I always have thought the one universal law we could count on in the Chinese ebike universe is that red would always be Hot

The only "universal law" I have found is that there isn't one.

I just welded a new headtube on the front of the other one. Still worked after a few years of heavy-duty usage. ;) (I had all sorts of problems with mismatched bearing/cup/etc sizes...but nary a problem with the headtube itself) Before finishing-up but after welding on side-bars: https://www.endless...

Does a Cycle Analyst show phase amps or battery amps. You tell me. Battery amps only. To see phase amps, you'd have to have a controller that measures those (some do, some don't), *and* a display for that specific controller that also shows you that info (not sure which, if any, do that realtime).

amberwolf: I just mean a little softer ramp-up/etc. Tomorrow, I think I'll take a look back at the original settings (other than the max limits and RShunt values) and add them back in slowly and test them. I'm sure I can come up with settings that will work for me, and learn some in the process. Th...

the thermal paste shouldnt be dry and crusty, right? if i have blown mosfets in my controller the thermal paste gets all over my hands my thinking was get another one, pop the fan off and put good thermal paste on it There are many kinds of thermal paste. Some of them have no significant solvent in...

From what I've gathered in other threads, I understand that the dc/dc into the CA just gets overworked pulling 72 (really, 84v) down to 10v and can cause it to fail. Pulling up the un/official guide shows that at 84, there's only 10ma and a PAS alone could potentially pull that -- no bueno Basicall...

If you haven't already, you might want to read around the forum for altermotor and/or alternator. There's a number of threads that may have useful info for you.

The way all of the stuff I've seen so far works, is it has an internal pullup resistor (of unknown value) with it's "top" end to one of the internal power rails (probably 5v), and the bottom end to the signal line of the temperature input (and the MCU). Then the sensor in the motor would b...

Well, assuming they didn't use a counterfeit part, that's an IRFP260 https://www.vishay.com/docs/91215/91215.pdf basic specs: VDS (V) 200 RDS(on) (Ω) 0.055 when VGS = 10 V Continuous Drain Current when VGS = 10 V 46A when TC = 25 °C 29A when TC = 100 °C Maximum Power Dissipation TC = 25 °C PD 280 W ...

I have no direct experience, but based on posts here on ES by those that have, it's just another 9C DD hubmotor clone, so is likely to be the same low quality (thus completely typical of ebike motors/etc in general). I would bet that you could use the 9C 280x series in the ebikes.ca simulator to gue...

(BTW, I apologize for the huge graphics in my first posting...I fixed that). You might want a *little* bigger, it's a bit hard to read some of the stuff in the pic in this post. ;) I didn't know that the throttle-only max was bound by the SLim max...on my BBSHD, it can be higher. No problem with th...

Let us know how the Daly BMS works out, and which version you use. I don't know if this will work for Daly (is meant for JBD/XiaoXang) but if you have the time and desire, you might want to try out the OS monitoring software over here: https://endless-sphere.com/forums/viewtopic.php?f=14&t=11062...

I am currently torn on what to do with the situation of not being able to recruit people on this forum even for the work that's paid for. If I didnt' have an exhausting dayjob I'd be able to do more, quicker...but even if I retired right this minute and never went back, it would still take me weeks...

You do realize that took me the better part of a week? Sorry, didn't mean to waste your time on stuff...just that this is one of the best ways to find problem cells in the situation you have. (I think I spent a month or something like that working out the problems with my first non-nickel commercia...

- and I'll be using it intermittenly, that also solves that overheating issue "intermittent" isn't what I would call doing downhill braking. ;) Intermittent would be braking a few seconds here, a few there, with minutes or more in between. Downhill braking of the type I *think* you want t...

I have mounted the motor but I downloaded the program to modify parameters and I see there is only an option for windows 7 or windows XP has anyone has success working with these controllers on a windows 10 computer? I don't know yet. I have a (probably broken) kelly on the way that I can test this...

I bought a CA3 with throttle and the MFSwitch), a Grinfineon 20a controller, and GRIN’s 24p PAS sensor. The first thing I would do is to remove all the power and current limits from the CA. Your controller will do that on it's own, since the current limit of it is the same as that you've set in the...

~ I have run into an issue during the build. I need a durable fat bike tire. Preferably motorcycle tire that will fit my 26 x 4.0 rim (however bike dimensions are apparently weird). So the real-world size is about 22-23" in diameter and the inside width is 3". ~ Does anyone have any recom...

Inside the control unit there is a relay (rated 10 amps at 30 Volts DC) that is connected to this green banana plug. The firmware can cut power to the green terminal when it determines the charge cycle is complete or that the battery has gotten too hot. Per the Riden documentation it is supposed to...

I had a feeling that would be your response. Ok. Sorry; I guess I'm just too old and grumpy and tired of the stuff I deal with locally every day. :( Also, I'm sure you've noticed there are short times when I'm very enthusiastic about things, then stuff happens and have a really hard time working up...

Chalo has been a bicycle mechanic for a long time, and his posts have provided excellent info on brakes, tires, chain, spokes, and other aspects of the common pedal-bike... Perhaps some of those threads can be moved here? That's part of what I started doing...I just havent reached any of those yet....

For what, specifically? A place to upload your stuff? A place to find 3d models? Other??

The voltage drop i measure it by reading the voltmeter (attached picture) that is connected directly to the controller (through the wires that go to the main display( attached picture) that also has the trigger acceleration. OK, so the one on the trigger (throttle?) isn't what the controller itself...

First, by "zero out", do you mean "OL" on the screen? I ask because OL means open-circuit, or very high resistance, which implies a broken wire, while "zero out" and similar things typically means a short circuit, or very low resistance, which would implies a blue wire ...
