Re: How to troubleshoot a pedal sensor?

After checking that the wires are connected in the correct order, verify that custom parameter 'C1' is set correctly, depending on the model of PAS sensor you have.

Re: PV NextGen Controller FOC compact 150v 22kw Max - $499

You'll have to excuse my question if it's already been answered elsewhere. Will this controller need to have its EPROM reflashed every time in order to change any settings? As I understand, this is the way existing Powervelocity controllers work, rather than having a 'live' connection between the ap...

Re: Breakout PCB for Eltek Flatpack2 [EU]

Just to add that I've been able to successfully program the silver Flatpack2 HE 3kW power supplies. As far as I am aware, any of the 'HE' (high efficiency) units can be reprogrammed.

Re: Cycle Analyst V3 preview and first beta release

Hi All I'm setting up my new ebike w/ a CA. I got everything working great using the Aux input (a potentiometer) to control the power limit during PAS. I am now trying to set up a preset to use the pot as a speed limiter (have the CA keep constant spped by varying power). From reading the docs on G...

That's a shame. A deal breaker even. I much prefer dedicated purpose built hardware as a UI than messing around with smartphones and apps and I'm pretty sure I'm not the only one.

Is there any chance you'd ever reconsider this decision in the future?

Re: Are there any full suspension bikes that can hold a large 72v 25ah triangle battery?

The Giant Anthem features about as large a triangle as you're likely to find on a modern FS frame, but a 1800Wh battery is probably too large. Could be wrong though.

I believe the RShunt value cannot be "calculated"
Of course it can. All you need is the published voltage drop at a given current:

50mV / 300A = 0.1666 mOhm

I just purchased a new shunt for my next project and found that the RShunt value supplied is actually the same as the potted units supplied by Tangent (GrinTech) even though the current lev...

Re: Where to buy cheap Li-pol batteries instead of Multistar?

Hi everyone. I am new here, but I read a lot of topics here before. I have DIY e bike. I have been used Turnigy Li-po batteries, but they start to be weak. I am thinking about change. I would like to use 26650 5000 mAh instead Li-po. But, no Li-ion is so hard as lipo, as we know, and cut off voltag...

Greater power density. Have you seen the size of the Flatpack '2' (2000/3000W) & 'S' (1000/1800W) compared against each other?:

Re: Cycle Analyst V3 preview and first beta release

I am still confused why the power is greater (measured only by how damn quickly the thing accelerates) with the old incorrect shunt value and back to somewhat slower (old grin shunt levels) with the correct calculated value....perhaps my new shunt is not as stated (50mv and 300a)?

Re: higher or lower kv

a) use a high kv motor (12kV) and a high battery voltage (96V) to get the same top speed. You dont need a controller with high phase current (only 100 amps), but one that can work with high pack voltage (rated for 110V max) b) use a low kv motor (6 kV) and a normal battery voltage (48V for example)...

Re: higher or lower kv

Im way late to the kv discussion but Every time i look at high vs low kv in the simulator it ends up in a situation where the low kv makes more power but overheats faster, and the high kv makes less power but overheats slower That's why im not sure theres a one size fits all solution Assuming both ...

If he had, I imagine the asking price would be higher. Nothing stopping you from swapping out some components and selling what you don't want though.
