Hello, I do not need benchtop PSU, I need 5kW motor controller... My motor has 3 hall effect sensors..

Hello, I've built electric scooter using 1.5kW 11" hub motor. It rides very well, but I need more power 8) The battery is 13s4p of molicel p42A (delivering max 45A per piece) At the moment, I'm using 1800W controller, that the motor came with. I'm looking into purchasing some kind of...

Yeah I dont know why heating controller would help the problem, but I'm guessing the UART communication is broken between the LCD and controller... ...

Hello, I've found the issue! FINALLY :p As it turns out, noone was right, it is not the controller nor the battery problem. I've had a chance to test my friend's LCD (with throttle), and it works flawlessly with his LCD (brand new one). Now I've started to troubleshoot the problem, and my...

I've thought about that.. I've already soldered tohether all the phase wires, and hall effect sensor wires. didnt work, so I've tried: soldering brake lines and LCD directly without connectors.. Same problem persists on and on.....

Thank you for your reply.. I should mention, that the cutoff happens independantly of the motor load.. So even if I run the motor in air (no load), the cutoff happens aswell! So when running the motor without the load, the voltage dip is around 1V, so that disproves the battery problems (I...

Hello, Yep, the controller is cheap 1500W one.. I seriously doubt that the battery is the issue. Like I said, when I start driving (cold controller), the cut off's happen. When I drive for 10 minutes the controller warms up, and it start's to work flawlessly.. This theory is proven with...

Hello, first of all, thank you for your reply.. The controller is 48V, 30A, so 1500W I don't think the problem is in the battery. I've rode more than 1000Km, with no problems with this battery. than the problem started to appear (only after 1000 Kilometers) I have 4 cells parallel, and each...

Hello fellow EV enthusiasts. I've built an electric scooter, and rode it for 1500km. Now after 1500km, the controller started to cut-out, when I'm starting to ride (cold controller). I've heated the controller with heat gun, and it works flawlessly, but when I try to ride it from cold...
