4 cells in parallel (aka a string or group) is the capacity 4 x 3000 is 12000mah/12ah. The max capacity one can get with 4 x 18650 cells is 13600/14000mah. Each parallel string of cells in series connection make up the pack voltage required. Each parallel string can only be the voltage of the...

With the 4 pin leds one can get away using any generic 4 pin type usually, but with 5 pin there are more comms between controller and display to confirm compatibility.

Unfortunately many brands use the same generic looking display, problem is each manufacturer has different commands/protocols when it comes to the intelligent 5 wires models. Kingmeter typically are used with lishui controllers as you have on the Pendleton. 8fun are the marketing name of Bafang...

I suspect the 890 led was a KT model possibly or an 8fun one.

I over looked reading the Brainpower bit . If it has the self learn process, it should be automatic if done correctly.

The only reason to have more power is if you wish to go at moped speeds all the time, then you inherently add far more danger not only to your self but also bike failure.

A tri keyed spanner, it would sit in the three indents visible on the surface of the first pic.

Because of the moped class which uses a twist & go throttle, before the law change the UK hadn't harmonised with the EU regs in law. They were only adopted officially and legally on 01.01.2016, before then we had a 12.5mph and 200w limit. To allow twist & go, a different category as has been...

Carefully look at the cable where it enters the hub, wires can easily be damaged at this point or a Hall sensor has failed. Halls are very easy to check with a basic meter, esp if you have block connectors like SM ones.

Only by trial and error, there are 36 wire combo's in total to try. You may get lucky by swapping over just a pair of the phases. Phase hall combo diagram in #4 below Ezee Hub Motor Problem | Pedelecs - Electric Bike Community

If the lump/bump once every revolution is felt when riding, then look at the shape of the tyre circumference as you rotate the wheel. Sometimes a pronounced unevenness can be seen in one spot or one can see the tyre wall at the rim edge isn't uniform in a particular spot. If tubes are fitted it...

Ebike throttles can be used if one gets the bike msva tested or if one has throttle setting of pedal first to use it, it is no big deal to turns the cranks 1/4 - 1 turn to activate it if needed. The main reason is to reduce the categorising of an e push bike in to a moped/scooter class. It's...

I only go to 40f & 50r psi on road, if off road front is 35.

If you have centre knobbles on your tyre it will be bald within about 300 - 400 miles, I changed my WTB riddler for a Spec pro 2bliss and wear is negligable. Still loving my Revos mk1 I bought as a kick starter option. Power delivery is excellent and the ride feel is totally different to my...

Nothing wrong with it, as you have found out now power it is a pig to turn. Reason being is that it is a Direct Drive heavy hub with no gear reduction like a much better geared hub.

Use a standard voltage charger then, set the BT BMS to 90%/ 4.1v per cell balance. Once the 90% balance charge is reached the BMS will switch off the current and the chargers light will go from Red to Green as normal.

Because they aren't and we will be left to pick up the pieces when you have buggered off the scene having posted misinformation. You can't mix different brand connectors and expect them to work.

It's not a charger you really need for 90%, ideally you need a BT or Uart BMS which then can have the balance correctly set to 90%. Then you know for sure the cells will be looked after correctly and can check cell balance when ever you like.

Please stop calling these connectors mutual style otherwise you will cause issues for other diyers. Julet and Higo are compatible fit wise but that is it, the wire sequence is different between the brands so not compatible in simply swapping out components. One has to make sure if using Higo...
