Battery cable selection

I am putting two 12V batteries together
http://www.batterymart.com/p-hawker-...t-battery.html
to make a 24V battery.

What size cable should I use to make the serial connection?

Same size as the main battery cable. It will see the same amperage.

no, it will see half the amperage at same wattage

Huh? You are joking...right?

No Jim was correct. The amperage is the same.

It is a series circuit - the amperage is the same throughout.

If you were wiring two batteries in parallel (and getting 12 volts from the
pair), then each battery would deliver 1/2 the amps (approx.)

I guess that should read Kirchhof, should anyone wish to google it up.
For one example, see http://www.allaboutcircuits.com/vol_1/chpt_6/4.html

Hm. Actually it is Kirchhoff.
Nothing like German for spelling confusion.

not sooo fast, Mr.L'ectrzity!

supposed this guy got some bargain instuments (or radios, or starter or
whatever else) BUT these are 24 volt units then you could come to this
conclusion to join two batteries. In this case you will have half of the
current flow compared to a 12V system. So you can use half the cross section
of your cabling. Basic electics.
