    hey folks,
    Anyone out there upgraded their 80's Voltage Reg to a modern one? What do I need to know? I have recently bought a Lithium ion battery and I've heard it's a good idea to upgrade the VR. Where can I get one that will suit?

    Super helpful thanks, I went out for the first ride today since installing the battery and everything worked fine.
    Thanks again,
    Rowan.

    There are batteries that are intended to be run on racing machines with a total-loss electrical system (charging is only done by a dedicated plug-in charger). Those will not have a BMS (battery monitoring system/ charging computer) and should not be charged with an alternator.
