Great video bought a power supply from Amazon the same that you say in the video and the bike wake up put the original charger in the bike after 10min the charger light turn red and it looks like it is charging You are a Hero many thanks
Insane! Thank you so much, from all videos I found yours is the one which actually works and can do it yourself! First I got a 30V/5A charger but that just didn't have enough power so I changed it for a 64V/5A set it to just below 2 amps and pushed the voltage all thge way up which started around 45 then slowly moved up, after 45 mins it was up to 50v. Plugged in the S5 charger and it started charging, I was able to get the lock off from the wheel, that was my biggest issue if I had to bring it to a service center far away. Now no need for bringing it away for a service.... THANK YOU SO MUCH :))
Great video. I had same situation and it worked. In fact I didn’t have a battery charger so I used an old laptop charger. (Not recommended of course 😂) All VanMoof repair centers were suggesting to change battery etc.. which they cannot even get for two months. Good work!
Hi, what type of adjustable power supply did you use please?, and can you pls, pls, Please ...do a short video on the setting on "How not to do this at home" with the device. My S5 has been DOA too for months, and no store wants to touch it. Thanks
Have a dead S3 battery after parking it for a couple of months. Didn't know that it was not a good idea to do so 😢. Cheers for the info. I presume it the same process for the S3 ?
Hey hey! Thank you so much for posting this video! I think this is going to be the only thing that can save my brand-new S5, which seems to be experiencing the exact same issue. (Brand new, ridden like 10 miles, and now battery is so dead it can't charge to get firmware updates). I live in the States, so I'm even more out of luck than most in getting help from VanMoof. :( I dropped a note on the contact form on your site. Not sure if you got it or not, but curious for any other detail you could provide for a novice. Of what not to do, of course. :) I'm new to using an external DC supply, but it sounds like I ensure it's set to 30 or 35? and then I'm going to leave it connected long enough to watch the amps drop to near zero? Roughly how long was that? Is it like seconds... or minutes? Am I just reading the readout on the voltage supply box or measuring the bike's battery? I went with a generic DC supply from Amazon, like I've seen in a few places, but I'm not sure if I'm actually reading it right. Even if you can't reply, thank you so much for this video. It's already been a tremendous help of giving me hope that this isn't a $3500 useless brick.
Hi! I’m attempting the same and wondering roughly how long this would take. I’m sure it depends how depleted the battery is, but want to make sure I have enough time to regularly monitor the battery temp.
Hi, thanks for another great, common sense video. Can you please recommend a good variable voltage supply - not that I'd ever use it to do that of course ;-)
Honestly I've been using a 'generic' 0-60v 5a one from Amazon, it's about 0.5-0.1v out from what it says, but as long as you know that, you can account for it.
@@EbikeRepairsDumb question but how I know when 31 V are arrived?

@@EbikeRepairs for clarity, you’re connecting the variable DC supply at 35v and .5a and charging long enough to read 31v from the battery pack? i’m assuming you’re using a multimeter to read the DC voltage (after you charge for a bit) at the same terminals you are charging into. thank you- i have an A5 that i resurrected by charging the BMS battery via the debug port. and now the electronics work, but the main battery won’t charge.
Did you guys get low voltage from the connector of the charging socket on the bicycle? I don't see any voltage on this. I also see no voltage when measuring directly on the battery.
