On bikes, I have to comply with the 1/1/2016 law, twist and go throttle is not allowed. You have to pedal or long press the - button to start and then pedal for a few seconds to activate the throttle. On kits, that law does not apply, you have twist and go throttle. That means the throttle is...

they use unmarked reject cells and labelled them as their own, consequence of that: the cells are unmatched, the pack falls out of balance and next time, when they charge to full, the pack starts a fire.

I think the safest move may be a wide adoption of intelligent 41V charger with complete history stored in the cloud so an AI can help with safety but we need to quantify the cost/benefit. Bosch may have already done that.

the fault may be in the cable between your controller and the LCD.

ruptures are accumulative.

motors have constants, Kv, Kt, Km are the most used for selecting the best motor for a job. Nobody lists them in a table for you to use but wiki motor constants, the article explains better than me.

The fundamental of PAS programming is still the same, the controller keeps you pedalling regardless of 'speed control' or current control. Basically, if you put zero effort into moving the pedals, the current will be reduced to near zero and the bike will slow down to a crawl. The key...

BTW, I decided to stick with Tongsheng TSDZ2B, 48V 250W. I feel that the B revision is good enough on a tried and tested kit while the DM-02 from toseven still has a way to go.

The charging is finished when the current is < 100mA at 42V. you would need to add an ESP32 or similar to control the charger via bluetooth or add a TFT touchscreen to the charger.

I did say 'seems to have lost', it's a typical question when someone noticed that the bars on the LCD battery meter went down more quickly than before. I reply that the first thing to do is to leave the battery on charge for several hours to make sure that the battery is fully charged and...

Small imbalances are inconsequential. You only need to leave it on longer (6/12/24 hours) if the battery seems to have lost some capacity, something like 20%

it's not a limitation by Lishui. They supply the code to suit OEMs. Their default code is practical for most users. It's not an on/off switch based on speed, it's a step change in effort based on the selected assist level. The main difference in the Lishui's 'speed control' - for lack of a...

in the thread throttle for the Carrera, my code implements just that, the throttle takes priority as long as you pedal and cuts the power as soon as you stop pedalling. Lishui and others keep the throttle going until you blip the brakes.

the throttle + pedalling = legal + precise control of the amount of assistance, from snail's pace (negotiating gates for example) to 15.5mph while pedalling as little or as much as you like. A combination often overlooked because difficult to explain to the police and most people don't need the...

16.2mm is OK, the sensor won't crack, just jiggle the sensor case a bit to fit it better. Post a picture of the splines on the bb cup if you want me to check.

I noticed that point in your experiment but you have not yet repeated the same experiment with Sturmey 's diode idea.

I think there is strong interest in charging at 41v in order to prolong life of the battery and reduce fire risk during charging. However, the cost needs to be quantified, how much loss in capacity? I can get 41v chargers made.

Can you make a discharge curve like saneagle's in the other thread?

the charger has CC-CV function

You have to deduct National insurance and income tax, management cost repairs and insurance etc there is little left if you have to pay the mortgage.
