Sure. Understood. That's why we are all here. I'm just pointing out that it is premature to conclude the driver is at fault. I actually have six data points that are contraindicative of a driver issue draining the battery.
I may be able to come up with a test case where there is zero motor activity, and I can see how a fully charged battery drains in that scenario. Related: See my post in this thread showing the guts of the shade .
