I have not used BMS Battery and can't vouch for them.My understanding is that when you order you need to specify the battery chemistry (e.g. lead acid) and they will customise the charger to match it.

My mistake, I'm pretty sure that the cells in my battery are of the inferior variety so I have decided to play safe and go for a 2A charger. I have followed your lead and gone for a metal cased one, with a fan and a fuse on the output made by AnnPower. It claims to be CE compliant but we will...

Hi Douglas, I used to be a fairly dab hand with a soldering iron and am reasonably confident in building a charger (though I've not had much experience of surface mount components and multiple layer boards). I am not up to designing one. Where would I start (kit or pcb template to photo etch)...

Thank you, That fits with the research I did this afternoon. I recon I am much better off with a good quality Li-ion charger at 2A than trying to use a power supply. I've read in a few places that the charger needs to be tailored to the battery (i.e. not all Li-Ion cells use the same charge...

Thanks, I guess the other alternative for local use is to charge fully but not re-charge until the remaining charge is too low for the next journey so I reduce the number of charge cycles and fully charge each time. Or I could do both :-)

Brilliant, now I understand, my charger is welded/glued together which is why I was a bit confused. Thanks

Thanks, how did you know where to drill the holes and how did you aviod damaging the internals when you drilled them? Best regards, Robert

Thanks, I like the idea as it would also double up as a bench power supply. I haven't got my head around exactly what CCCV means. I am probably being a bit dim! Does it mean fixed voltage and limited current (i.e. 42V limited to <= XA)? If I use a power supply as a charger I assume that the...

Thank you both, The reason that I am uncomfortable with the plastic case charger that I have is that the case gets up to 75 degrees C. It works perfectly and is really compact and lightweight to carry but I don't have any confidence in any device that appears to be running under that much...

Hi, Please can anyone recommend a reasonably priced quality charger for a 36v 20ah pack. In an ideal world I would buy a Grin Technologies Satiator but they are pretty expensive. There seem to be loads of cheap plastic chargers out there that I would not trust. Ideally I am looking for a...

Thanks, I don't have a problem with the click, my worry is that it may be a sign of a fault that could deteriorate. I want to use the bike for long distance cycle touring so reliability is high on my list. One of the reasons for choosing the BSS01 was that if it does break I can swap it out for...

Please can anyone help with the clicking noise that my motor is making when I turn the pedals. I have started a thread in the technical forum: http://www.pedelecs.co.uk/forum/threads/bafang-bbs01-b-clicking-noise-when-rotating-pedals-by-hand.32433/#post-456412 Best regards, Rob

I took the cover off this afternoon and the click is definitely associated with the gear wheel that drives the chainring (crown gear?). I can't be sure but it sounds like its originating from where it meshes with the nylon gear from the motor. The two do not mesh as closely as I was expecting...

Update - I still have to dismantle but spent a few minutes investigating further: There is no play as far as I can tell in the bottom bracket and the bearings seem to be smooth when I rotate it in forward and reverse. Turning the chainring so it drives the motor does not result in any...

Building a Kona Minute Bafang BSS01/B - All help and advice greatly recieved

Hi, Definitely not the pedals as it happens when you rotate the cranks without touching the pedals. Rob

Hi, I have just installed a new BSS01/B from China and the pedals make two clicking noises each revolution they are not at 180 degrees apart and the position moves if I rotate the pedals backwards (suggesting to me that it is not the bottom bracket bearing as it would be in the same spot?)...

Hi Michael, I'm not sure if you are still active on the forum? I have just installed a brand new BBS01/B which has exactly the same "fault" as yours and ticks in the same places. Did you ever get to the bottom of the problem? Best regards, Rob

Thank you, you have saved me from making the same mistake. I rode the bike unpowered today (don't have a battery yet) and its OK on the flat with less resistance from the motor than turning it by hand would suggest. Any tips on spiders that I could use to move the chain line 4-5mm closer to the...

Thank you all for the helpful advice. I installed the motor today and tested it with 3 lead acid batteries in series. All seems to be working O.K. https://photos.app.goo.gl/7fmEp1gaMWDYQHve6 I've ordered a cheap 20AH battery to see how many miles I get. Once I have a better understanding...
