This helps a lot. Thanks. _I_ have now done this: 1. Online search for an SFK -4045A. I ordered a pack of 10 from China. 2. Searched for an SFK -4045A schematic so I understand what I am working with. 3. Photographed the battery orientation so I know how to put it back in. (Hey, if you don't know where your tweezers are then I will not notice how the battery was located.)

hello, the fuse was blown. but I measured 41 volts between pins 2 and 3. I'm hesitant to put the fuse on to solder. Pin 2 is supposed to be something like a thermal protector. but the 41 volts worry me. thanks for the info
hello thank you for your video. i dont know much about soldering and multimeters but i'm gonna try this fix! i ordered some chips, now in the video at 11.50 you say all tree points should be open lines. what setting on the multimeter should i put and what do you mean with Open points?
Excellent video - thank you so much for all the work you are putting into this! How did you diagnose that the fuse is the problem and not some other BMS-component or one of the cells? Or is the fuse basically always the problem?

Hi there, I see you reply to all the messages in the description :-D so here's my chance.. I've ran in an issue where the bike stopped assisting, the torque in the motor stopped. So I checked the wire harness and successfully replaced it with a new harness. Now I have a error 20 shown only when I reset the cartridge.. looked online "No battery output". and still the issue that the motor doesn't have the power the drive a human on the bike, only up side down it spins the wheel, putting your hand on the wheel to create some resistance, it can't handle.. Do you have an idea of route me to some thing I can check on the cartridge, motor, battery? - motor spins - checked the fuse on the battery Thanks!
the trick is if a tool is not in your hand, it should be put back in it's place. doesn't matter if you have to walk more, either in place or in the hand. no exceptions. you'll save time in the long run with this method, not to mention sanity
There have been smarter minds thinking about this before. Especially @ Toyota with the lean manufacturing principles. One key method you might want to look at is the “ 5S method “. It describes how you keep your workspace in a good shape and continually improve it.
I have weird issue, at least I think so.. :) My vanmoof s3 shows 6/20/17 so prob the battery fuse blown, had the the battery changed for refurbished one and worked fine until I needed to charge. Again the error 6/20/17, error 17 is also shown in app. Then after few days all is working again, can ride the bike like nothing is wrong. Then I charge again and same story... Any ideas what I can do?
On my s3 i had error codes 6 20 and 21 after that the battery was completely dead. Now i have changed the charger to the lower amp setting. There is now a sign of live but it will constantly trip between charging and showing error 6. Each after 2 min it makes a loud noise but it will never be connceted to the app or even work. What now?
@@Razspareparts if i get a battery replacement of replace the fuse, and i going on from that with the lower amp charging. Im never get this problem? And im never going to seer error like 6 20 and 21?
@@Razsparepartsi saw that the fuse is ok. No burnd components but still make err 6 if i put the charger in. Ive i plug the charger in without the battery inside i can use the smart things like change the light mode and switch gear settings. What now?

Lol .... I have them hanging on my neck now 😂
can i desolder the chip with a regular iron? or do i need one of those flame thingys
Hi Raz, this is perfect. Can you also repair the battery of the vanMoof S1 (E29). I really appreciate your help.
Thanks for video, you help a lot 😃, can you show us how to fix the cause of the 3 blown 151 transistors?
