Cheers,
If you want to compare weights, I ordered 20 feet of #4 CCA
(copper-covered alu) wire from Perihelion and Eric Jones. I expect to
install a 17Ah battery under one of five compartments built under the
extended bulkhead 'shelf'
It weighs 48.75 gm/ft. I was going to use #4 welding cable (rubber-covered)
which is 127gm/ft - because of its flexibility and rather innocuous smoke
when heated (archives). I don't know the weight /foot of #4aircraft cable
but it may be determined I'm sure.
The length involved may be less than 20 feet, but that too I
leave to you. The advantages beyond the weight are (1) more flexible than
a/c cable; (2) better insulation than welding cable (a/c standard); (3)
yellow colour makes it more readily obvious; (4) fits neatly in 12mm/half
inch copper tubing for nearby ground - watch the chafing..; (5) Eric is
great to deal with and has excellent installation advice.
Minor disadvantages :
(1) More expensive - stop smoking, nothing much on a big ship;
(2) slightly larger - see 4 above.
I feel better about shifting the battery with this material, but of course
you are the final judge. Nevertheless, maximum time of starter engagement
must be calculated when using aft battery........
