Ok, so I gave up with the calculations on the Voltage monitoring page and I fitted a 10k Variable pot resistor like the one attached. It is a no drift type so hot and cold in regular conditions does not effect the resistence. When I was finished, it measured at 3080Ohms.
Hope this helps anyone else having simular issues.
Perhaps you are looking for more details to respond to this one.
I am running a 3S lipo battery. I have solded into the board the balance connector. Grnd is Grnd, an0 = 4v and an1=8v and an2=12v. I have soldered in the 3 3.9k resistors and measured them to make sure they were the correct values as per the howto.

Morning,
ok, so have done some more homework. Here's how I propose to do it without changing any code.
My Target is 4.58V as I understand it.
I used http://www.raltron.com/cust/tools/voltage_divider.asp to calculate the ohm rating for R2 which is 5.710ohms.
Unfortunately I could not find a 5.7k resistor so I used http://www.raltron.com/cust/tools/parallel_resistance.asp to calculate the closest possible match that I can get. 24k + 7.5k in parallel gives me 5.71ohms.
So I will try to find two of these resistors and solder them in and test.
If I am going to be blowing up my APM, please warn me, I will certainly read all of your posts tomorrow evening when I attempt this.
Regards,
Solo.

I would really appriciate a response on this one.
