No worries, I am just sensitive to technical nonsenses. ;) You right with the BMS functionalities. Basically it monitor cell voltage and currents and shutting off output when out of range. Usually BMSes are set to 2.6 to 2.8V per cell as undervoltage. (Dengfu battery is tripping at cca 2.8V per...

Please do not make up things. There is nothing like "controller sends a request to the battery to reduce output power". Battery can not regulate output power, controller is regulating power to the windings. We have enough of untrue on this world, so please stop this, especially at technical...

Sparking is normal, it is inrush current into controller capacitors. You can use black antispark XT60 if you are not confident with sparks. ;)

Bafangs are taking one cell up. Just you will get then wrong battery SOC % reading. This can be vcompensated by K1 BBR, and also it can some other tricks. You can use 52V battery and 48V firmware.

I got it now :sleep:... you went till battery died. Indeed here is something not OK, it is too much difference. Quick calc from your numbers and for 250W max: 10.84 Wh / km - M560 7.38 Wh / km - M820 +46% consumption I have good measurement against M620 Innotrance (VESC controller, so lets...

Hello Hmmm, thats quite a big difference 39 vs 42V left. Efficiency of M820, or this motor is running in higher rpms, where more loss. I can check in charts what is the difference in capacity taken, is it 5Ah battery? But that looks to me too low for 30km and 720m vertical. Also dont getting...

Hello. When not connected CAN battery, you will have Battery Info Screen greyed out on your display. You can check also BBR device if you thinking about tuning and to use 48V battery with 43V firmware. ;) www.k1ebikes.com/bbr

Had same issue, when I saw it on a video from action cam. ;)) Also been thinking whether to put on YT. As it could do a bad name for the motor. Actually it is the best motor from Bafang. For me. Have also M620 2kW, but it is 28.5 kg and man, you can feel it. Power level is one level up, but is...

That is right and you wont buy M600 soon. Bafang is just selling them off now for a good price. M560 is more loud then M600, but not that bad. No more than HD motor. But for the extra power it is worth. From videos it sounds quite scary, but it is that action cam, close to motor. On your own...

It is Go+ app over some Bafang display with BT. For example DPC245 or DPC080. Just you still wont set Assistance level % over GO+. Check K1 Flash, simple and works without passwords. www.k1ebikes.com

It has both sensors. It is strange you dont feel the difference in assistance. Is much much better comparing to M500 or M600. Check for the settings of controller if all good.

Hello Hold down and power button on error screen.

Does somebody know what voltage is Panasonic GX using for lights? Can not google it.

With this simple Speedbox not possible to switch. Only way is to use light connector to switch speed limit. Or I have also the one which is reacting to a magnet and is hidden under plastic cover.

So accurate energy consumption from BMS. Try to set similar max power on M560 to M820. Try same trail and get similar time. You can post then. We can calculate Wh per km.

How you found out? Should not be such high difference. Could depends on rpms it is running (efficiency). Did you run at optimal caddence? Lot of people is riding with low caddence, then part of energy going to heat. I do not see any major difference in consumption of M560. I am comparing with...

Great. Will you also turn back one 13mm socket for me and shipp? Will pay. The nut is 13mm, no? Other solution is just to cut a little of carbon around nut with a dremmel.

Try this tool. But much better to turn down OD and tighten nut and not the bolt.

Could be. Also have old motor, which has different boot code. Usa version of motor. So just edited bootcode to take firmware v1.5 Now seems to me there is no different bootcodes with new M560.

With laser engraved label it will be old M560. Now they putting only sticker. Also 750W version is reading as 500W hardware.
