That 'plastic' you found is called Potting Resin. It's used for a variety of things like protecting the electronics against vibration, and it conducts heat away from the components making the controller run cooler. It's a sign the controller was built as a quality unit (also indicated by the waterproof connectors the controller used).
It is very simple and you gave the answer, mosfest are "taps", turn the tap on and power gets throught to the connector, try connect the mosfet on, as it is low corrent you can use your finger, put your finger in the mosfet connectors and put multimeter in the main positive and negative ( instead your finger use any electric wire or tool). Try at your own risc.
If you just make a small hole at the back, you can use a screwdriver to loosen the battery without damage and the lock will still work normally. You're not going to make a hole in the side if you demolish the whole thing. Those three thin wires on the motor are for a temperature sensor, there are no hall censors in these wheels and the throttle has 3 wires and not 2.
Not sure about that hole, you mean from the front of the "neck" of the scooter? I'm pretty sure those thin wires from the motor are not temp sensors, the ESC really need a good grasp of the position of the wheel at low speeds especially, so it's very likely an encoded angular sensor of some kind. And yes, the throttle is three-wire, I think I show that in the video as well.
Hi, I’m new in diy e-scooter, mine was the bottom part is fully welded, I have no idea for now how to remove the battery with its bms. Do you know a model like this? Thank in advance
Good video compared to the other videos out there that are unfortunately mostly pure trashy rubbish. If you gain more insights into the inner workings, like debugging the CAN bus or discover that the motor is really speaking 1-wire, etc., I’d love to see more of your discoveries. Thank you!
To know how the inner workings of that clock work someone would need some knowledge in embedded systems as well as the scooter. You could hook up a logic analyzer and try to figure out what it does. Or extract and reverse engineer the firmware which could get harder if they enabled the protection. It would be a shame if a broken scooter randomly appears (legally) in front of my door :D
@@_DSch I’m thinking ideally logic analyzer, then replace the firmware with something homegrown. I very much doubt they’ve added security keys to all components in the way Apple has done. Likely only the MCU has locked firmware that could be erased if not backed up.
It would probably be possible to hack the ESC if one could get that resin away without damaging the components, but then you would also have to be lucky enough that they some standard hw for the electronics so that you can just use some open source software to flash onto it. I sort of doubt that. Hacking the CAN protocol controlling the ESC might of course be possible, but if it's encrypted in any slightly serious way that will be a loooong task.
is it that if you will use a chisel on top of the battery it can help to remove the battery? somehow it will puch battery down a be release from the latch.
@@surplusstock8778 If you watch the video, you can see that it’s not usable at all. Everything from the battery management to the motor controller are all on their own communication bus, it’ll cost more to replace the non-functioning parts than it would to purchase an inexpensive scooter.
Yes, they've done a good job locking it down. You would need to replace the motor controller which will cost you like $200 I guess. Great quality scooter though
@@pashkaS54can convert it for under 60 bucks with a $30. Controller. These. If you don't know scooter wiring then yes you're going to have to buy inexpensive scooters used or broken. It pays to have talent my good man.. you can get any of these scooters working from any company if you understand the wiring and basic mechanical functions.. I have the joy of owning one of these one several others brands, Bird, Spin, Wheels, Link, to name a few.. thanks to my basic knowledge of motor controllers and battery wiring can get any of these working NP..

If you use a pry bar you can just break the the lock and take the battery out very simple

Looks like he's going to smoke the scooter

well, that will be pretty hard, it's a really sturdy piece of hardware. Much easier to just drill like I showed.
@@Oxiemannen pied de biche
what nuts are they using on the motors and how did u get them off
burin
Has this got one gps on the neck of the scooter?
Well, yes, that's where the central control unit is placed
So only two screws preventing it from going missing?seems odd
