Re: Australia - resources for e-bikes, kits and parts

Sorry for the necropost, but thought it better than making a new thread.

Does anyone know someone in Sydney who can put together a battery pack? I have batteries BMS etc coming, but need somebody with the equipment/expertise to assemble it.

TIA

Re: Bafang MAX drive (250W) readout

I tried searching, but couldn't find the answer... Both the Max G330.250 and the G330.350 mention rated voltage at 36/43/48. Does that mean that you can use anything between 10S and 13S battery? Or are they special builds for each of those voltages? Anyone running one of those 36V motors with a diff...

Re: I bought a Bafang Ultra full suspension fat bike from Alibaba.com

(any suggestions for a 8 speed with a climbing gear?) Last I looked the best you can do with a Shimano was HG31 or HG41 11-34T. Haven't looked at SRAM, but they didn't seem to go to 34. But the Sunrace M680 is an 11-40T cassette. You can find it on ebay. Alternatively, you can always punch out pins...

Battery options...

Hey there. Thought I would toss this in for other's consideration I had been inspired by some of the earlier builds that used standard Li-Ion power tool batteries, especially mhaskell's powered by 18650s. Over the hobby batteries, I liked the: *Can take the knocks - made for heavy duty tradesman *Ba...

Re: Kepler Friction drive comes of age.

Something has been bugging me for a while, and I just wanted to mention it. I think we should keep in mind that Kepler is providing the drive bracket and it's really our decision on the infinite battery, motor & esc combinations. Kepler has gone above and beyond the call of duty in sharing his exper...

Re: Kepler Friction drive comes of age.

Thanks for the replies. a) Does it make any difference to the amps settings for motor/battery if I'm using a throttle set to current mode vs duty cycle in the ADC app config? b) Also should the rated max amps of the VESC itself fit into this? Eg, if the VESC is only rated at 25A continuous, then I a...

Re: Couple of questions...

Lets say I have a motor capable of 80A, a battery 100A, and the vesc itself can do 50A - all sustained Amps. What w...

Hi John, <snip> Am still amazed at the hookup on my MTB tires. Doesn't feel like slipping at all. Ill be hitting the trails this weekend to see how it behaves on the dirt. I'm guessing the bumps etc will make it slip and also fine dirt. What tyre are you using? I'm doing a MTB setup too and went tr...

Re: Upload Your Circuit Schematics & Requests Here...

OK, so you're saying to protect the throttle:

*+5v controller to +5v throttle
*-ve throttle to -ve controller
*signal throttle to 1k resistor, 1k resistor to +5V brake, -ve brake to signal controller, and leave brake signal unconnected

Re: Upload Your Circuit Schematics & Requests Here...

Thanks for your post. I'm just not familiar with the terminology, so I'm instantly struggling when you mentioned common and shorted etc. Supplying no power, with the brake 'off' (magnet near switch) I get no ohm readings from any of the 3 wires. With the brake on (magnet away from switch) i get a re...

*I have a controller that has only one input analog signal that is available with 3 wires, +5V,-ve, signal. *My throttle has 3 wires (+5V, -ve, signal) that outputs up to ~3.5V *I also have a reed switch brake sensor with 3 wires (+5V, -ve, signal) that reads 0v when the brake is off, and +ve voltag...

I ran into the same problem as innkeeper described above. My frame mount battery from em3ev was manufactured around the same time (ordered mid Aug, arrived early Sep). Paul from em3ev will be shipping out a replacement BMS for me also. In case anyone else runs into this, I'll just add on that Paul s...

Re: Programming the Bafang Middrive BBS01+BBS02

Quick question: If I set up 9 different PAS levels, and then later select, say, 3 PAS levels from the C961 settings, does it just use the 1st three PAS levels? If not, what which PAS levels does it use? I guess I'm asking how does the C961 settings of number of PAS levels interact with the PAS level...

Was there any particular reason/workaround why you limited the current to 18A from the 25A it was originally?

Just to let everyone know, all is good.
Finn replied not long after I posted my message, and the spider has arrived a couple of days later.

Looks like a quality part, and I'm looking forward to fitting it when I do my install!
