Here's a quick rundown.
- Ran power from the main battery pack to the DC to DC converters
- Hooked the DC to DC converters up to the auxiliary battery
- Tested the output of the converters while car is off and while it's running
- Installed all the inline fuses for the Zilla controller and Link 10 meter
- Connected the reverse lights to the reverse switch in the transmission
- Went through the menus and set up the Link 10 meter
- Went through the Zilla's configuration menu and set that up
- Cut and refit all the carpet and plastic parts for the trunk
- Checked the air pressure on all the tires, set them all to 40 PSI
- Charged the batteries completely and set up the charger
To keep them safe, and extend their lives, I've opted for a target charge of 3.5 Volts per battery; times 48 batteries equals 168 Volts. I didn't come up with this value on my own, I learned a great deal from Jack Rickard and his web site: EVTV.ME . Jack has done a hell of a job exploring the limits of these batteries, posting the results and explaining what he's learned from doing so.
So with the target of 168 Volts, I plugged in the car and started pushing some current to the batteries. The charger can read the pack voltage, and it has a potentiometer that allows you to set the voltage you're pushing. Once the pack reaches the voltage you want, you turn the potentiometer down until a light comes on. That indicates the target voltage has been reached and the charger goes into a timer mode and backs down the current until it switches off.
The whole endeavor took 5 hours, with me checking voltage every 5 minutes to be sure I didn't miss the target. It was a long day, but I got the charger set, and I only had to do it once.
I ordered a replacement for the stock tachometer. I fiddled with it for an hour and couldn't make it move at all. It's too bad, I really wanted the stock look. But I found a place on line that makes custom ones, with what ever color numbers printed that you want, what ever background light, a number of fonts to choose from etc. And it was very reasonable at $120. The bad news is 7 days before it ships.
