Battery voltage, switches and cut out

[Charles Levien]

I have to say I think Bryan is right -- change your heads to LED. My Dynamo is set to charge around 2.5 amps on "high" and this is plenty to keep the the battery well charged. Interestingly, I do find less battery terminal corrosion using LEDs but you have to watch electrolyte level in your battery if running a lot of the time with lights on, as we did recently on a five week European tour.
Hope this is helpful
