    Prodeco Phantom X2

    That is great Rob. I am interested in that. Perhaps you could also open up to answer questions that are email to you too? and post the transcript of the chat on your website, on your facebook page, and here, so people who are not able to attend, can review your q and a. thanks!

    Izip conversion from 36v to 60v

    This guys spliced in a 24volt battery in series to the 36volt battery that came with his Currie Izip Zuma to convert it from 36volt to a 60volt power source. He also swapped out the controller. The Izip lithium battery packs have 4 prong connection that is not registering any voltage with volt...

    You think it's a good deal?? cheap A123 18650

    I was thinking that 3D printing with ABS plastic may be useful for fabricating custom cell holders. They could be built with space for mounting conducting metal that can also have tech to hold them together by pressure. they could also be designed with multiple vent holes which may be useful as...

    Tartaruga Semi Recumbent electric assist (import from Japan)

    This is a folding version of the Tartaruga, which is made in Japan. I think this would make an interesting platform for an electri hub motor system.. could even do a two wheel matching hub motor system because the wheels are the same size. O1mldQIhk-I

    variable regen throttle and controller for ebikes.

    "Modded 9C with modded 12 fet infineon"?? I see infineon is probably the controller. what is modded 9C?? "18S lipo - 5kw peak"? 18 cell lithium (LiFePO4??) ? are you running any parallel cells? you using a BMS? I presume 18 cells at 4.19 volts in series for optimum voltage of about 75 volts? 6...

    Wiring diagram/graphics for brushless motor full revolution

    Thanks "whatever". In a way the hall sensor is kind of like a diode that has a switch in it that is controlled by magnetic fields? So hall sensors consume about 1v of some small amount of current, even when in off position? I suppose this is one of the sources of drain on battery when...

    Wiring diagram/graphics for brushless motor full revolution

    Thanks for the links. the "power" from all the hall sensors are connected together, all the "ground" wires coming from the hall sensors are connected together, and signal wire from each hall sensor seperately?

    universal test device 4 brushless & brushed motor controler

    So far, of the couple videos I have seen of this tester being used, it have not shown what it looks like when testing a working controller or throttle. And the people using it seem to not be sure if it is working or that it is connected correctly. I am hoping I will see someone post a video that...

    lithium batteries bad TV reporting

    thanks for posting the video. I was thinking that a way to make them safer is to place the charger and battery on top of something fire prroof, like a a slab of ceramic tile..or on ceramic floor, like many people have in a bathroom or kitchen.. and perhaps someone can build a device that can...
