Storm,

That's exactly what I do.

Man...I read Roland's post about how many motor amps vs. battery amps he draws. I had no idea the difference between the two was so drastic.

My little Beetle doesn't have much more room for gauges. I'm probably going to just move the ammeter to the motor. If I don't over-draw the motor, then I automatically won't over-draw the batteries (as long as I stay within the pack's minimum safe voltage).

The flooded batteries don't like highamperage draws. I keep the draw below 250Amps so as not to beat up thebatteries. I don't know what good use I'd make of motor amps. Probably wouldbe interesting to see the relation to battery amps. I use the battery ampsto control my right foot until the state of charge gets lower, Then I usethe voltmeter to control my right foot.

Take a lesson from Dennis's S10, use one gauge for 2 measurements, one from
the battery and one from the motor, all you need is a 2nd shunt and a switch
to change between the 2 shunts.

Thanks Rush, that's a great idea.
