Disconnect SmartShunt when disconnecting battery?

I have a 100ah lithium battery in my RV. I disconnect it when storing or when I'm connected to shore power for more than a week.

While my battery is disconnected, should I disconnect my SmartShunt from the battery? And how much power does the SmartShunt draw when it's passive (not connected to a device via Bluetooth)?

At the "< 1 ma?" spec, power isn't significant enough to disconnect it from the battery (100,000 hours). Plus, with the shunt disconnected, it looses track of SOC and would need the batteries to be fully charged to provide that information again. I'd leave it connected.
