Just went to take the bike out for the first time in awhile. Checked the battery with a multimeter on the way out the door only to find my battery dead 45V. It was charged, fully about two weeks ago. I did unintentionally leave it hooked to the benchtop power supply. I guess that even with both the battery and power supply being off it somehow caused the discharge. It's trying to do a fast charge now at 5 amps. I either need to leave here by two or wait until next week or the next break in the weather...
