Battery Monitoring

Tried to fall back and punt, but got blocked. If your talking about football punting from five yards back is not enough. Not sure if soccer has punters dont follow it.
Punt distance is measured from the line of scrimmage not from where the punter kicks the ball.

Sometimes you have to have a reference, so all things are equal.

Muddling is earned. It is a RIGHT. Younger pretenders need to be admonished.

The OP should fall back five and punt...

Individual AMPERAGE values can be measured and interpolated. Say both batteries are at 50%. Voltage is applied. One battery reads significantly lower amperage starting out but then refuses to taper off anywhere near as much as the first battery.

What is that telling you?

After the trip you could charge and separate. Then just check voltage with your multimeter. Not sure this is the best way to determine if one is getting weak. Hydrometer is a better indicator but a bit of a pain.

Do you feel you are having trouble now? What are the charging habits while camped or in storage? What converter are you charging with? anything else?

If the switch is in either the #1 or #2 position, the parallel tie between the two 12v batteries is severed. If the switch is in the #1&2 position, the parallel link is maintained. It's no different than switching to "both" in order to supplement a low soc boat engine starter battery with the on-board house battery.

In all three cases, whether switched to #1, #2, or #1&2, power is available to the meter, just as an inverter would be if connected to the common stud on the switch.

I'm not sure that if one battery was "carrying" the other a little, it would take time to see that. I have seen my batteries hold different voltages, even when wired together. And if there was a rather large discrepancy in voltages between the two, the stronger battery would likely draw the weaker battery right down.

I am muddled in my thinking whether the switch takes each one separated or takes the voltage of each one while still connected in parallel.

I was thinking about the Blue sea switch. My reasoning (which could be wrong) I thought by being able to check each voltage separately I could see if one battery was getting weak. Didn't think about having to wait for them to stabilize before checking. I know connected in Parallel voltage same current increases

No. You would have to separate the two batteries and wait till their individual voltages settled, and then take each one's.

If looking for a bad cell, an hydrometer would be the answer.

You would have to break the connection between the 2 batteries to measure individual voltages otherwise the voltage is the same acroos the 2 batteries. :(

In parallel the voltage will be same.
Second meter or switch is redundant.
