running a satnav from a 6v battery

[lukamon]

the output of the cig lighter plug for my tomtom says 5.8v, so assuming i can hook up a connector to some wires, will a 6v bike run it? or will the charging voltage of the bike be too high?

cheers, luke.

6v should be OK but personally I'd stick a regulator circuit in there to make sure it doesn't go above that.

It also may well be an AC system so you need a capacitor and some diodes in there to smooth it too. Even if not, they would still be a good idea.

Use something like this:

I think 5 volts would be enough to charge it actually.

Are you thinking of installing a Cig lighter socket on your bike. Or are you planning on cutting the Cig lighter plug off the Sat Nav wiring, and wiring it directly to the 6v supply?
