    modifying a 48v controller to run a 48v motor from a 36v battery

    Thanks JHRUK, it does help, I now know I was following the right pin ! D8VEH, spot on ! I traced the board links underneath and it did take me over to the grey wire. Here's another photo with the hidden lines shown and my estimate of the circuit from the suggestions. Is it 7501 and...

    modifying a 48v controller to run a 48v motor from a 36v battery

    I've had a good look at the controller now, and the chip is the same one as in Van Dalen's circuit diagram, an X8M06. I'm trying to trace the under voltage detection pin 12, but I'm not certain that I've got the orientation of the chip right with the diagram. The chip has a circle corner marker...

    modifying a 48v controller to run a 48v motor from a 36v battery

    That's excellent, thanks for the very rapid and informative reply. I've compared the pictures with my own controller and I think it's going to need bit of tracing. Here's the photos of my unit: It sounds as though it should be an easy mod, just what I was hoping for. I don't want to buy...

    modifying a 48v controller to run a 48v motor from a 36v battery

    I have a 1000w 48v brushless rear hub motor with the supplied 48v 1000w controller. I also already have a 36v 12ah lithium-ion battery pack and charger which I`d like to use with it for now (while I save more money up !) Reading the forum, I understand that the motor should work ok with...
