Long term power off - settings saved?

Hi, my motorhome is going into storage for a few months - (no solar, no shore power). I have Victron LiFePo4 batteries on board with a Multiplus, VE.Bus BMS, Cerbo GX, smartshunt, Lynx Power In, Orion.

I had planned on the following

0. Turning the multi off at the DMC panel

1. flipping the breakers (off) for the charge input (solar and orion), and load output.

2. Pulling the main fuses from the Lynx so that the batteries are isolated from all load/charge

Anything else I've forgotten?

Will my settings on my MultiPlus and Cerbo GX be saved if they are without power for several months?

/David

Answering my own question here … in addition to the above, I removed the +ve connection to the smartshunt, removed the Cerbo power plug, removed the Allow-to-charge and Allow-to-discharge wires from the VE.Bus BMS.

The batteries did not lose any charge.

There was a recent post from the MD, saying LiFePo would not self-discharge during winter storage.

Didn't cover settings, but I expect they won't disappear.
