It will run for 11 1/2 hours on a single charge then you get to rest for 2 hours while it charges. For longer times you will need to purchase an external power lead - mini usb connection. At the other end you will need a power source which must *never* be appreciably over 5V for any length of time. Safest bet is a regulated source. You can buy these (do a google search - I've got the link somewhere but can't lay my hands on it just now) or make one yourself if you can (cheaper).CycleRon said:Hi guy's
I"ve been looking at this GPS for a couple days, and have some concerns whether it will do what I would like. I'm thinking of using it on the GVBR, would it be able to record the whole ride or would it have to be saved some how. The other concern is the battery life, where to recharge batteries or use spares.
Any suggestioins would be of help. I klnow it will be of some hel;p preparing for the ride.

For the latter I would suggest a 2.5 to 5AH LiIon pack in a small bag velco'ed to the top tube and a reg shrunk into the lead. Mini USB leads are $9 from WES.
For long rides you can dump this 11 hours before the end of the ride.
The adapter that comes with the unit is a 5V regulated switch mode wall wart rated at 400mA. A ready solution to the reg is a switch mode DC converter made by Duratech. It's rated at 5V 600mA with an input voltage range of 9 to 18V. Use 3 Lion cells and this reg will suck them dry!!. Be warned. You may need a low voltage cutoff to prevent cell damage.
The model number is SCW03A-05. Distributor is Electus, ph 1300 738555. They are retailed by Jaycar, cat number MP3204, $32.95.
I use these to power Bluetooth transmitters in earthmoving equipment and they have been quite reliable so far, so I expect them to be fine for bicycle touring.
