    statorade vs statorade w/hubsinks

    I think drilling holes is a really bad idea - You introduce dust and road debris into the motor. On the other hand, if you ingested some water, it will steam out more easily. The best solution is to have the right motor-size for the job. You will also save on your battery wear & tear since a...

    Phaserunner plug breaking

    I am also interested in a solution of how to turn off the plug-braking of the Phase-runner. Not only it can consume insane amounts of energy, it also doesn't obey the battery-current limit.

    Phaserunner V1 issues - Maybe you can help?

    Hi, When the original PR came out, I bought several of those units with the mechanical switch and the molded battery+motor wires. I quickly discovered, that when you apply a regen phase current, the controller randomly will power-cycle itself, causing a short (but potentially very dangerous!)...

    Where to get ORIGINAL Anderson Powerpoles for someone outside America

    Thank you for this! This is what I was looking for :D

    Where to get ORIGINAL Anderson Powerpoles for someone outside America

    I know Mouser, Digi-Key, etc... They are quite expensive to buy from in the small amounts that I need. Our local dealer is also quite expensive, because he can be. This is the problem when you live outside the US... I contacted their authorized dealer in UK which let's you buy and ship products...

    Where to get ORIGINAL Anderson Powerpoles for someone outside America

    Hi, I am running out of andersons soon. I used to buy them at Grin along with my orders, but just to ship an order with those connectors would be extremely expensive. There are some online shops, based in the USA, that sell original andersons too, like https://powerwerx.com/ but they also ask...

    looking for the simplest balancing circuit

    Yes, with a resistor in series of course. But it won't work smoothly as the zener diode start to "open" a bit before the designed voltage, so it will always bleed out some current. Plus, just with resistors, if you have zener diodes across all your cells they won't be exactly equal so they will...

    looking for the simplest balancing circuit

    And speaking of surface voltages, a zener diode could be perfect to bleed out any excess voltage above a certain threshold, but due to their "knee" point behaviour it's not practical. Are there more expensive zener diodes which are have a sharper knee point? 24 of these (for my 24S battery) and...

    looking for the simplest balancing circuit

    I was quoting the word "problem", as a joke. Of course this is an advantage. It makes measuring %SOC by voltage only a harder task within the 30%-90% spectrum, that is all. True. It's more simple to me, as a user. It's very hard not to fully charge A123's unless you want to spend many many...

    looking for the simplest balancing circuit

    From my experience with my 26650's they experienced short-term short circuits, impressive C rate abuses, and after 9 years they lost only 20% of their capacity. My A123 20Ah prismatic cells have had longer short circuit by accident - They let such a high amount of current that the insulation...

    Any lipo checker that is not powered only from first cell?

    And what about this unit? https://www.aliexpress.com/item/4000052302952.html It's supposed to be also a balancer (albeit only at 50mA), but it's enough to assume that it doesn't drain only the first cell, right? And it measures from 0V-5V, according to the seller. (I asked)

    Any lipo checker that is not powered only from first cell?

    I am also looking for something reliable of that kind. I found this product: https://www.aliexpress.com/item/32962134925.html The seller replied to my several questions about it: "Dear friend Thanks for your inquiry! The total voltage of the battery to be tested must not be lower than 4.80V or...

    Real-time cells voltage display instead of BMS

    Looks nice but to pay 170$ just to monitor the cells is too much :) And the whole point is that I find BMS's to be not trustworthy so I would also need a multi-pole switch to disconnect all the cells from the unit when not being used, and switches to bypass the BMS's main leads when not in use.

    looking for the simplest balancing circuit

    I considered those, and they waste almost no power since they just shuttle the energy via capacitors. But due to the accuracy of measurement, and if the voltage on the BMS wires sags due to significant resistance on the connection terminals, then you risk putting the pack away from being...

    looking for the simplest balancing circuit

    Having a midpoint balance is a "problem" with LiFe, since it's their advantage - the %SOC is extremely hard to detect in the midpoint since the voltage is at around 3.3V, and with the accuracy of voltmeters and wire resistances, you may find that even 0.05V difference in midpoint %SOC can result...

    Real-time cells voltage display instead of BMS

    This is a very nice idea and it's better than the current situation (monitoring only the pack voltage), although it's not perfect since after a continuous load of high discharge current the cells take up to few minutes to recover the voltage due to the hysteresis sag. I assume, that some cells...

    Cell voltage via BMS terminal sags while current is flowing

    Hi, I have a 24S A123 battery I have built myself, by using the common screw metal tabs with M5 screws for fastening. I attach a picture of a battery during assembly so you can see what I mean. Since each tab has two screws, then each side of the pack is terminated with two heavy gauge wires...

    Real-time cells voltage display instead of BMS

    Hi, As I manually balance my A123 20Ah pack for 4 years, and as they slowly age, I wanted to have an onboard voltage monitor which shows all 24 cells at the same time. I already have a big handle-bar bag which is secured firmly and I have plenty of surface area on it to mount any voltage grid...

    Grin's MXUS 6T cassette-hub issue

    Hi, I bought from Grin their MXUS 6T some time ago: https://www.ebikes.ca/shop/discontinued/mx3006rc.html It was one of the few at the time that came with the modern cassette-hub. That freewheel had some strange noises in addition to the normal pawl clicking noises right from the start but I...

    Tektro HD-E350 hydraulic e-brake issue

    Hi, I am using Tektro hydraulic disc brake that has a built-in e-brake signal switch. I have it on all my e-bikes. They are identical to Shimano - using the same calipers, priced the same, and work great as kinetic-energy robbers. However, I noticed, recently, that the latch-in/latch-out point...

    PhaseRunner without Plug-Braking

    You say you have rubber disappearing on the sides? Perhaps your spokes aren't tensioned enough and the wheel flex so much during torque-load, that it rubs the frame? (although you would have heard that...) With the software suite you config the phaserunner or monitor it, and it works very well...

    PhaseRunner without Plug-Braking

    The torque ramp times, in the orders you write of, have nothing to do with the tire's flexing. Very short ramp times (like ~1-5ms) can deliver impulse impacts which aren't recommended, and for geared motors this can mean a total disaster.

    PhaseRunner without Plug-Braking

    This is why I made that post, with the hope of finding someone with experience with flashing the firmware of the phase runner, and that has a (more) modern version of Bacdoor than what I have, and can share it. I guess you can understand that if flashing starts and gets stuck which means the...

    PhaseRunner without Plug-Braking

    I can tell you the exact feeling of plug-braking: The controller in that "mode", will prioritise the requested regen braking torque. So if you send the controller the max braking torque (According to your throttle voltage map) and started braking on a flat at 30kph, you will feel the exact same...

    PhaseRunner without Plug-Braking

    Hi, I understand that newer versions of the PR, come without plug-braking. That is - regen intensity diminishes as you approach zero speed, but at no point a positive current will be drawn from the battery in order to provide that negative torque. Plug-braking cannot be disabled via the software...
