Re: Pneumatic spot welder sticks to cells

Tips need to be clean, and you might try to wait a few seconds for the weld to cool before releasing the pressure of the electrodes.

Need to apply sufficient pressure - to avoid sparking and hot welds from arcing.And correct power settings will also help.

Re: Mobipus Controllers

Regen has an over-riding off or on in the top level setting... along with a few other settings including voltage calibration. You don't really need to spend more than an hour with these settings unlocked. Regen variables can be adjusted freely when using the standard password for programming... and ...

Re: Mobipus Controllers

These are epic controllers. Programming and interface with PC is as easy as it could be, given the complexity of the unit. Setup requires a level of experimentation for the noob obviously, and as Sam said, this could be very dangerous for someone 'tinkering' with stuff when not experienced enough. W...

Re: Mobipus Controllers

a one hour ticket from the factory ? To unlock the top level of settings (which includes the last option for regen to work) a time activated key needs to be submitted, which gives you one hour in this unlocked mode.

Re: Mobipus Controllers

I recently finished this off for a friend - has the Mobipus 200A The BMS is limiting to 150A...(set at 140) and phase amps to 240.... so not really getting the most out of it, but it's still a fair amount of power, and really great variable regen. A lot of settings, and some could only be unlocked w...

Re: CA faulty after LVC shutdown

--internal regulator in the CA is not passing voltage as it should, so the backlight comes on but no voltage gets to the MCU/etc. If this is the case, there is an aux voltage input on the CA PCB that lets you use a different power supply (12v, for instance) to run the CA from. It'll still measure t...

CA faulty after LVC shutdown

Please help. A bike I recently finished for a friend, hit LVC whilst under full load... I'm suspecting by the BMS. At this point the Cycle Analyst also stopped functioning. The Cycle Analyst stands alone, and uses a 3rd party shunt. For speed pickup I tapped a hall signal, and power is activated via...

Re: Stealth DIY Build

Many have done so. Heaps of builds here... and if you are going to build a bike you are going to need to spend a lot of time reading these forums.

You can build a much better bike than a stealth though... something with good moto rims and tires and at least double the power of a stealth.

Re: Battery and electronic box, can you actually bend what you draw in sheet metal

make it out of a thermoplastic like polypropylene or HDPE... easy to cut out and you can fold it and shape it using a heat gun or heating element to soften it.

Re: Spot welding fuses to individual 18650 cells?

ok I accept that. But I still don't see the point in welding fuse wire to the cells. It's actually very rare that a single cell would 'blow'... Almost all battery DIY major fails are related to mechanical failure, and by this I mean all types of physical damage - from wiring rubbing or some type of ...
