I put one in last year, in the stock location. I wanted to save the weight from both the batt and the cable kit needed with a relocation. I have not driven the car other than to move it around a little when needed. What I have found is that it cranks the car just fine it just does not have much reserve and can be run down pretty easy. (Kind of expected) Since the car is a toy, I think I will be fine. If I was to DD the car, I think a relocation kit would be the smarter way to go. My next step is going to be a 3g alternator. Hopefully that will top it off faster and help things a little.
