    48V+ Controller and LCD recommendations

    The Kunray controller showed up today and I took a look inside it, however they've got the FETs held to the heat spreader with a pressure clip / bar that would have been a royal pain to remove and pull it out. It is a 9 FET controller and for this particular scooter it was nearly 100% plug and...

    48V+ Controller and LCD recommendations

    Thanks for the info! I wasn't aware of which controllers had open source firmware available for them so that's really helpful. I wanted to get an order in that I'd receive quickly so I actually ordered this one up from Amazon yesterday...

    48V+ Controller and LCD recommendations

    I've got a Freego scooter that the controller finally gave up the ghost, one of the STP75NF75 fets went bad and I think I may have wrecked the trace on it when removing it. The stock controller had a few nice things that I can do without; automatic headlamp and 2 switched outputs. One output...

    Freego ES-10S issues and modification questions

    As I've done a little digging myself beyond the Grinfineon 25A controller I mentioned above, I came across this combo that looked fairly decent and only 2.5" longer than the current controller. I do like the ability to program it from an app on my phone, but not convinced I could read that...

    Freego ES-10S issues and modification questions

    I took a look at the Grifineon 25A controller and CA V3 setup at ebikes.ca and they look like they'd work nicely. I've looked at the phaserunners they have and am really attracted to the size for the current they can handle but I'm not sure it's worth the 2x price over the Grifineon unit...

    Freego ES-10S issues and modification questions

    This happened from day 1 of getting the scooter with no shunt modifications or changes to the parameters for the controller (via the LCD). The factory setting per the guide for max current was 12A, and I did try going down to 10A and up to 20A but it didn't seem to have an effect as I still got...

    Freego ES-10S issues and modification questions

    I purchased a Freego FS-10S (Really a ES-10S they renamed to FS for some reason in the USA) back in 2019 from Amazon. It was returned and because of the issues I had out of box I got it for really cheap, about $375. It's a 48V (13S4P battery pack rated at 10.4Ah / 499.2Wh) scooter with what...
