Re: Electric fishing canoe

wow, amazing reduction in consumption. I'll conduct the experiment if you are kind enough to supply the gear - thanks ol'mate. my biggest enemy is wind... there is a river close by with no current, but it will also need to be dead still. The prop is the standard 2 blade model it came with.... I'll s...

Re: Electric fishing canoe

I sure like the looks of this! Any mods done on the outboard motor (either with the prop or the motor controller) or is it complete stock? I'm also curious if you have a watt meter or amp-hour meter to get an idea of your consumption in Wh/km at different cruising speeds. We have lots of firsthand ...

Electric fishing canoe

Recently completed a project I started many years ago. It was more of a restoration job, given the amount I had used it prior to having finished it all those years ago. Hull is plywood coated in Epoxy and 2-pac painted. 12V motor and LiFe pack - forward steering via the foot pedals, and I have rigge...

Building a few small 36V packs at the moment, using 30Q cells - spotwelding 0.1mm copper with the DN10 welder and custom timing circuit. I used the cardboard insulators for the first time, and would highly recommend in the case of gluing a pack together. 20181130_132205.jpg 20181218_094405.jpg 20181...

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.

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...

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.

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...

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.

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.
