Thanks! Spray foam looks like a great solution! The emtb frame actually has a flat down tube where I want to mount the battery, so that's why I'm interested in the flat base. Any tips on sourcing bags? I've been looking at bike saddle bags, and am after long low bag to sit on the down tube. The only...

Thanks for the reply. Re the heat, I think you are right. The way I use the pack and the pack itself being 'over' spec'd, heat really shouldn't be an issue. Thanks for the tips on the mounting too. I'm happy the 18650s are all solid. So it's really the pack to frame mounting I need to sort out. The ...

Thought this would be more generally applicable than ebikes. (I have an ebike battery pack with an integrated BMS on top. Mainly riding offroad) I need a material that will absorb chatter etc. There were some recommendations about eg, yoga mats, but not sure if they would be applicable to slugs on e...

Thanks

I just spent half the morning looking at his Youtube vids

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

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...

(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...

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...

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 e...

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...

snip snip re vesc amps settings... 1. Vesc Amps setting. I don't quite get the relationship between the Motor Amps, Battery amps and Absolute Max on the Motor Config page of BLDC tool. Lets say I have a motor capable of 80A, a battery 100A, and the vesc itself can do 50A - all sustained Amps. What w...

Been testing the drive on my bike and having a lot of fun and I love its simplicity. I guess I am kind of taking it a little outside its intended use, but hey, that's how we have fun, right? I have a couple of things hoping people might be able to give me some tips on. 1. Vesc Amps setting. I don't ...

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...

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

TIA

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...

Wow!

Was there any metal/filings you had to clean out?
Also, what about the large cog? Was it OK?

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...

PAS0 (display) = Assist0 (software) 1=2 2=4 3=6 4=8 5=9 Yes, that's the sort of thing I was after. How did you work out which PAS (display) matched with which Assist (software/controller)? Mmmm, I guess you could program them all to one low value except for one PAS level in software and then run th...

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...

Thanks Guys .....I think I will go with the Shimano M640 Zee Rear Derailleur..It sounds specific to my application,,I assume it would be ok to use with a SRAM 10 speed shifter.???..http://www.chainreactioncycles.com/au/en/shimano-zee-m640-shadow-10-speed-rear-mech/rp-prod82431 This is way off topic...

Kepler

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

Cheers
