I run the Ulsteroid on 12v, because it was already converted when we bought it. I am impressed by the starter performance and instant starting, noticeably better than typical starting on 6v. The other useful thing is that I can use a motorcycle battery, which is relatively cheap and lightweight. Additionally it is easy to get flasher units which have the 'hazard warning' facility. I have not found 6v flashers with this feature. Also the lower current required from the dynamo is likely to keep it serviceable for longer, because the heating effect at a typical load is only one quarter (square of current multiplied by resistance) of what it would be at 6v. I do however run the Chummy on 6v. There are no starting problems with a good magneto: just turn the handle! And the satnav is happy on 6v.
