Re: Sag from cells or from heat/resistance?

My thought is sag is about the cells as a rule. Wire and strip size aren't changing to cause the sag in available voltage. It's way more about the cell's ability to produce a constant rate. Some are clearly better at this than others.

Re: P14 Current Limit Setting

Just a thought. Maybe consider something WAY more than you need next time, so you can USE it at about 50%, knowing there's 50% in reserve when/if you need it?

Re: Question on installaion of Bafang g062.1000.DC 1000W

Using spacers or whatever, at risk would be disk brake alignment (rotor centering in caliper), and your chain line/derailleur alignment.

If you have a UART based Ultra, the correct software, and the programming cable, it SHOULD work. If not, you are likely doing something wrong.

Re: Are these wheels not laced properly?

Thanks for all the replies, This is a rear QS205 which is intended to go on a Stealth Enduro Style EBike with big power, like 8000W. There is going to be a lot of torque on these wheels for sure. Fingers are crossed that these will hold up but now I've verified my doubts. 8000w in mind, or even hal...

Re: P14 Current Limit Setting

This is way out of my league, but I'm wondering just how comfortable you are with 2 things. The max amperage ratings for the battery/controller/motor you're using (knowing full well manf's have been known to stretch the truth just a bit), and the size of the wire you're using to carry this amount of...

Re: Taking steep hills with a hub motor

Pulling that kind of power regularly, for more than a few seconds, is an invitation to a burn down/long walk home. There is little doubt you are going to start burning parts eventually. That motor is only able to produce the power you're talking about for a minute or so and will then need a cool dow...

Re: Rear Bafang hub motor speed hack?

With a hub driven bike, it's not about the display you use, it's the controller that determines the speed limit - if there is one. If I'm reading this right/understanding, your display setting is not affecting the controller's setting. If that's the case, there's a very good chance the controller is...

Re: What can a Grin controller + cycle analyst do that KT controllers + KT display can't do?

It is on the white wire that in theory temperature gets "multiplexed", if the motor has an internal temperature sensor tied in with the speed hall sensor. I believe that my friend, is wishful thinking. If you show me a KT display successfully displaying a motor temp. THEN I'll believe you.

Re: What can a Grin controller + cycle analyst do that KT controllers + KT display can't do?

With the KT method of doing things (serialized data wires), there would be no extra/dedicated wire necessary. It is a hardware issue, as there is no place to connect the data wire coming from the temp sensor. That said, would love to be shown that's not the case. I've installed a bunch of these and ...
