Only place to buy in my opinion. I bought 305 30Q cells and took about a month to get. NO ONE offers a better deal right now, NO ONE!

The total power handling is thus a theoretical 1/64th more.
I'd go with a 3T personally, and keep the voltage lower. But I also like a more modest acceleration, so feeding the 3T more amps isn't a priority for me.
Just my $0.02.

Side covers been modified.

I can offer just completely modified motors for 420euro. 4x15 and 3x19 winding. lead time is 1-2 weeks.

The 3K-Turbo, upgrades the axle from 17mm to 20mm diameter on the wire side with a larger bearing to squeeze in 5.26mm² phase wires
In other league. Kelly is worth about $50 (unit price when ordering 15 pieces). My 5 year old son has KLS7230s on this modified Oset and it gets warm on his usage. I could not imagine using it myself.cwah wrote: ↑Jun 07, 2018 3:18 pmI already have a Kelly controller kls7230s.

Offroader wrote: ↑May 27, 2018 9:54 amI just wanted to give an update about my 40mm EDF fan in my MXUS 3000 Turbo hub motor. The motor is ducted using silicone to direct outside air through the coils. The side cover of my hub motor has holes drilled into it.
I can say that I've ran it the whole last summer, and am running it this summer without any issues. When the weather is hot outside and around 90F degrees, this is the time I like most to ride my bike and also the most difficult times to deal with motor cooling, I am pushing the MXUS motor hard at 8000KW for a very long time with my large 3 KWH battery. I ride extremely hard with only using full throttle.
The silicone ducting I made directly on the coils and aluminum stator has held up without any issues.
I can adjust the speed of the EDF fan and with the very hot summer days I need to turn it up to 80 watts (this is what the 12 volt power supply draws as read on my Max-E) to be able to drive my bike as hard as I can with any risk of overheating. The great thing is I run this 40mm EDF at these high speeds for my entire 1-2 hour bike rides without any issues. This tiny EDF is very reliable and very powerful also at moving air. When this tiny EDF is using 80 watts it is spinning extremely fast, if you held the fan at arms length away it would feel like sticking your head out of a car window driving on the highway. No computer fan would even come close, these fans are used to fly airplanes at very high speeds.
The noise isn't too bad but it isn't silent. At a speed above 15MPH you won't hear it over the wind noise. You do get used to the noise, just like you would the noise of your car, you just don't notice it. The great thing is I can adjust it by reaching back under my seat, so if I want it silent I just turn the knob and I can do this while riding also.
I'm going to finish my Cromotor wheel build to compare this to FF and hubsinks soon. I want to do a direct comparison to see if its worthwhile to do this kind of fan cooling when a more simpler solution is available.

Cwah, how long have you been reading these forums? Surely you of all people have learnt by now the KISS principle?cwah wrote: ↑May 30, 2018 5:46 amHello
Here is my full suspension cargo bike:
https://www.dropbox.com/s/fj7f2z9jrhf2q ... 9.jpg?dl=0
- It is used on big city with lots of start and stop.
- It will have load between 100kg (just me) and 250kg (me + passengers and cargo)
- It will need sometime to accelerate quickly to escape from dangerous situation
-Only need 15-30mph speed. Average probably around 20-23mph.
- It's raining a lot and I do about 600 miles / month. Mid drives are probably out of equation because due to the amount of miles I'd probably have to service the motor/chain/cassette every few weeks and that will drive me crazy
Currently I have a leaf motor 1000w and use about 60v 50A. So 3000W peak.
However, it's not that efficient and struggle a bit uphill and acceleration.
What best configuration for my need?
1. Add a front geared motor. But which one? I consider maybe the q128h at 1100W (55v20A) but I'm concerned on broken clutch
2. Get a bigger rear motor like the mxus 3000
