Resurrecting this one from the dead. I have a B&M Lumotec IQ Cyo LED headlight leftover from when I had a dynamo generator front hub. Would like to put it back into service using battery power. Is it as simple as connecting a 6 volt battery pack of the required capacity to keep it powered as long I need it to between charges? Would this work? http://www.batteryspace.com/waterbot...bikelight.aspx
