I recently got this bike that is just missing a battery. Where was it purchased? Knowing that, the purchaser can be asked what battery it was used with originally, which may help you determine what it can be sued with now. I want to be able to ride for 20-30 miles in a pretty hilly area and am will...

Any time a consumer offers a warning, be it this stuff, toys or bogus offerings, it is a good. What corporation or business looks to offer the consumer better products and service, for their own sake? It doesn't help much to tell people to avoid *everything* of a certain category, etc, unless you h...

Running around the trike,a I meant by using the full length of cable instead of wrapping it and tucking it some where. That still doesn't describe how it's used or routed, whcih is the important part of the answer, in reference to your posted problem. Somethign I would highly recommend for future t...

Is it just a flat ring? Or does it have a specific shape? If it is just a ring, you can make your own out of a sheet of plastic of the correct thickness, as it is just a spacer, based on whatever it shows in the videos and such. If it has a specific shape, you could probably also still make your own...

Presumably this adapter cable came from Grin Tech with the BR. If so, they should have the wiring diagram for the cable available so you can replicate whatever portion of it you wish. Otherwise, you will need to measure the pins on each end of the cable to see which ones are internally shorted, so y...

[quote=amberwolf post_id=1569666 time=1594337066 user_id=138 so do you think a voltage divider in parallel with a t-lever hall throttle will work? Can it damage the BaseRunner? I don't see how it could damage the BR, unless whatever yo'ure doing could exceed the voltage input the throttle connector...

So do you think this is a 1kwh pack... Are these chinese packs still good for the $$$. Is lithium just lithium in the end??? https://endless-sphere.com/forums/viewtopic.php?p=1569938#p1569413 @Bike4life, maybe you should reread your other thread https://endless-sphere.com/forums/viewtopic.php?f=3&t...

The coop is going to be well insulated and sturdy construction. Winter here is pretty mild....Most days with highs in the 30's, but cloudy days can last for weeks in Iowa in the wintertime. Then depending on the actual power requirements, which you have not yet specified, solar is probably not a co...

I assume the cells are ok While this is likely based on the previous posts in the thread, you should still measure between each of the wires from cells to BMS, to ensure they are all about the same voltage, and none of them are too high or too low. The seller of the battery tells me that their or t...

I just noted that the new sensor needs input of 8-12V while the old seems to use 5V... So this might be the main reason for my problems. Yes, if the new sensor's supply voltage is not the same as the old, you'll need something that supplies that for it. You can get a DC-DC cheaply that converts you...

I am running it up with cables from controller and throttle to the CA 3.14. Where the cables are all wrapped in a velcro sleeve just below the CA unit. Then as the topic itself resolved, separate the cable that is from the part that isnt' working as expected from all the other cables. If this ifxes...

If I run the 2X 4 sets together I get over 20v I need to run 2X4 sets but need end voltage to b 13volts If you are putting them in series, then it is not 4 anymore, it is 8, which gives you twice the voltage, at 26.56v (assuming both are exactly equal). You must put them in parallel, which means ho...

Oh man, now I need to spend more money! Back in my medical devices days, the company had a camera that could blow up the view to the point where I could identify a fused transistor in an LSI SMT chip. Your rig looks like something I should be implementing. My hands are still solid, but my eyes are ...

Without quotes it's hard to tell exactly which parts you've replied to now vs previously, so if I reply to something you said before, apologies. I DID THIS NO CHANGE WHAT SO EVER. Then that means the CA is doing everything that is possible to do, before getting to the controller. At this point, if t...

I'm not a power electricity guy (mostly an audio guy) and everything I've read so far puts phase current limits around 1.5x battery current at max (which is risking controller outputs [something I do understand] and motor heating). So expecting a 40A phase current from a 12-15A capable battery supp...

I'm afraid I don't have much useful information, just some speculation based on a few previous "locked display" threads. It's possible the ones you've got have been "locked", and either were made for a specific system or OEM, or simply have a password on them. I don't know how to access the password...

There are a number of types of torque sensor, and several types of output. Some use analog voltage, and that can be in the same range as a throttle or it can be offset by some amount and / or be a narrow voltage range. Some use a digital signal, and that can be in several possible forms and formats....

When it was put in the car, did it have to be disassembled? If so, it is likely to be a problem with any connections that had to be disconnected and reconnected. That could be anything from one not quite plugged back in fully, to a contact that backed out while plugged in, but appears normal when no...

Do any of you ever drill the hub motor flange a tiny wee bit with a drill bit in order to get the spoke head to fit right on the flange hole? If your spokes are too large to fit the hole, you might have to file the hole to the correct shape to fit the entire head correctly. Or use spoke washers, av...

That "9-Pin connector and comes on most every low to mid power capable motor" is good for up to 40A? That would be almost 2,000 watts. 40A on the phase wires is different than 40A at the battery, so you can't measure the power that way. You can have a 9 or 10A battery current and still get 40A phas...

Given I now want to avoid RockShox, what's another reputable brand that won't cost me an arm and a leg? If you just want to get riding, and don't mind single-crown forks, the Suntour XCV(3) or other XCx (XCT, XCM, etc) should work fine, until you can get a much better one. It's not the same kind of...

Given the design flaw, it's not that likely.

"I only see one white wire. Where are the other ones, and what do they go to?" The six solder connections just above and to the right of where the cable exits the axle are all for the sensor wires (assuming that's what they are) to the motor connector. Could be there is a stripe on those white wire...

At least it's not *quite*as hot here yet, but it's already been at least a few to several degrees over predictions, in the actual city itself rather than just at the airports/weather stations. In my riding around the last few days trying to get someone to sign off to let me go back to work (a nightm...

Yup you are right, but then most manufacturers have a maintenance schedule where known problems, such as water collection, can be drained and the motor resealed. Perhaps the OEM bikes do; never looked into those for such things. But none of the typical "chinese kits" or bare motors and such I've ev...
