I believe that I was taught that all things being equal, that stranded wire would carry more current than solid wire ? Is that true or am I being misled ?

I won't annoy you by looking it up.

You're being misled... Given the same size wire, solid wire will carry slightly more current than stranded due to the spaces between the strands reducing the capacity. In practical use, the difference is not a significant factor in deciding which is the best choice for a given application.

Also , I am sitting here ordering a 200 amp lithium battery and the proper charger , what do a shunt do and why do I need one ?. The battery is on the way , $ 600 bucks , wow , Boy I hope they do not quit social security until I get this paid for !

A shunt is a small resistance inserted in line with the load that allows a much smaller meter to indirectly read the load without the total current passing through the meter circuitry. The meter simply reads across the shunt and uses a calibrated multiplier for the reading.

A shunt is used in conjunction with a meter to indicate what is going on with the battery.
Which will indicate the amps put into the battery, amps taken out, state of charge etc.

More wires give more surfaces for current to travel on. Finer the strands the greater number of surfaces. Considering the same size of wires.

ok if a stranded and solid are the SAME wire gauge, current carrying capability is the SAME. e.g. both AWG 14.

Current does not travel on the wire surface until the frequency gets to about 20 KHz. It is not an issue for power.

A shunt allows you to measure current flow. So you can tell how much coming out of or going in to your battery. If you don't plan on monitoring these things then you can do without it.
