At the risk of doing math in public...I'm not sure I'm understanding how the parking mode draw is actually a problem.
The K2 draws 40 mA in parking mode right? Let's say the bike gets parked for 13 hours while I get home from work, do evening stuff, sleep, get up, then get on the bike to go back to work.
13 hours * 40 mA = 520 mAh., or 0.52 Ah.
My Vstrom uses a 14 Ah-rated battery. I've had it for around a year and a half, so let's say it's now got a maximum capacity closer to 12 Ah (which should be conservative right?).
I'm pretty sure it'll still crank when down to 11.48 Ah.
Maybe not? Are some/all of my assumptions unreasonable?
