Re: 10kW stand-up scooter with air suspension

What??? You've spent more than 30-40 hours to create the version 1 and also you've built a new battery pack! How could you sell it so easily? If the difference will be only the new motor then you could just change the motor.

Re: My battery building business...need your help

Hello, I was in Israel for four days. Three in Jerusalem and one in Tel Aviv. The reason I am writing here is because I was impressed of how many e bikes and electric scooters you have!! I haven't seen so many electric vehicles in my life before. The most of them are low power ebikes from 250 up to ...

Re: 10kW stand-up scooter with air suspension

I can see clearly that at your last two videos you were driving much more carefully. Bravo!
By the way why have you installed the extra black-red handlebars ?
Are they to carry a child ? To carry your shopping maybe or to rest your feet when they get tired ?

Re: Qs205 getting hot after hall sensor replacement

check this guy from Poland, he can rewind your qsmotor with more cooper for maximum performance.

or you buy a new one with a working temp sensor this time and you won't have the same issues.

Re: MaxE died while charging....how to test?

Good morning! What has happened finally with your MaxE? My midi-e failed last week while I was riding, I was lucky that I wasn't going very fast because it has blocked the motor. I think some of the mosfets are dead because the battery cables have shorted out. Do you have any idea if we can install ...

I hooked up with Pat at Sportsman Flyer (https://sportsmanflyer.com/) and worked with him to put together an electric version of the gas repros he makes. The ebikes aren't on his website but are available if you reach out to him. He has tons of pics on his Flickr here (https://www.flickr.com/photos...

Re: Looking at building a new pack with Samsung 50E

@icherouveim, do you know how likely the 40T cycle life will be similar to the 30Q's? I'm not happy with how my 30Q pack lasted. I definitely don't want to build a new pack with cells that have a cycle life profile similar to the 30Q. With simple maths: For 30Qs you have maximum named current 7P x ...

Re: Qs205 getting hot after hall sensor replacement

its a very big mistake for a high power ebike not to have a working motor temp sensor. Maybe the characteristics of the windings have changed because of the high temperatures and you don't know. With the hand you can't really know the inside temperature.

Re: Looking at building a new pack with Samsung 50E

I agree go for 40T cells. I am going to use them for my next battery pack. At the moment I have a 20S-9P made by 30Q cells, still works but it sags a lot and my concern is that it doesn't have lot of cycles. Generally speaking 30Qs cycle life is very poor. let's hope 40T will last longer. So there i...

Re: Qs205 getting hot after hall sensor replacement

When the motor gets hot then you should have overheating protection and not over current that can mean two things. if you were not monitoring your motors temperature at the past not to be more than 140C then maybe the windings have started to fail melt down and the resistance is lower so it's harder...

Does the motor work more efficiently and at lower temperatures with this controller?
