The larger the conductor, the less resistance = more current flow.
1ga is good choice for the longer cable runs of trunked batteries.
1ga terminals should be common enough. Even 1/0 to 0ga lugs and
terminals should be available locally. Try truck shops or the local
trendy car stereo store (ask for the most "radical gnarly terminal
size". add/remove the gnarly descriptive if the gauge looks too
small/big).
The standard or common sized stud sizes are 1/4 (not in your
application), 5/16 and 3/8". A quick poll of engineer hands here says
5/16" is more common, while half say they are interchangeable (meaning
get a lug for a 3/8" stud). Your call (they are still arguing...I
don't involve myself in such behavior =) or maybe someone can
contribute or verify this info.
Soldering is always preferred over crimp/clamp on types. Even with the
non-solder crimp and clamp on type lugs/terminals you should not avoid
tinning the cable. It will work if not tinned but it is guaranteed it
will haunt you some time down the road. Cables should be tinned so
that all the strands are bonded together and no copper is exposed.
[quick tips working with large dia cables. clean copper is a must.
resin or resin core solder is a must. tarnished copper *cannot* be
soldered. if solder wont stick try dipping the copper into
hydrochloric acid before a thorough cleaning. Cable lugs can be
soldered with the stripped and clean cable end inserted and heated
over a "clean" burning gas flame, then running solder into the lug
when it gets hot enough. When a soldering iron is absolutely
necessary and your iron lacks enough wattage to melt the solder over
the cable, try heating the lug over the stove, but use your iron to
maintain the heat].
