    Read And Weep

    No. Without evidence, we do not. You would hope police action also hinges on this basic requirement.

    Prices of the electricity we use to charge

    Gary Stevenson, also known as Gary the Economist, is a British economist and former interest rate trader who gained recognition for predicting the 2008 financial crisis. He is known for his analysis of wealth inequality and advocates for policies to address economic disparities. If you haven't...

    "Sodium-ion Battery packs for electric bikes"

    At present, sodium-ion cells are almost 50% as energy and power dense as lithium-ion cells, meaning that a pack of equivalent performance will be around 200% larger/heavier.

    ALWAYS REPORT SCUM DRIVERS

    That's a fair enough position and also the socially accepted 'truth'. Ask yourself however, do you want to be 'right', or do you want to be alive? A little pragmatism goes a long way.

    Help! How to set up KT T06P LCD4 kit + 250w sensorless motor

    I wasn't suggesting that I've never tried altering C2, just that I've never quantitively measured it's effect, nor seen a detailed explanation from Suzhou Kunteng Electronics.

    Help! How to set up KT T06P LCD4 kit + 250w sensorless motor

    I have always assumed that C2 alters the phase timing/order, but have never actually been able to confirm this. Phase degrees could be part of the calculation.

    Help! How to set up KT T06P LCD4 kit + 250w sensorless motor

    Older KT displays only have two options for custom parameter C2, newer displays have eight.

    Would fast charging make much difference?

    It could be argued that 'solar charging' is the paradigm and 'night cycling' is the solution.

    How much battery sag is too much for a 3 year old battery?

    No hard & fast rules here really. A battery is 'past it' when it no longer delivers the performance required.

    Anyone ever tried to implement regenerative braking?

    Why on earth would you want to pedal harder in order to increase energy capture into the battery? Why not just use the pedals to power the bike directly, without any of the conversion losses, complexity and engineering challenges involved with regenerative braking? Don't get me wrong, I'm a big...

    Would fast charging make much difference?

    That is correct; they do not provide any DC rectification or voltage/current regulation. They only convert a Type-2 charging point to a UK plug socket (BS1363).

    Anyone ever tried to implement regenerative braking?

    While I'm here, my thoughts on regen: Regenerative braking is not worth basing a whole build around. However, if you feel that a direct drive motor is the the right type of motor for you due to its reliability and high power capability, regeneration is a nice extra that is definitely worth...

    Anyone ever tried to implement regenerative braking?

    It's what YOU are discussing, but not what was initially raised (using a turbine to recapture energy generated from a moving bike powered by a traction motor or pedal power). Apologies if I've misunderstood.

    Would fast charging make much difference?

    It doesn't have to. It just defines the MAXIMUM charge rate of the charging point. The reduction in charging current that you describe is a natural consequence of the CC-CV (constant current, constant voltage) charge profile used when charging lithium based battery chemistries.

    Anyone ever tried to implement regenerative braking?

    Okay, but that's not what's being discussed here, is it?

    Would fast charging make much difference?

    Don't forget, the charge rate is practically limited by the current limit of your own ebike charger. AFAIU, the value of the resistor dictates the agreed maximum charge rate of the type 2 charging point, but I'm not 100% about this. Anyone else have any input?

    Anyone ever tried to implement regenerative braking?

    Oh Christ! I can't tell who's being serious and who's not now. My fault for getting sucked into such ridiculous conversations....

    Anyone ever tried to implement regenerative braking?

    It's not free power! The energy to power the generator has to come from somewhere. Rather than dealing with all the efficiency losses created through energy capture and conversion, why not just use the input energy to power the bicycle directly?

    Would fast charging make much difference?

    If you scroll down to the feedback on the product listing, you can see a number of individuals using it to successfully charge their ebikes. I think the 'handshake' you mention is just a constant voltage present on the 'CP' pin, dictated by a specific value resistor contained within the adapter...
