Re: (ET) Battery readout

I've thought about this a lot. What you really need is not the individual voltage of the battery, but the *difference* in voltage between each battery.
If all 6 drop to 6.0 volts while going up a hill, that's fine. However if 5 are at 6 and one is at 5.7, you would want to know that one of the batteries is low.
I'd be happy with a simple red/green LED that would be green as long as the battery voltages were within a range of say .2 volts. If the range is different, the red light comes on and it's time to check the batteries.

   Wouldn't it be great to have instant dashboard readout of the
voltage on each battery! This could be done with the little bar LCD
meters. Multiconductor cable with AWG 22 wire would be sufficient for
the hookup. Any weak or undercharged battery would be evident right
away. But where do you get these six channel meters?
   Its time consuming to measure the voltage of each battery
individually, and/or use a hydrometer. I make myself do it every month
or so, but I hate it. My "fuel" current meter has never indicated
anything useful to me. It may have dirty connections because it never
reads "full".
   I realize I could do this with one meter and a rotary switch, but
I'd like to see the bars of all six batteries at once for quick
comparison.
