Endless Sphere

I have been reading here for many years. The change? Money got involved. It changed from a hobby to a business. Some have been influenced, some have been bought, some have been scared. Several whose character I did not question, I learned I was wrong. I have seen payment rendered for work done, and ...

You did not buy an e-bike, you threw money away on a lottery ticket. You spent money on a hope and a dream, a marketing pitch which might be sincere, but likely from an inexperienced person with no clue how to run a business. OR, it could be a deliberate scam from a con artist who makes his living o...

48V battery usually has 13 cells in series. 13 X 4.2 v per cell = 54.6. if you have 12 cells in series, 50.4 is fully charged. 48.6 would be 4.05 for 12S, a bit low, but workable. 13S the motor spins faster. Voltage is speed regulation, essentially. Controller should have LVC, low voltage cutoff. Va...

So... You have a 5000w ebike, and you stuck your KEYS into the charging port?...????????? Were you drunk at the time, suffered a recent severe head injury, or had a stroke? For what Possible reason would you do such a thing? Well, first, you are going to need to find somebody who is not an idiot. No...

First, laboratory testing is a wonderful thing and can provide much information. However, very, very few products are exclusively used in laboratories. Another way to look at this - if the weatherman says there is a 5% chance of rain, do you take your umbrella? How about a 5% chance of severe lightn...

First wild guess - somebody fed the BMS some really good LSD? Second wild guess - you live in Canada, and the battery was stored in extreme cold? As repeatedly stated, those extremely low cells constitute a severe risk and should be replaced. That vehicle should not be anywhere within 50 feet of fla...

So, you have blown one controller in less than a month, and the first one lasted an even shorter time. Both happened AFTER the wires were all replaced and re-soldered into the motor. Describe the events surrounding this incident. Powered on when the wires were ripped, perhaps? HOW LONG DID THE CONTR...

Along with a great majority of the user base, I do not possess any device to detect or measure Internal Resistance. I have four, red, LEDs. I know how far I can go, on both medium and high speed settings, for each light, and I know both data points back from when the battery was new. That is all I n...

IMO, Facebook in general is a useless, worthless, total waste of time that I have spent virtually no time at all looking at. It is, to me, a near-perfect example of the garbage produced by much of modern "social media". Unless you really want to know who just farted at taco bell. In terms of ESFB, a...

Sorry I missed the update. Just wanted to note the value of the response, and kudos to the OP for verifying a solution to the problem. So many fail to do this basic step. A collective memory of what went wrong, without the workable solution, has little value other than detailing what did NOT work. W...

The motor, no. Just varies speed, as mentioned, within reason. The controller, however, has programmed LVC limits which often cannot be changed, and also usually physical limitations in the capacitors, ie., Some 36V controllers can do 48V just fine, and Some will pop their caps. Some can do 48 but n...

I am going to disagree with the last quoted paragraph. The difference in storage capacity, available wattage, between 4.2 per cell and 4.0 is not a "surface charge", there is significant wattage which should be available there. A small amount, such as declining from 54.6 to 54, or 53.8 or so, is not...

Keyboard cable would not have enough wires, a VGA cable would. Looking at the amount of work required to parallel as you are suggesting, and considering the issues involved, might it not be more beneficial and not very much additional work to just recell the pack, and have a battery which would last...

Having dealt extensively with proprietary hardware in another industry, that is why I avoid it like the plague and heinous evil foisted upon mankind that it truly is. Now, that is not just a ribbon cable, that is a Mylar ribbon cable. Fairly fragile and delicate, and IMO a royal PITA to deal with. S...

Does your system REQUIRE the Bosch BMS in order to be functional? You have an old, tired, formally 11 ah pack which now has a much reduced capacity. You plan to get a new, 20ah pack, and combine the two. The original pack will likely supply about one-quarter the range of the new pack, which amount w...

"Though frankly, I'd feel better if he had someone with a fair bit of expertise look at what is going on. I feel like he may be missing something here" . Having followed this thread from day one, the above is the understatement of the millenium. Curtis - take the ENTIRE BIKE to the bike shop, have t...

If only I could see it from here, I might be able to help, but, since I can't see it from here, I would have to rely on you to provide something resembling useful information in order to help you out. How did you "fix" the battery? How do you know it had a problem before, and how do you know it does...

Curtis - Hub motors do not come in wheel sizes, they are HUBS. Rims come in wheel sizes, and spokes are made to fit between rim and hub. Ebikeling simply does not offer the service to build a motor into a 27.5" wheel. Take apart existing wheel, get spokes made to order to fit rim to motor, build a n...

So you "came across this controller". Did you trip over it while jogging, find it in the trash, remember you had owned it five years ago, bought it used, bought it new, any info which might be useful here, perhaps indicate it is, was, or should be functional, or appropriate for your motor? Does it h...

What is it you are trying to achieve? More speed, range, hill-climbing? Current plan seems unwise, though doable. That thing about not using full throttle, well, that just never happens. The big DD rear hub is a good choice in many situations, weight and unpowered drag are the drawbacks. Simply maki...

general thoughts - 1. They are heavy and awkward to carry around. 2. The connectors often have a limited cycle life. 3. The connectors often are proprietary, expensive and/or difficult to replace, and lock you into a specific replacement battery. 4. I have yet to see anyone actually using this proce...

I'd like to buy a truck.

Can you tell me which one I should get or do you need some more information about how I am going to use it in order to make such a recommendation, also any budgetary constraints? I have heard Maserati makes a very, very good truck. For less than one million dollars.

Thank you for coming back and verifying the cause of, and solution to, the problem. It is THIS ACTION which makes this informational exchange worthwhile. Without your confirmation, which so very, very many people FAIL to do, no certainty is achieved, no proper course of action is verified. Kudos to ...

Forgot to ask if the delivery address is specifically identified as a place of business. This is very important.

Also very important is to verify tracking info and open a dispute with the shipper. Basically, they will do a lot of the required legal legwork for you.

First, next time you choose a vendor to do business with, do your homework first. There are quite a few people here who will be not at all surprised with your outcome. Did you obtain a specific Return Merchandise Authorization from the vendor? Next, when you ship a valuable item, spend a couple doll...
