The new 12 volt EV batteries have been installed. It went better than I expected! Nice surprise. The 8 new batteries shaved off 480 pounds of weight over the 6 volt ones but with their lower 150AH rating there will be a loss in range. Time will tell as I learn and record their performance.
Used the rest of the week to work on models for the new log cabin.
And the final result of the roof truss system mated to the cabin walls looks like this.
Next up? The foundation logs and floor system.
