Build your own cables cheap by using welding cable with copper ends/connections. Thanks for the schematic, I never knew....

@LoneOarman Hi, thanks for the tip! I do have some extra welding cable that would work for this, I am just lacking on connectors. As I think about it, I could use a very small piece of copper pipe cut down for a end, and then crimp that on my connector. All of the parts are connections are now made, but I will keep in mind your suggestions

Hi Mart, Nice work guy! I would like to see how the threaded studs are mounted to the post terminals. I've seen that discharge phenomenon happen when I'm charging multiple AAA bateries. Do you have a pdf of that wiring diagram? So you are charging that bank with a combonation of solar and wind? Thats fantastic! You are the man! Are you doing the power inverter thing and harvesting useable AC? Am I asking enough questions? Sorry, too much coffee! Eddie

@Eddiev1985 Hi man! The link is up in the sidebar for the pic. I have not got my wind gen going yet, I don't have it up in the right place just yet. But the solar is working decently. I am trying to stay away from the inverter as much as possible better to go with a straight DC motor or a dc LED. If you don't have to loose energy in the transfer it is a much better day. But.. I am thinking of getting an 24V inverter, my 12V just does not work with 24, or 18V, as I have it setup.

Thanks for sharing! Maybe the copper bars could have their midsections coated with rubberizing dip?

[marthale7]

@Shanjaq Thanks for the tip.. I have not seen rubberizing dip before. I always wondered how they melted plastic to coat thing with....

Great - I like the bending technique and use that on other applications -

Right now until I get the charge controllers hooked-up, etc. - except for the small system I have of being in parallel; that's how I have the panels hooked-up to the batteries with various sizes and lengths of cables - even charging.

And, the same with how the batteries are hooked together as well s to the outlets for even discharging.

Great work and video.

Excellent tip my friend. I can't believe I didn't think of it with all the scrap pipe I have. Keep the videos coming! btw... its "jist of it" not "just". ;)

The copper connectors are fairly easy to find. I'd use solder, not crimp.

It should not be that hard to find, it is a common size used for outdoor cable . Even larger shrink tubing does exist. Here in the Netherlands I can buy it in short lengths of 1 meter.

@marthale7 It is called Plasti Dip.

Plasti Dip is a synthetic protective rubber coating that resists moisture, acids, abrasion and corrosion. You can find videos about Plasti Dip on youtube. :-)

I think copper tubing is indeed a great idea, I like people who share ideas, and it does not matter who came up with the idea.
