I did a little more work on the Metro today.
I have always wanted a higher system voltage, but I am pretty maxed out in terms of what I can fit in the back seat battery box.
Since I also want to keep my trunk space (which had also been experimentally filled with the Hybrid System.) that means the only place to add more batteries is under the hood.
Because I have been using Group 31 batteries, they are just a little TOO long to fit in the "radiator rack" going the long direction, leaving me only ONE battery in front.
Today, I removed that one battery, and started experimenting with FOUR shorter batteries to figure out how I would fit them in. It's trickier than one first might think... The way the headlight trim curves around, the center support is off-center, and other odd things made it challenging.
Here's an image with the nose off, trying to squeeze all those batteries in there.
Working around the headlights was difficult. The light trim sticks out way too far.
After much grunt and shoving batteries around, I think I have arranged them in such a way that all four will fit.
I packed up the car for the eventing, and plan on building and installing battery tie-downs and cables tomorrow.
