    How do I switch on this SCR?

    Hi guys, I recently received a SCR (model "KP300A") after a lengthy wait from the Chinese postal service to Australia. Here's a picture of what I expected to receive: Here's what I actually received: Can you spot the difference? It seems the thyristor I received is missing the gate...

    Headway 10Ah cell problem

    Hello all, I recently put together a 24S2P (72V, 20Ah) LiFePo4 pack made up of 10Ah Headway cells for an e-bike project. It is connected to a BMS that has performed flawlessly in the past. After the pack (about 50% charged) was installed into the bike, the bike worked great. Then I charged it...

    Connecting the Cycle Analyst to a Generic Controller

    Hi all, After salvaging the phase, hall, and battery wires from a dead controller, I decided to also salvage the Cycle Analyst connector cable and attempt to connect the CA to a cheap Chinese controller I got off eBay for about $30. So far I have soldered the CA positive onto a point on the...

    EM3ev Infineon Controller Regen

    Hello ES members, I recently received a 72V 40A Infineon controller purchased from EM3ev. Almost everything on it works great e.g. cruise, 3 speed switch, e-brake etc. The hall and phase wires were a bit short but I replaced them with a longer wiring harness from my dead controller. Anyway...

    Hub Motor Restoration & Hall Sensor Replacment

    A hall sensor in my Crystalyte X5304 died either due to rust/corrosion/moisture or a fault in the controller or wiring. Upon opening it I found out it was full of rust, so I figured I might as well clean that off while I have the motor open. Admittedly I didn't get the motor as clean/rust-free...

    Infineon 40A controller failure

    Hi guys, I have a sensored Infineon 40A controller (12xIRFB4110), 36-72V connected to a Crystalyte X5304 and running at ~72V. It has just up and died without warning. The controller still powers up and activates the CA, but there seems to be no power going to the hub motor. A sensor got fried...

    The Handcycle Sidecar (Mk II)

    There doesn't seem to be many (if any) sidecars here on the ES forums so I thought I'd share the photos of how mine was constructed by myself and my brother.

    Crystalyte X5304 Hall Sensors Shorting?

    Hello all! I have relied on the endless-sphere forums for many years now every time something goes wrong with one of my electric bikes or trikes (usually BMS problems), but now I seem to have a problem I cannot find a definitive answer to. Last Thursday night my Crystalyte X5304 on my...
