    Problem with KT 20A sinewave controllers?

    Update: repair worked great. Can recommend using the emergency light enclosures as controller boxes. Ethernet cable wiring also worked great first time, and looks really neat. Much better than all that spaghetti, and fiddly JST plugs. Gave the machine a couple of really good long test rides, and...

    Problem with KT 20A sinewave controllers?

    Hmmmm still not really finding anything in those results, seems like there is a pretty traditional aspect ratio for junction boxes, can't see any that are long and narrow as I need. HOWEVER...I did have a brainwave...those LED "bulkhead" emergency lights are in just the right sized box, and IP...

    Problem with KT 20A sinewave controllers?

    Thanks for your help guys. We decided to use a big 45A controller and restrict it to 20A, because this is the guy's daily commuter ride, he lives up a big hill and he ain't gonna be doing no more pedalling than he does now! So the next problem I have is finding a good sized, waterproof box to...

    Problem with KT 20A sinewave controllers?

    Right on...so the KT 20A 6-FET models are not, in reality, able to really sustain 20A? That is just bloody annoying! I had one apart and checked the MOSFET model number - they are TK150E09NE - searching that indicates they should be 150A parts - so why should they fail short at just 20A? Even...

    Problem with KT 20A sinewave controllers?

    Hi guys, I've recently been having a total nightmare with a customer's Gunai 24" fat tyre folding ebike. Initially, it had a lot of problems with water damage to the wiring, which I thought I would solve for good by replacing the controller, display, all connectors, and moving the controller up...
