Thanks for the headsup about Hilleater.ca, but their BMS page doesn't show that they actually sell them...

Re: 5-16S Smart Tiny BMS preorder - 30/150/750A rated

The feature I would like the most at the moment is being able to program the BMS via bluetooth. For a display, I use the Ebike Analyzer app, which has a touch display by the fact that it's on my phone :lol: But yes, ideally an app that combines both a display (dash), and Battery Insider for programm...

Re: Adding halls to BLDC motors

I would add the caps on the supply line of the halls, between + and -.
0.1 uF would be OK. Maybe one close to each Hall, if you have a lot of noise, otherwise a single one for the 3 halls will be OK.

glyndwr, I'm not sure you will get an answer from the manufacturer. They seem to have abandonned this forum, they haven't been here since July. There have been many unanswered questions since then. :(

Any chance that you will open one up and take pictures of both sides of the board?
Why don't you just ask for the schematic, while you're at it... :evil:

Re: BIG BLOCK alternative Motor

A 15mm shaft is about 3.3 times stronger than a 10mm shaft.
A18mm shaft is 5.7 times stronger than the 10mm one.

Re: BIG BLOCK alternative Motor

It's not the torque that is going to be a problem, but rather the bending force of a chain pull of many hundreds of pounds, acting about 1 inch from the bearing.
The shaft material will fatigue and eventually will break off right at the bearing.

Re: Adaptto Mini-E/Max-E Owner's Thread

You can also get 8mm bullet connectors. They are larger, shorter, and don't have plastic housings, so you need to insulate them with heat shrink tubing. However, I don't know if they are any good, or even better than the Amass XT150. As for soldering, the best way I found is to pre-tin the connector...

Is Battery Insider V2.5.0.5 the one that is supposed to be BT-compatible, or are we waiting for a newer version?
Do you plan to have a smartphone version of Battery Insider in the near future?

I'm wondering the same. @circuit, could you explain a bit more about the ignition feature? I would expect that once activated via the windows software, the BMS would shut down the load outputs if the selected ignition input is held low, and it would reactivate the load, once the ignition input is p...

The resistor mod consists in a 100 Ohm resistor (1/2-watt) between the throttle +5V and ground.
So the resistor is just placed in parallel with the pot supply?
It won't protect anything then, the only effect is to draw more current from the controller.

If we just had a schematic of the Adaptto, it would be sooooo simple to troubleshoot the different problems that appeared throughout the years. :roll: I haven't followed the thread, so I don't know about the mod. Probably a resistor in series with the wiper of the pot. Or if we want to limit the ran...

Please keep us informed of your investigation.
I was about to order one of these Domino throttles, but if they don't last, there is no point.
I'm curious to see what kind of pot they use, I hope it's not a trim pot!

Re: Kelly kls 7218s stopping hard when throttle is closed and reopened a bit

I've never had an error during the 3 years that I ran with the freewheel.
Still had no errors pop up with the freewheel eliminated, but then had the huge motor braking effect.

Re: Kelly kls 7218s stopping hard when throttle is closed and reopened a bit

Personally, I haven't checked my motor yet, as I would have to make an adapter to match the large output shaft. And as I'm pretty sure that the timing WILL be wrong, I will want to fabricate a new timing assembly (probably optical) that will attach to the rotor and left casing. I already have so man...

Yes madin, I have a 'scope. I will surely check that out, it might be the problem. But in that case, so would be the problem of others with the KLS controllers...? As the BHT is a "cheap" motor, I wouldn't be surprised that the timing is wrong. But it still served well for 3 years with a freewheel. ...

This is probably the same problem I have with my Adaptto; I have been driving a BHT mid-drive with it for almost 3 years now, but recently I removed the freewheel from my rear wheel because of constant breakage of pawls inside it. I then machined a piece that allows me to lock the rear sprocket to t...
