I see your point. The battery monitor circuit is mounted into a plastic box,http://www.cjdawson76.btinternet.co.uk/images/astronomy_batterymonitorf

That shows your 'voltmeter' but it doesn't show the loads you connect to
the battery, and that matters; see below.
it's connected to a little Fuse board circuit, which the other devices are
connected to.
So basically it goes, Battery down a 3 Meter cable to the "Fuse board".
Then in parrellel to the Battery monitor, Telescope, and Dew heater. The
battery monitor is in the same box as the Fuse board and the dew heater
controller. The heater controller feeds a 5 meter cable that connects to the
heating element. The telescope is connected to the Fuse board via a 5 Meter
cable as well. Something like this...
Battery --------> Fuse Board --> Battery Monitor
--> PWM (K8004) ------> Heating Element
--------------------------> Telescope
It's as close as I can get it to the battery terminals without putting the
circuit on the battery (which I don't really want to do)
That's exactly what I was thinking of. It would be on a par with putting aMy thought on this is to place a kind of Ammeter into the circuit, that
will adjust the value of VR1, in accordance to the amount of current
drawn through the circuit. Changes in current would would effect this
part of the circuit, and continuously trim the battery meter, so that
the readout remains stable. (and hopefully correct)
No, all that would do is to alter the calibration of your 'voltmeter' so
that 10 V appeared to be 12 V. I don't think you would be satisfied with
that!
spring into a pully system to keep the tension constant.
And ideas for how to do this?
