28, 20241 yr So they are a company then ? and not a branch of the Chinese government and Military as seemed to be implied in earlier posts. You clearly haven't read and understood my posts properly.
April 29, 20241 yr Author 1. We are currently discussing technical issues and we do not post or respond to any comments about national discrimination. 2. The author's title and content are sufficiently misleading. Our products have sufficient patents to prove that they are different from UPP batteries, and there is no official information that Yose Power’s batteries have been recalled. 3. We are a professional electric bicycle battery manufacturer since 2011, our products have undergone strict testing and passed CE certification. 4. Technical Description: Teflon wire is a kind of wire made of polytetrafluoroethylene (PTFE), which is widely used in various fields because of its excellent high temperature resistance, corrosion resistance and insulation properties. Heat resistant temperature. Teflon wires can withstand temperatures ranging from -180 ° C to +260 ° C; The maximum carrying capacity of the 2.5mm² Teflon line reaches 48A; And it can withstand 50A power for some time, so we are equipped with a 50A fuse. When the current reaches 50A, the fuse will disconnect the protection circuit. This is a technology fully recognized by our engineers and engineers from testing and certification agencies. 5. Rights Statement: We appreciate and accept suggestions from everyone, but when some non-professional technical explanations appear in public channels, we also have full rights to explain and protect our brand rights.
April 30, 20241 yr Thin Red Wire: The wire mentioned in the post is a Teflon wire, specifically designed for its exceptional properties including high temperature resistance, corrosion resistance, and insulation capabilities. Teflon wire is known for its durability and reliability, and it is highly unlikely to cause the described phenomenon. The wire can withstand extreme temperatures ranging from -180℃ to +260℃, and its maximum carrying capacity is 48A for the 2.5mm² size. Therefore, the concerns raised regarding this wire are unfounded. 4.

How hot does this thin wire become?
April 30, 20241 yr 2. The author's title and content are sufficiently misleading. Our products have sufficient patents to prove that they are different from UPP batteries, and there is no official information that Yose Power’s batteries have been recalled. There is free speech and irresponsible speech. It's a fine line to tread. I think I have made my point...and I am not silent. Could you upload the recall message?
April 30, 20241 yr Just my opinion and therefore probably not worth a lot, but I don't think this discussion is leading anywhere useful. The measure of a battery / electric motor company in my opinion, is whether or not most people are happy with the product they receive for the price they paid. I have no personal experience of the products of this company, but as far as I know, people like them and think they have got what they paid for. I would suggest, that unless a few of us have had really bad experience of buying and using these products, continuing to whinge on and demand information is probably harmful to a company producing a fair deal for its customers and working hard both to make a living and to sell useful products to the satisfaction of buyers. If this is not the case and numbers of people have had bad experience, say so. Otherwise - let's stop bitching about them.
April 30, 20241 yr Has there been a recall? If so it's important to know why, don't you think? Edited April 30, 20241 yr by jamesporritt
April 30, 20241 yr Has there been a recall? If so it's important to know why, don't you think? Lilly says: "They are different from UPP batteries, and there is no official information that Yose Power’s batteries have been recalled."
April 30, 20241 yr Lilly says: "They are different from UPP batteries, and there is no official information that Yose Power’s batteries have been recalled." I'm capable of reading, thank you.

User safety is more important than sparing the tender feelings of any company.
April 30, 20241 yr Has the identity of [uSER=45787]@Lily-YOSEPOWER[/uSER] been verified? Has anybody's ID been verified?
May 1, 20241 yr Has anybody's ID been verified? Mine hasn't. I'm not really a gigantic 6'3" 15stone Glaswegian. Im really just a fluffy bunny.
May 6, 20241 yr The main fuse was 50A and the BMS was a high current rating too. If someone had drawn more than about 25 to 30 A, the wire would have melted through the insulation, quickly melted through the PVC insulation on the cells, and then shorted out all the banks from one end of the pack to the other. Thin Red Wire: The wire mentioned in the post is a Teflon wire, specifically designed for its exceptional properties including high temperature resistance, corrosion resistance, and insulation capabilities. Teflon wire is known for its durability and reliability, and it is highly unlikely to cause the described phenomenon. The wire can withstand extreme temperatures ranging from -180℃ to +260℃, and its maximum carrying capacity is 48A for the 2.5mm² size. Therefore, the concerns raised regarding this wire are unfounded. Tape around Battery Cells: The tape wrapped around the battery cells contains fiberglass and is primarily used for wire organization and securing purposes, rather than for protecting the cells themselves. Several people have asked several times how hot this wire will get. We haven't seen hard evidence that it gets too hot (an "actual problem") and we can't expect engineering answers from customer liaison. Still it's a bit worrying that Lily-YOSEPOWER's response has been the opposite of what you'd hope for. Presumably Teflon has been used to save space or because this wire does get hot, and indeed the photos make the gauge look around half as thick as the black BMS connection (making several times the heat). But if it gets hot you'd want to re-route it or run multiple strands to keep the temperature down, especially as the photo shows it running against the cells and YP say (2) their tape isn't for protection. What we least want to hear is about how the insulation withstands 260℃ and the wire's thought to be good for 48A (probably rated at around 70℃ to 130℃), because the cells have an operating range up to about 45℃ and once breakdown begins from around 60℃ it can soon turn exothermic. Regardless of any confirmed problem or not, with a battery this size if things look questionable it makes sense to point them out, and it's good that YP are here now to respond.

May 6, 20241 yr Wow... Have Woosh and Wisper been verified? Just checked in the bathroom mirror and it’s definitely me! All the best, David
May 6, 20241 yr Wow... Have Woosh and Wisper been verified? we were sent a questionaire around this time last year by the office of product safety and standards. I filled in the questionaire, attached conformity certificates. Didn't hear from the OPSS since.

May 6, 20241 yr See here: Official Announcement Hi Lily Nice to have you here. I hope you will stay. For a long time I have been recommending Yose Power for beginners who want to convert first bike. I am using one of your kits myself and think it offers great value for money. Having that said in my opinion Yose has very little to offer for more advanced enthusiasts like most of people on this forum. Is there a chance you might expand your offer? There is a big gap on the UK market at this moment. By expanding offer I mean more motors from manufacturers like Bafang, Tongsheng, Toseven etc, spare parts, kits with KT controllers and last but not least batteries with better cells. Kind regards Unverified Az
May 6, 20241 yr Wow... Have Woosh and Wisper been verified? I met Helen and Scott in 2013 at Redbridge.
