Default Platinum or copper

Hi,

should I buy platinum plated, or copper battery solder bars? Platinum plated are 2x as expensive...

Just get whichever one is cheapest. The resistance of the bar has an extremely small % of the total resistance of the pack.

I agree. Go with whatever is cheaper. Actually silver has the least electrical resistance, next is copper, and gold is the last. You can find silver bars for about the same price as the copper. I would only use platinum if my touring car had spinners too :-)

I think the copper bars are easier to solder on , they seem to transfer heat better.

Are you serious. Why do you think companies use gold and sometimes platinum plating on expensive circit boards.

May have something to to with corrosion but the order of resistance best to worst as follows:

silver
copper
gold
aluminum
tungsten
iron
steel
platinum

As was stated earlier the distance in battery bar is so the resistance is minimal.

Exactly right. It's resistance to corrosion that makes a few materials desireable for this(that's why many people, including the military use gold for their electrical contacts, it seems to have the best balance of low resistance & high corrosion resistance). But for our purposes, copper or silver is just fine, so just go with what's priced best for you.....

Guys, platinum is a HORRIBLE conducter......horrible. You are better off using a piece of wood....

Get the copper ones.....they are not only cheaper, but a superior conducter and much better at dissapating any heat....

Platinum is only used in electrical applications when they need to prevent corrosion and resistance is not an issue....

electricity is electricity and oxidation is oxidation. Neither of which care what the application is. If you are the one who wants the flashlight to work you want clean contacts. Copper is the better conductor when it is clean, however its impossible to keep it oxide free. Gold stays as a noble element unless put under some really hard conditions which is why every one plates contacts with it that they want to keep working for a lot of years.

Gold is much better over the long haul than oxidized copper and copper will oxidize plain and simple. Push current through it when its wet and bad things really start to happen. If you can keep it mostly clean and dry it will work fine
