Battery Life

[GPnBIRDIE]

Last week, I began an evening with full charge (Lithium Pro 390 AH).    Running only two small ac Fans along with roof vent at 60% capacity (frig on propane), the batteries went down below 10% over night.   This does not seem appropriate and welcome any feedback.

Running two small ac fans...implies that you had the invertor turned on. Is it possible there were other appliances (water heater, refrigerator, ?) that were on AC that you hadn't intended?  Based on my limited experience, your stated capacity / draw you should expect a week or so. Do you have other previous instances of running on strictly battery?

By "ac fans" do  you mean your air conditioner?  If so, that could explain the substantial draw down on your batteries.  Our Truma AC pulls about 1100 watts when the compressor is running.

If you have the Lithionics app on your phone you can see how much current you are drawing.

If you mean you ran the inverter, and just ran two small 110 fans, i think you may  have an issue. 

Please complete your signature. 

Many lithium require  full charge within a period of time to properly register  "full charge" status.

Even our Bluesky, with agm batteries,  requires hitting 100 per cent charge to show proper readings after a disconnect. Kind of a "reset" situation. 

You may also have a wiring issue.

Being a 2022 model, a quick glance at their Victron monitor would give them a ton of real time information. 
 

I’m not a fan of Bluetooth Apps to get info about my system’s status. Too much trouble to find your phone, find the app, get it up and running……

I can't help with finding the phone as it is a problem I often have myself. Finding the app is simplified for me because I organize all my apps in folders and then organize the folders alphabetically. This folder is named "Oliver" and it contains Lithionics, Xantrex, LevelMate, and WBA Check. In the folder I organize based on frequency of usage, although with only four apps in this one that's hardly important.

Oh, I do all that the same way you're describing; apps in groups, groups placed where they are easily found. It's still easier for me to glance at a dedicated read-out mounted in the trailer than to jump through all those hoops.
