    Charging: What can be communicated on the CCS chargers?

    I am wondering. Why do we need to have RFID fobs and apps etc. to charge our cars? When you plug in it just confirms that payment will be made. So the local motor department just sends a "1" and then it starts charging, and when done charging it requests payment. Then we just need to plug in...

    Hmm.. Thunderskyd/Ningbo 60V charger hacking?

    Four months ago the charger got a problem with the electronics that controls the 12V fan, so I disassembled it and tried a couple of things without any luck. At the end I just shorted it out, so the fan always runs when the power is on :( Not optimal but it works. Anyways, I found some jumpers...

    How to connect an alarm to battery?

    I'm going to connect a GPS alarm on my 60V scooter. Do i just find a random place where the voltage is 12V and then connect it? Or is there a better way? I guess it would be better with a 60V-12V converter, if that exists.

    Why battery packs?

    I imagine that there is a huge resistance, when using a battery pack, because all of these small cells are in series or parallel. Is it impossible to take a small cell and make them 100 times bigger? I think it is crazy to have battery packs as big as 60V40Ah. Can't they just make a cell that is...

    Where to get cheap controller for my XM-4000-LI/erider ?

    Erider 4000W scooter reverses and acts wierd.

    When i turn the key, sometimes it does not respond to throttle, other times it reverses, and then forwards, somestimes it keeps reversing, and it's getting worse. When it does this, it ignores safety features. So when i brake or put down kickstand, it does not cut off the power, it just keeps on...
