Re: Identify this secret controller

Easy solution would be for you to wire a relay into the circuit. Use the wire you were trying to use to power your lights to energize the relay, where much heavier power could be switched on and off - easily enough to supply whatever you need to power your lights

Re: Phase wires order

Yup, it matters. The controller and the motor both have to be on the same plan, and normally (in my experience) the phase wire order will be matched by the hall sensor wire plan. I've only done one of these, but got it right on my first try. We know the colors are meaningless, so I figured the motor...

Re: P14 setting on SW-900 display

I think the answer regarding the amperage the sw-900 is capable of might be best answered by the vendor. I think the point is a darn good one, and have to wonder why they are offering this package - unless they are OK with a 20a max output. That said, I think you may be better served with a KT based...

Re: Regen

Speaking from my own experience, the average hub drive using an average controller, will be hard pressed to provide 5% let alone 10. That's NOT to say higher regen rates are not possible. But I think they are highly unlikely using a direct drive hub. Regen is way more about braking power when used a...

Re: P14 setting on SW-900 display

My take, others may have different opinions. From what you say, you may have a 20a bottleneck between your motor and your battery. As far as supplying that controller with a 1500w motor, there's no way whoever put that "kit" together might have known you were going to use a high capacity battery to ...

Re: Best build for 2k or less?

I think the type of drive needs to come first as well. Here it would be direct drive vs. gear driven rear hub. Not a fan of the mid drives.

With the 9 level PAS sensor as the "master", the "throttle" lever (i didn't want the twist) is almost always just for Regen braking, so its more natural than one may think. Excellent point. I don't use that throttle very often either. Mostly just to get the bike moving from a dead stop. I can see w...

Re: Should I fuse my battery?

So if im running 48v with 750 watt motor thats 15.68a, I would be better off getting a 20a circuit breaker over a 15a wouldn't I? If you have a capable controller, you could be stuffing a lot more than 15.68a into a 750w motor. For instance, if you have a 35a controller, at wide open throttle the l...

Re: Should I fuse my battery?

I think a fuse or possibly a circuit breaker, would be part of a good plan. Make it easy to access and no bigger than necessary - based on the size of the wire in use.

Re: 1 kW motor : rear G360, GMAC, 9C RH212, Crystalyte H3540 - or front Grin All Axle ?

It sounds good to me. I almost always apply front and rear brakes together to stop or slow (motorcycle back ground), so that assures a brake signal. From there, that's where I would need to get used to it. I find a thumb throttle more convenient personally. I would have to get used to that modulatin...

Re: Can someone explain this to me?

The controller has no idea of what is upstream from it. Doesn't even care. If the controller is able to flow 100a for instance, and has a 100a load to feed, it's going to do it's level best to try and supply that 100a load with 100a - with predictable results when supplied by a battery capable of ju...

Re: Upgrade controller and display info.

I would suggest there IS some speed being left on the table boy a lot of controllers. It's not a lot, but many/most are designed to restrict a percentage of the battery's available power to limit speed (to keep them legal for starters). Your job, if you want access to this power, is to keep reading ...

Re: Loud clicking noise MAC 12T hub

This noise would be synchronous with wheel speed I believe. Happens under power only, and makes no difference if the wheel is loaded with my (rather substantial) weight on it, or when spun up with the tire off the ground. So that means the noise occurs only when the clutch is engaged. No noise when ...
