Re: My econo-e-bike

This cable is pretty impressive for anyone wanting to consolidate their cable runs. I thought by the Amazon picture that if might be a rubber casing, and a bit concerned that it would easily be cut/nicked and open up. It turns out it's some other type of plastic casing that wasn't even easy to slice...

Re: Searching for a spare/upgrade controller

I think I'm going to get another one of these cheap no name controllers, for modding, and testing. I'm going to order from the same Amazon vendor, and hopefully receive the same unit. https://www.amazon.com/dp/B0B8CRXGTW?psc=1&ref=ppx_yo2ov_dt_b_product_details Given that they all look alike, an...

Re: what multimetre should i choose for present cell mesurement and future home task

A number of decent electronics channels on YouTube have reviewed the auto-off, auto-ranging low-priced Aneng meters. I have a couple. They're small and well within acceptable parameters. It's hard to find the resolution that they have in a low priced unit. I use it less for general stuff because it...

I've measured between each of the balance leads and each cell is bang on 4.0v and are connected correctly to the BMS.

The pack is reading 52v.
Were the cells all charged to 4V before assembling the pack, or charged after assembly?

Re: Recommendations for Torque-Sensing Peddle Assist Kit

Sadly an unrealistic budget. A well built battery will eat most of your budget. But a TSDZ2 is s great choice. What price would I need to go up to for a decent motor kit? Would $1000 be enough. Is the Bafang m500 a good motor? The TSDZ2 deal docw009 linked is the best option for price and torque se...

I agree with AW that a cheap DMM like the one Harbor Freight used to give away is good enough for ebike and home use. That said, I also own a nice Fluke 89 for when I absolutely must have a spot on measurement (which is exceedingly rare). For me the most important features are; Auto off beeps when ...

It is capable as I was able to cruise at that speed with no problem, but as I said once I changed my lcd for a new one it started not going over 30mph.

Most people can't adjust rim brakes let along caliper disc brakes.
An argument could be made that those people should stick with bicycles that have coaster brakes.
Plunger brakes also OK.

Re: Do some BMS's cut battery instantly when its voltage reaches max. discharge??

You could charge manually, which may work, but if the same groups go out of balance within a few charges, they'll always be weak and need to be monitored. You can get a 1S lipo charger from Amazon/ebay pretty cheap. If you're patient you could get the wall wart style, so no power supply needed, but ...

Re: KTLCD3 Problem

Hi, I have built a 1500w 48v 18ah ebike. It has the capability of reaching speeds of 38mph, but on the KT LCD3 whenever I reach 30mph the watts turn from 1500w to 0-200w. So it doesnt go any faster than 30mph and all the watts go down. I know it is restricted somehow as I have reached 38mph on my o...

Re: Truing this Disc rotor is trying my patience

In fact, they are more forgiving than hydraulic discs because the pads retract more away from the rotor when cable tension is reduced/lever released. The disc must be pretty out off true if that's the case. :shock: Although replacing it seems simple, but sometime removing the rear wheel is a bigger...

It's a dual piston caliper. They engage equally regardless of the piston adjustment. I've got it pretty centered this way. I've been using the cheap floating discs: https://www.amazon.com/gp/product/B07DRCVCZH/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 They've held up well. I swapped out m...

Re: More connections bad?

Is this one of the reasons people use xt90 instead of xt60? The broader wires create less resistance? Will that also make the battery last longer, not empty as quickly, or something like that? People use XT90 connectors because they are designed for higher current (~90A) and larger conductors. If y...

Re: More connections bad?

I think you're thinking of resistance. The longer the wire, the more resistance it has. Then, there is resistance caused by connectors. Best plan is to minimize both for the least amount of resistance possible..... Aa ok :) But sometimes life is not that good. And then you need the extension cable....

Okay, I ran the test, and there is resistance with the 3 wires disconnected.
How much resistance. It could indicate that the motor has an internal short. If you hold two of the phase wires together (shorted), do you get the same resistance when spinning the wheel?

Just don't need one E-HP.
