The 18650 I threw on there last night seems like it gave it's all within the first couple hours. Voltage at .04 and no further progress on transferring copper. Time for a swap.

I plopped the buck converter back on the tree to make some progress with the voltage at 2.5 and .25 amps making it through.

At this rate I hope to get results from the copper build up and hopefully move on to the art and electronics portion of the project
