Battery Discharge on Shore Power

I have 2 200ah Lifeblue lithium batteries. When on shore power the BMS records a cycle on each battery about every 2 weeks. The rep said they cycle when 80% power is drawn from the batteries.My Victron 712 and the BMS app never show the batteries below 97% on shore power. What would be the constant draw even if its as small as 2 amps on shore power. I have-not seen anything online addressing this.

Well as discussed previously there are potentially a few items on the battery.
1. The slides are often direct as there is some memory there
2. The step is direct for safety reasons in the event your take off with them out.
3. Some things that have clocks and need a constant hot.\

Another often forgotten is the CO/lp sensor. It is direct attached.
If propane on board then the kill solenoid is also powered on per design.

Just a couple more of "parasitic" draws
