Re: What to do with LiFePO4 batteries when the boat is layed up?

On BeBe I have a Victron Venus GX which acts as a hub between all ov my Victron devices. It can also monitor and control other devices through CAN Bus connections. But with respect to this thread, it connects to Victron's web server via WiFi.
You can potentially connect it directly to a marina wifi or via your ships network. In my case we purchased a stand alone wifi hotspot called SkyRoam, from Solaris. It works globally (130+ countries) via cellular networks (I don't know if it is sold everywhere). They have very flexible data packages. The data is not necessarily cheap but we loaded up 5 gig before we left for the summer and have barely used 100 meg while away.
Once connected I can see the Victron GX (see attached screenshot) from anywhere on my phone app, AND I can also turn my Victron MultiPlus charger/inverter on and off remotely. I have a trickle charger on my Inverter circuit that is connected to my starter battery, a month ago I turned on the inverter and monitored the current flow as the I topped off the start battery for a few hours)
I maintain my LiFePo house bank via solar, but have set the float back to about 26.6v (less than 70% SOC).
The screen shot taken earlier this am shows my over night voltage and some charge starting to come in from the solar.
I can drill in and see consumption, solar generation and trends over time.
It gives me great peace of mind to be able to click on an app and see a few critical things going on the boat while away.

We left the boat for 4 months earlier this year and while I have a Victron based system, I think you can achieve the same on MV:
