    Kelly KLS4812S Programming interface cable?

    Hi, sorry for yet another controller thread. I am looking for controller when this Kelly KLS4812S popped up locally for sale. It's apparently used only for a week, size is pretty compact and it seems to be quite better than generic chinese controllers. Since it's programmable, I don't know...

    XLD Brainpower LSD149 - Remove LVC

    I've bought a XLD Brainpower LSD149 controller. On the case, lower voltage is indicated as 42V for 48V battery. That's 3.2v per cell. I have Samsung 50E that can go safely lower than that so I want to lower or ideally remove Low Voltage Cut out entirely. I also have Bluetooth BMS so I can...

    I did a stupid thing... I have this style of rear hub motor. Has 500w stamped on it but I see same motor being sold as 500-1500w usually. Been using it for 9 000km - 2 years without any problems (bought it used, not sure how much it did before but it was nearly new). I wanted to upgrade phase...
