KT make both sinewave and squarewave the difference is in the description and image of the connectors, Sq wave don't have the 5 or 6 hall wires.

Nope, only the first three are DC volts 600, 200 & 20v.

The compact controllers for integration with batteries don't use the traditional U shaped wire ones instead they use solid state ones (small flat black shunts).

That's where you went wrong you don't kneel on them, they are for your bum.

These and many others on AliEx are all false with claims that just done add up, come on £40 certainly just doesn't add up. At the very most it can only be 10.5ah as the largest capacity 18650 available is 3.5ah. Similar ones have been posted on here before and on ES and only a fool would be...

Samsung makes lots of cells depends which cell designation ? Some are better then others.

I took it as his road speed :rolleyes: , hadn't given it a thought that it might be just a no load throttle speed.

Now and then you will come a cross the odd TIT, but they are always there in all walks of life.

In the first reply #2 I asked you to check the wire continuity over 50 posts a go and we still are no further forward of knowing. We start with the known basics to try and disregard them. To tell a lie we haven't asked about the battery, at the time it worked so assume it is giving out good...

47mph what model did you fit ? BBSHD ?

It's not less voltage you need it's the current rating. You have a 48v battery so the dual voltage controller is capable for the battery voltage. Depending on the cells used in the battery, the 1500w controllers top current may have already caused damage to the cells.

The harmonisation of pedelec standards it works across the world esp in the EU where UK users are more likely to take their bikes, even Aus/NZ have the same laws and they are quite hot on lawlessness. The only place really in the evolved world where speed and power differs is the USA and over...

Yep that looks steep.

I have no experience of the TSDZ so others with them may be able to help. There is a massive thread on ES(Endless sphere) if you have several days to read it. We are only assuming what the OP has said as we have not seen/heard his motor under power.

As vfr has mentioned a logical sequence of testing components is required before trying to jump two steps ahead, the jumping ahead steps prove little until the first steps are carried out. In the case of a motor spinning out of the D/O's first step is to confirm all motor wires show continuation...

A great first post Dave and welcome to the forum, nice to have a new sensible head joining giving an unbiased view.

It may well be that the small Voilamart geared hubs are better value then we give them credit for ? Try a steeper hill to find it's limit or until the nylon gears strip. The difference is not about speed but how both deliver the torque as the inclines get steeper, as they become steeper the...

The controller draws more current then the 30a continuous BMS can deliver so it will cut power, though the BMS should be able to deliver above 30a for very short periods (10 - 30secs) if the cells can deliver. What is the battery cell used, not just the cell maker but the cell designation. In...

Buy a kit that allows you to peddle well beyond the motor assistance. My 14.5/15kg Pinnacle Arkose inc 2.5kg friction drive has a legal tamperproof 25kmh cut off, no display what so ever and is a simple Reention Bottle battery with controller base, drive unit and a rear sprocket led pedal sensor...

The two bikes offer an unfair comparison, one has to use the same motor/controller/battery and bike to make an ideal comparison. The Voilamart and Bafang most likely have differing motor winding speeds. The fat bike will be slower as it is a heavier bike to ride and has more rolling resistance...
