Sorry to spam the board with my messages. I have just spotted this on eBay:
This person has stolen my photos and content of my listings, and I advise that you avoid this person. If not for this reason alone, for the large number of negative feedbacks (33 in fact) that this seller has. I did not give this seller any permission to use my photo or the content of my listing. This is a bad seller, and given the negative feedback of this guy, its no surprise! He's obviously one to try and make a fast buck!
Re: 6V and 12V for Des
On a lighter note, I have now tested 6V on the battery. Although the tracker works on a 6V battery, if the voltage drops much below 6V (due to loss of charge from use), the tracker will stop working since the output voltage will not be high enough. In conclusion, I suggest you use a 12V battery.
