Controllers and BT modules are bench tested before shipping. It makes sense to do that because it's costly to deal even with simple problems once a controller left the warehouse. That's as simple as that. This is not to say that this rules out any possible problems down the road but it reduces them....

This question is better asked in this thread: https://endless-sphere.com/forums/viewtopic.php?f=31&t=89847 but I'll answer. The short answer is No. You don't need to maintain any live connection in order for the controller programming values to stick. The long answer is the BT module has its non-vol...

Most phones, even very old ones, can be used as dashboards. Android or iOS, doesn't matter. As it was pointed out here earlier, those phone can be had for next to nothing, so they can be used as permanent dashboards. With that said, a specially made dashboard can be added later if enough people want...

Shooting for 100K eRPM at least. VESC firmware was originally designed to target RC motors, so that should not be a problem.

Dimensions are 60x29mm. The new module is a bit larger because it's designed to take GSM/GPS expansion board that would plug into it (upper and lower rows of connectors). It also has more parts to support more functions. 2019-06-02_11-07-53.jpg What are the dimensions of the new BT module? And is it...

As I've already alluded to in a few other threads, at PowerVeloCity, we are getting ready to release the new updated version of the Smartphone Bluetooth EV dashboard module that builds upon the success of this device: https://endless-sphere.com/forums/viewtopic.php?f=31&t=89847 Here are just some hi...

The first model is using 12 TO-247 mosfets and three shunt architecture (i.e. v6) which provides best possible control over torque and RPMs. However, I am hoping to have a VESC based controller ready for production soon. That one would be rated up to 100K eRPM and should have better support for low ...

The controllers are rated up to 50K eRPM when running in sensored mode. In sensorless, they seem to have no problems running higher eRPMs. In your case, your top eRPMs are 44K, so that's well within the limit. However, I am hoping to have a VESC based controller ready for production soon. That one w...

They are not available in the US. I can send you a few if you are comfortable replacing them. PM me your address. That looks like shorted mosfets on the green phase. Replacing those should bring it back to life. The capacitor isn't shorted so I have no idea what the problem is I haven't been able to...

You can do that as long as you replace ALL four in the group with the same kind. But Toshiba mosfets are not that expensive, so I would just go with the same kind already installed in the controller. I am just curious and lack any kind of knowledge in most of what is being talked about. But i am cur...

Yes, works will all kinds of motors including low inductance.

What motors has this been tested on? Any low inductance high Kv hubbies?

Advice is appreciated and decisions are subject to change. No worries though, it will be great.

This is exactly the point. If you worry about crashing your phone, there are at least two solutions: 1. Don't crash. Frankly, when I crash hard, the phone is my least worry. 2. If you like to crash, get a $25 phone (and a good helmet). Mount it permanently, or carry it in your pocket (another securi...

Adding display is easy. However, that adds to the clutter. There is a possibility that a dedicated display will be added down the road, maybe a wireless one, as an option. But it's not a priority at the moment. No on display. That’s too old school. That's a shame. A deal breaker even. I much prefer ...

Yes, charging will be added a bit later.

I would like to pre-order one. Thanks!

Ps Would it be possible to add charging functionality inside the controller? (like in Adaptto)

On the BT module, we use dual Bluetooth chip that supports older standard 2.0 and newer BLE 4.0. Hence, under phone BT settings, you can see "PowerVeloCity-A" (older, supposed to be backward compatible with Android) and "PowerVeloCity-i" (compatible with all iOS and Android 4.4 and above). The curre...

The controllers has a built-in BT that will allow updates and communication with the phone for dashboard and other things. It may end up soldered to the main PCB or will be a plugin module. It doesn't affect the connections though. In both cases, it will have a separate UART for external use. Would ...

Hey Steve and everyone on this thread. Thank you for being patient and helping. I would have jumped in earlier if I was aware of the discussion. Let's see, just to sum up a few things. The controller was programmed and tested before shipping. It was programmed for 48v nominal. That means that the lo...

Will likely be something simple like XT150 for phases and xt90 for the battery. Not yet decided on signal connectors. Any suggestions?

Any photos of what the connectors will look like?

Field weakening takes away from efficiencies. There is a reason high power vehicles run higher voltages. This is not to say 100v or even 60v mosfets can’t be put in. Not sure what kind of hassling with shunts you have in mind. There are no shunts involved here. Only high precision current sensors. I...
