Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

Thanks a lot for your answer Smeagol :) It gives me a great place to start, and since my battery capacity currentwise will be close to yours, it might even be a good starting point for me. So what percentages did you end up using then, to restrict the current to 60amp cont. and 85amp peak? I will ha...

Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

Nice! It's really good to see you're on the road and enjoying it. I will be in the midst of programming my exact same motor and controller in a few months and might need some of your help... :oops: Dare I ask you what total battery capacity you ended up with, and do you have an impression of what so...

Re: Demagnetized magnet for electronic throttle, help!

I would test it the way it is and see what happens. Soldering temperature is for sure hot enough to demagnetize them though. The orientation of the hall sensor matters. If you have a picture of the other half, we can be more certain about things. I will definitely get up a photo of that. Thanks a l...

Re: Demagnetized magnet for electronic throttle, help!

I was desoldering the cable from the brass piece that the magnet is glued to, so temp was well over 1800 degrees C... :shock: 1800 C :shock: ...i highly doubt that temp, ...but if so, im surprised there is anything left !

Re: Demagnetized magnet for electronic throttle, help!

I was desoldering the cable from the brass piece that the magnet is glued to, so temp was well over 1800 degrees C... And the magnet is completely dead by the "feels of it", but I can try and see if I can get some sort of response from the sensor anyway. The sensor was well out of the way when desol...

Thanks Fechter.. Just updated the thread with a picture.
The sensor sits in the opposite side plastic housing, and unfortunately I don't have a picture of it.

There was a set of screws which had their heads sticking out so much that I needed that green spacer between the brake bracket and the swingarm, but I drilled the through holes in the bracket so it would accept the same type of screws that hold th...

Re: 1970 Vespa 50s electrification project

I never found a more suitable BMS (sizewise) than the 150A version of the one I had, so I just went for that one. It's on its way now, which means I can finally continue on the battery box build. Apart from that, I have been working a little on the swingarm, making all the sheet metal parts for it. ...

In desperat need of a BMS, I will (bump) extend my topic to any suggestions on a 100 to 150A BMS's.

Please, if you have any suggestions, I'd love to hear them.

100-150A BMS that doesn't exceed 65mm width

Hi, I am quite restricted space wise on my battery pack, and for this reason plus aesthetic reasons I would like a BMS that fits within the width of my battery pack (which is the length of an 18650 cell + holders). My chemistry is of course Li-ion, it's 16s, and I would like somewhere between 100 an...

Re: 1970 Vespa 50s electrification project

I need help picking a new BMS.

I sent back the 80A version and finally got my money back. They have a 150A version available, but design wise it would be so nice to have one that is no larger than 65mm in one direction.
Advice is greatly appreciated!

Re: 1970 Vespa 50s electrification project

Slowly making the swingarm on my own. Things are still so busy at work that I can't spare any time going to the workshop for personal projects, but I managed to squeeze in an hour today.
"Control room" is also taking shape.

Re: 1970 Vespa 50s electrification project

Looking good! Maybe consider using a bush on both sides of the axle that fits exactly inside of the rectangular box section of the swing arm. That way clamping/tightening the nuts won't cause the box section to deform. But maybe you were already planning that. Yes I am :) (good thinking) I will als...

Swingarm design is done. I'm not sure if I will wait for the guys at the workshop to have time to do some machining for me, or if I will just send it all to a machine shop...

What I also thought of as an option, but forgot by the time I replied to your comments, is to plastidip the side of the plywood that will be exposed to water and dirt.

Re: 1970 Vespa 50s electrification project

I was going to laquer it inside out, and caulking all seams/joints so water doesnt get into the fibres through the cuts. I haven't been worried at all actually, good quality beech plywood with the correct surface treatment can last a long time in really rough conditions.
