Re: Show Us Your Homemade Battery Housing

Nice and neat! I like the symmetry of your 'penta' spot weld pattern, plus the welds look great. Which spot welder did you use for this?

Love the matched pumpkin colored filament -- very nice touch (or painted?)

Cells connected via spot welding?

Re: My econo-e-bike

My Vectrix VX-1 has a throttle that twists both ways, giving variable, progressive regen when turned backwards while riding, and a very welcome Reverse "gear" when the bike is stopped and it is turned backwards. No need to move your hand to another control for regen. That should be the Go...

Re: My econo-e-bike

EDIT: I think I had an epiphany while riding around today. I turned off pedal assist a couple of weeks ago, and started using cruise control with pedaling instead, which works well and seems as efficient. For the last week, I've just been using throttle, with slide regen set on the controller, and ...

Re: Grin Phase Runner / CA3 and BBSHD

Whenever I've had problems like you're describing, it's *almost always* been a 'bad' (intermittent) electrical connections, often inside a plug or connector assembly. Once it was a broken wire inside an insulated cable bundle that would fail only when it bent in a very specific way. Finding the bad ...

Re: VESC - Motor will not start until a small kick is applied from a full stop despite using hall sensors

Go to vesc-project.com and install the free VESC-TOOL. Look at the documentation for that software and/or some youtube videos and you'll see what the previous poster was referring to. Using that tool, you might want to run the "Detect Motor" sequence and confirm that the VESC controller do...

Thanks for the tips re the all-axle motor. I was convinced I'd have to remove all of the spokes, so removing only half would save significant time. Also, the advice as to the Statorade is encouraging. I'll wait until I end up chasing you through the Alps. I looked at your link to your CA3 housing on...

Re: Around the world on a solar ebike

If you had some kind of wind force sensor, you could have it automatically flatten out during a gust. Not sure if it could react fast enough though. I had the same thought but looking at available wind sensors I didn't see anything that looked small enough and robust enough. I picked up an accelero...

Re: CAv3 Torque PAS + dual throttles 2WD for SB Cruiser

Something I didn't quite get a clear sense of is whether or not the actual throttle input still works as expected. I'll have to test that part. If I remember correctly, the throttle input does NOT retain its functionality, unfortunately. On its intended use with an actual skateboard with no inputs ...

Re: CAv3 Torque PAS + dual throttles 2WD for SB Cruiser

When you refer to using the actual TS input for regen, what do you mean? On the CAv3 using Justin's skateboard firmware, he repurposes the torque input wire on the CA's "PAS" connector ("TS") to do proportional regen braking. When used on an actual skateboard, this reflects the ...

First of all, amberwolf, your one paragraph explanation of what the CAv3 does is probably the best description of this device I've ever encountered. I think it's clear and concise, and not at all just for geeks. Your years of working with it certainly shows your clear understanding of it I'm still d...

How can a CA3 and CA2.4 be set up for a bench test and programing off the ebike? Or do I need to power from my controller?

Change the startup watts to zero, or even a negative number, until you confirm the boost from PAS. Then start bringing up the startup watts to suit your needs.

My point was get rid of the BionX "p.o.s." bms and go either or, BMS'less or aftermarket BMS. Either or, ying or yang. Thanks markz! I think I'll try the BMS'less method on this pack and just carefully monitor the cells. This whole BionX venture has been an experiment anyway, so I might a...

if the cells were new, well-matched, good quality, and used well within "the middle" of their specifications, going bmsless would probably be fine. This BionX 48V pack uses NCR18650PF cells, which apparently have a decent reputation for maintaining balance according to a number of German ...

since you have working systems there, if you have a computer system (or canbus sniffer) that can read the canbus data, you could just connect that system/sniffer to the canbus data wires anywhere in the system, and then capture that data. then you could program that data into an mcu (arduino, etc) ...
