Steps to change batteries without hurting anything....
Again, tried to search for answer first, no luck. I am ready to install my new lithiums. I want to be safe to not hurt anything so am looking for what to switch, unplug, turn off, etc..prior to making the swap. I am connected to shore power at the moment at a site.

First off I would recommend disconnecting from shore power while you're connecting the battery (or is it batteries?). If it is a single battery it should be as simple as disconnecting the old one and connecting the new, be sure that you connect the correct leads to the right terminals (red positive, black negative). It wouldn't hurt to remove the battery disconnect key before doing this.

When disconnecting the old battery, disconnect the negative terminal first.
When reconnecting the new battery, connect the positive terminal first.
If connecting 2 or more batteries in parallel, first connect positive to positive, negative to negative, then as above.2022 F350 CCSB Lariat Ultimate 7.3

Turn off shore power and unplug the trailer cord from the pedestal. If you have solar and/or an inverter, shut those down also. Turn your battery disconnect off and remove the "key". Next, disconnect the Neg lead from the old battery, then the positive lead. After that, you can install the new battery or batteries in the reverse order......Pos lead on first, then the Neg lead. NOTE.....you may see a small spark when disconnecting the old battery AND when connecting the new battery. The reason is that there are a couple of things in/on the trailer that have access to the 12VDC at all times....line to CO and gas detector and possibly the power going to the radio. It's nothing to worry about though, all of that stuff is extremely small current draw devices.

Not that it would hurt anything, but you may want to check if you have a Lithium Compatible Converter. The lithium's will still work with a convectional one, but will not fully charge to 100%. Others on here are way more knowledgeable than me and can give better understanding as to the benefits of a Lithium capable converter charge and a Lead acid, AGM SLA types of converters. Since your rig is a pretty new model it may be Lithium capable now.

One tip on the solar. Kill the panel power first (disconnect switch if you have that on the panel power line to the controller, or cover. If you don't have a disconnect between the panels and the controller, now would be a good time to add. Then disconnect the solar controller from the battery. Change battery as indicated. Then to reconnect the solar, connect the solar controller first so that is shows connected, then power up the panels. Not following these steps can damage some of the solar controllers out there.

Thank you all for the tips and instructions. Made the swap of batteries yesterday following all the things you all told me. So far, all is good.
