Batt hookup Money saving tip

Figured out lately that since i need a very long #4 battery lead, that the cheapest way to get the number of feet i need is to buy a set of Jumper cables

at my local Rural King store.

#4 Hobart welding cable is $3.49 PER FOOT

#4 (16) Foot Jumper cables $11.99 (32) Feet total feet!!

I would be skeptical. Actually test the resistance against known-good wire.

My digital Ohm meter comes up with nothing but Zeros.........

BUT I admit I was taken.

ALUMINUM Core wire.

I'm out $11.99 in the grand scale of things, Its not the end of the world.


To ADMIN here I wish i could edit my original Post to warn people.

Any lower-cost options in the electronics / DC electrics world need to approach by default assuming it's a scam.

What you have is 4AWG, not 4/0 (0000). Huge difference. You couldn't buy 2' of 4/0 jumper cable for $12.

The gear that you would use to measure DC resistance in relatively short lengths of wire is way beyond your typical $49 VOM.

I almost fell into the aluminum cored wire mistake. Some eBay and Amazon sellers are not very straightforward about the composition of the wire they are selling.

I found some all copper 1/0 "superflex" cable on a solar job last year. It was kind of expensive but was SOOOOOO much easier to work with than typical 1/0 copper.

well i completely (almost) made up for my $11 mistake.

I work at a RV/camper dealership part time. and get some good deals sometimes.
For legal reasons the dealership will NOT install a new plug end on a Used cord on any camper/RV they are selling. They replace the entire cord.
I was
Given for FREE a 30 foot or so 50 amp cord with no ends.
So I ended up with over 100 feet of #6 Multistrand COPPER wire
#6 is not my first choice but it will work since there will be so little draw on everything.
