A square taper is a std for BB's where just a BB or a mid drive, I will be using a pair of shimano cranks as the Q factor is less.

Most chargers have a screw x4 at the base feet location, the pots are easy to ID or if unsure show a pic. Some chargers use a solid state pot so not adjustable. The 4096 modules for each cell group will be a faff if one was to go down that route as each cell group would need it's own jst...

1. Yes if the BMS doesn't shut down. If the motor works then yes one can use the BMS as 9s, though one will have to monitor the discharge voltage. Depending on the BMS lvc you may not need to monitor voltage (but it is better to do so), If the display doesn't have a voltage read out then wire...

As per the title. Any one using a UART BMS in their battery build ?

The Gospade is a clone to a degree of the BBS, the engineers are ex bafang employees. However the motor is light so may be a bit flaky like the tsdz2, they aren't widely available in the west so reliability unknown. Woosh once thought about stocking them but never cam to anything as they...

Depends on the riding but I have used a both a bbs01 and hub for off road riding. The hub I find more reliable then a kit mid drive. Not yet had a hub fail me or a controller to the point where I can't continue, I have had two GSM failed on long rides and two BBS controllers.

The halls will be fried so the need replacing, one need to open the motor and pull the motor apart. Whilst at it the motor cable needs replacing to be honest.

Awaiting items from China /AliExp, I have the ST programmer stick and spare motor spd cable so will make this up next week and get on with downloading the various programmes needed to the laptop to enable OSF of the motor and std vlcd 5.

One can post it on Woosh web site used page for free, contact Hatti to do so. Also on this website under the classified section.

CJ if OSFing or modifying the drive then any relevant warranty is out of the window so in this case no need to worry about warranty. The tsdz is a bit sloppy on build quality so pot luck if you get a reasonably good one or just a shoddy one.

On the inside one needs a spacer washer usually to prevent hub/cassette rub on the drop out, a torque arm is more then a spacer/washer in size so even on the inside needs a washer between it and the motor.

No different to other electrical appliances, a short will simply cause the RCD tripping (30ma) so as Ben says it is either the charger or battery charge point causing the issue. Only needs on minute strand of wire or a bit of insulation wear between the two to occur.

I would go one further and temporary wire up a meter to 100% watch what the voltage does. The issue may be controller or display related if the V's hold up.

How many wires or pins for the motor axle cable ?
