October 31, 20232 yr Author 15A drawn by the controller won't destroy it, but a cheap Chinese battery's cells will be quite stressed, compared to say LG MH1. My battery's BMS is 22A, but I could replace it with a 30A BMS, if I need amps for yet more additional lights, electric blanket and beer fridge. Ah ok, understood
October 31, 20232 yr Author Which LG cells specifically? The forum battery boffins will be able to advise. That's one question I didn't know to ask back then... I had to open the battery to find out over a year later. If the battery fails, how do warranty repairs work? Before the sale my Chinese seller told me he had "Diagnosticand repair facilities in Europe", but after the sale it turned out everything had to be posted to China. LG 18650 3500mAh The BMS max current is 25A Edited: I sort of presumed unless I bought from a reputable UK based seller that you are on your own with repairs/warranty.
October 31, 20232 yr Additionally I was hoping to buy a bbs01b with the gear sensor option and I read that your selling with model without that? there is a large existing supply chain for Bafang BBSes, so there is no point for me trying to compete with Ali, ebay and amazon sellers. You can get gear shift sensors on Ali for about £10 or £20 on ebay. The main thing dealing with UK established dealers is the support should you ever need it. You don't have to wait for emails to go back and forth to get your bike back on the road, not just under warranty but also after that. We routinely give links to where to get stuff that we don't stock.
October 31, 20232 yr LG 18650 3500mAh Which LG 18650 3500mAh cells specifically? Whichever, personally I'd buy LG instead of cheap Chinese celled any day. I don't know which delivery services would deliver a faulty battery to China, or how much it'd cost. I sort of presumed unless I bought from a reputable UK based seller that you are on your own with repairs/warranty. Batteries are expensive to replace of course, best aim to get it right first time.
October 31, 20232 yr If money is tight, perhaps you could consider TSDZ2b? You can get it from UK source for around £200.
November 1, 20232 yr Only place I would shop did my 2 bikes https://www.cogsygogs.co.uk/ [ATTACH=full]54873[/ATTACH][ATTACH=full]54874[/ATTACH] Is this your battery? https://reddragonebikes.co.uk/shop/36v-20ah-lg21700-5000mah-10s4p/ If so, do you know which LG cells are in your battery? The web page just says the cells are "LG21700-5000mAh", without naming the specific LG cell used. I'm not encouraging you to open your battery to look.
November 1, 20232 yr instead of buying the BBS02B from Ali or from EU, you can get the BBS01ET from me! No need to wait a week or two for delivery, no worries about road legality. I also have 48V batteries with Panasonic 21700 cells to match. https://wooshbikes.co.uk/?cdkit Your price BBS01B + 36V 20AH DP battery kit and cBBS01B + 36V 20AH DP battery kit and charger £839 harger Really !!!! I paid less than that, colour display and FITTING from Cogs Y Gogs
November 1, 20232 yr I think it a shame companies can advertise here it makes for a totally BIAS forum
November 1, 20232 yr I think it a shame companies can advertise here it makes for a totally BIAS forum As long as the advertising is clear (as it is when you see 'trade member' discussing their own bikes) it makes for a broader set of opinions. Of course, as with any forum or review site, you need to interpret every post carefully.
November 1, 20232 yr Author Is this your battery? https://reddragonebikes.co.uk/shop/36v-20ah-lg21700-5000mah-10s4p/ If so, do you know which LG cells are in your battery? The web page just says the cells are "LG21700-5000mAh", without naming the specific LG cell used. I'm not encouraging you to open your battery to look. This seems to be normal in the UK. Can you name any UK sellers that do specify the specific cell used? I think eclipse do (who are sourced by em3ev) but they are out of stock.
November 1, 20232 yr This seems to be normal in the UK. Can you name any UK sellers that do specify the specific cell used? I think eclipse do (who are sourced by em3ev) but they are out of stock. The Chinese seller on Amazon I bought my kit from, repeatedly ignored that question. I reasoned if they're genuine LG, how bad could they be? Turns out my battery is pretty good. With a noname BMS.

November 1, 20232 yr Who do you think funds the site? Limited sellers on a site mean non diverse bias comments, buy from me what I sell is best, sorry, no

November 1, 20232 yr I will say I have had that fitted to BOTH my bikes, and I would never look back, the drive is amazing. I have however taken precautions in wet and winter
November 1, 20232 yr https://reddragonebikes.co.uk/product-category/bafang-motors/ seems a decent deal on batteries there, and you`d be buying `local` https://reddragonebikes.co.uk/shop/52v-20ah-lithium-ebike-battery-lg21700-new-and-a-grade-cell-5000mah-14s4p-ebike-batteries-uk/ 52v 20ah.

When I desperately was looking to buy a BBS01B kit from a UK based seller shortly before the Brexit date in December 2019, I couldn't find one. Now they are apparently sold in Wales, with fitting available and batteries containing mysterious non-specific LG 21700 cells. [mention=6303]Woosh[/mention] is more visible on Google than he used to be. Everything I've ever bought from my local bike shop has turned out to be total rubbish. Edited November 1, 20232 yr by guerney
November 1, 20232 yr . @Woosh is more visible on Google than he used to be. when covid arrived, I stopped advertising on google. Bikes simply sold fast. I have restarted advertising 3 weeks ago.
November 1, 20232 yr when covid arrived, I stopped advertising on google. Bikes simply sold fast. I have restarted advertising 3 weeks ago. I never see Google's ads, you weren't there on the first two or so pages of organic listings. Good job too, I'd have ended up buying a hub drive which wouldn't have worked out well, because of the work my bike ended up having to do. Edited November 2, 20232 yr by guerney
November 1, 20232 yr I think it a shame companies can advertise here it makes for a totally BIAS forum I don't think this forum is biased. In fact I have noticed sellers get really hard life here, especially at the beginning. I assume Woosh survived similar baptism by fire.
November 1, 20232 yr Actually it is harder this year. Wages go up, energy bills go up, people spend less and search out more for sales and special offers demand is stymied by fire stories in the media. The value of the Pound is lowest since 1985. The only thing that's better is container cost is quite low. Felixstowe port and haulage companies charge me more to deliver my container than the shipping company charge me from China to UK. I wouldn't start a new ebike company in today's climate.
