A link to the battery seller/site. The charge is an average of 4.05v per cell so yes it is shy of a full charge. Then again are the BMS specs intentional to balance at a max 4.05v ? I for one and a lot of other users would be happy if 4.05v was a max charge as cycle life would be great.

S09P 500Watts Torque Simulation Square Wave Controller (bmsbattery.com) Any display preixed by S is compatible with the controller. Meter/Display (bmsbattery.com) This controller and the displays use current control so one has more control over the power for a better relaxed ride, they are...

BMS battery sell sensorless controllers one can choose from KT, Lishui or there own KU brands. Controller (bmsbattery.com)

One doesn't have to have a sensored hub, there are some or were unsensored controllers available or one can simply not connect the sensor wires and hopethe controller works ok without error messages. Ideally one wants a display to go with the controller, a pedal PAS sensor,a speed sensor and a...

Generic 21700 celled batteries we will see are likely to be mediocre cells or ones the big EV boys have no use for. 19ah 21700 hailong's are already available from about £360 with Tesla Panny cells, but one expects these are either non graded cells not fit for Tesla or reclaimed cells...

One could nearly lose the 3kg weight entirely as 21700 cells are about 68/70g each compared to 48g or so of 18650 cells. 10s 5p/17.5ah of 18650 cells is approx. 2.4kg , 10s 4p/ 20ah of 21700 is approx. 2.72kg. So marginal weight gain per battery but yes the loss of a almost a complete weighty...

Sub 5000mah then we will be seeing some very good high discharge cells allowing for smaller/lighter batteries in the 21700 format, above 5000mah one expects most will be mediocre cells that will at least need 3 if not 4 or 5 cells still in parallel. What folks have to be careful about is how...

Any capacity with 21700 is dependent on the case size to accept the larger cell format, but current case sizes one would expect 3 0r 4 cell in parallel max. For capacity all one needs to do is X the cells in parallel by the cell mah rating. So theoretically if one could get 4p of cells in a...

I forgot one of the current best rated 21700 cells is the moli p42a/35a cell, it is soon to usurped by the new moli p45b/50a rated cell and an increase near 9% usable mah as long term tested by mooch on ecigs forum. One expects it not to be a cheap cell though.

I have noticed some news on two cells very recenlty. BAK have a new cell at 5300mah, the 21700CD. A 1c charge rate and a 1.5c discharge rate which tbh is ok for a mediocre current rating. Not much use for a 2p battery config. The other cell is very much more interesting an LG M58T currently...

P1 shouldn't have much to do with PAS but a widely incorrect value can affect motor running and speed. 8 or 10 will work, I don't know why but some 12 poles just don't work correctly with KT so after one failure I have never bothered again. The common julet 10 pole PAS is the BZ10c but this...

Agree. I do have one but only use it for phone calls via whatsup as they are free to another whatsup user.

It is simply down to the Hall sensor used in the PAS sensor some work both ways, which is a bit annoying if one pushes the bike backwards or back pedals. I had one like that and simply set C8/0 so that the PAS level defaulted to 0 when screen is turned on otherwise I always made sure PAS level...

Yes, spoke holes are offset so as noticed every other one. One laces as you have mentioned, the spokes on the drive side to the offset hole on the same side on the rim. On #40 in the thread below I listed two wheel lacing tutorials to follow both are very good and show you correctly how to do...

The four wires on the old system means it was a torque sensing BB system, one can't use the TS BB system as the controlller input/outputs are incompatible. If the TS BB cranks work ok with the wiring disconnected then one may be able to fit the Cadence sensor and magnet disc but we will need...

Try all the other C1 settingd to see if it makes any difference. I did have a 12 pole disc and my kt refused to work with it, a 10 pole one worked perfect with 01 setting.

P2 is simple, it is the number of motor or spoke pick up magnets for sensing usually 1 or for some hubs 6. P1 is a bit more trickier to understand, the figure to input will give a odo readout with the display set to a certain speed. The P1 value is motor winding magnets X the hub internal gear...

I have a couple of different £20 type camera's, one a gopro clone and the other an all plastic bullet type both capture the car plates well for reading. The easiest camera is the bullet model a simple same button touch of on or off. I did have two of the bullet models mounted front and rear, I...

Could be wrong polarity of the magnets, simply turn th cranks a/c/w to see if the PAS activates. Is the wiring sequence correct at the connection ?

Some of the gopro clones can be quite good for daylight footage, cyling uk forum someone recommended the goodmans one about £20 from B&M store. My gripe with any of them is the realy poor battery life of barely an hour or 1h 20mins .
