Parking Mode and Battery

Parking Mode and Battery

I just received my AIO-5 Play and am about to wire things up - but I have one question:

I know the parking mode/alarm functionality requires the constant power to the battery terminal with normal operating power coming from the ACC wire to an ignition/accessory source...

My concern is even though the unit has low-voltage detection to prevent fully draining the battery, I have a lithium battery in my bike, which I'm not sure if it works the same way (I think LifePO batteries will not drop below the 12v until they're pretty much dead - although I could be wrong).

With that, I thought of two possible alternative ways to connect things:
  1.  Put an inline switch on the red wire to easily cut power if the bike is going to be sitting for a while, or if there's no need for the parking mode/alarm.
  2. Connect both the constant (red) and ACC (yellow) to an accessory/ignition wire on the bike and simply not use the parking mode on the AIO-5.
My question is, are either/both of these viable options?

Or am I just being paranoid about the low-voltage?  I don't really want to leave myself stranded (can't really boost lithium), and if a LifePO lithium battery goes completely dead, it pretty much needs to be replaced.

** Note:  I do not have the cameras, so the concern is just the vibration alarm.
