What material is that strip? Copper? What is the thickness? What is the width? Where do you buy it? Do you cut it to size? Do you cut it with snips?
If building a large battery for a electric vehicle, I know that we need to know how many Amps will be used to calculate the size of the metal strip used to connect the individual cells. Lets just figure slow electric bicycles and scooters that are mostly just dreams in my mind.
Think mcmaster.com might be expensive? They got a lot of information on copper and different alloys.Electrical Conductivity
Copper alloys are known for their excellent electrical conductivity. Ratings for electrical conductivity use Alloy 101 as the standard. Note: SAE 841 is not rated.
For that i use BCAE1.com car audio website wich have many great java applet to calculate your data.
Yes i used copper. I got from surplus material at work. But i know that some house are made with copper top so try contacting some guy working in the construction domain that are specialized in house top cover.
but you can also get some on ebay as well
to find the number of square mils you need with copper,
Called a roofing supply place. They got 14 inch wide copper flashing. Cost is $12.91 per foot. They call it 16 once. Thickness is .0216 inch. Also called 22 Mils (a Mil is 1/1000 of an inch)
If I cut battery cell connector strips 3/8 inch wide. 3/8 inch is .375 inch or 375 Mils
22 Mil X 375 Mil Copper strip is = 8250 Mils
I HAVE STOPPED UNDERSTANDING WHAT I AM TYPING!!!!!!
As per calculator at http://www.bcae1.com/wire.htm
8250 square mils is 10504 circular mils.
As per chart at http://www.bcae1.com/wire.htm
10 Gauge wire is 10384 mils which is pretty close to what I think my copper strip might be, 10504 mils.
If I am figuring this correctly a .0216 inch X .375 inch copper strip is about equal to a 10 Gauge wire which I think is more then big enough.
IS MY THINKING CORRECT? I AM NOT SO GOOD WITH MATH AND ELECTRICITY.
Marty goes down to the basement to pound on a 10G solid wire with a hammer and anvil to see what size it is when it is all flattened out.
