battery relocation question

Subject: battery relocation question

I hate to say this Brian but aluminum DOES NOT conduct better than copper. 
This was taught to me by MANY people including electricians. It may be 
lighter but I have heard that the weight loss is no where near worht the 
conductivity loss.



Peace Out,
