110V Battery Charger Suggestions for Shore Power

I am setting my cargo trailer up as a boondocking/dirtbiking/hunting trailer and am looking for some suggestions on a good shore power battery charger. I am basically following Will's Classic 400 Watt mobile setup but will not initially have much for solar power and will need to keep the batteries charged off of 110V shore power when parked next to the house and a 3500 Watt inverter generator. I just ordered two of the LiTime 12V 100AH TM LiFePo4 batteries (great deal going on them right now) and will have a 2200ish W inverter. I was thinking a 30-40A charger should be sufficient and was looking at the two listed below. I am open to other suggestions as well. I am wanting to mount the charger in the trailer and connect the charger to the batteries and just be able to plug it into shore power and have it start charging.

LiTime 40A Mountable Charger


or

Victron Blue Smart IP-22 30A

https://www.amazon.com/Victron-Ener...6&psc=1&mcid=6e7f2878946d39bf82f88200798b4a74

Seems like I would have to provide cables for the Victron but it does have blue tooth monitoring and the MPPT I will eventually go with will most likely be the Victron 100 -30 or 100-50 depending on how much solar I add.

A little more background on what I plan to run in my trailer off of the 12V battery system initially:
-LED lights
-Small water pump for sink
-12V cooler fridge/freezer
-TV/DVD player thru inverter
-cell phone, radio/comms charging station
-Diesel Heater

Shore power and generator will run a microwave and Keurig coffee maker and the TV/DVD player will be able to be switched to shore power as well.

i like Victron because it's bluetooth adjustable and provides absorption for balancing.

I have bought lfp chargers in the past which stop charging as soon as battery hits 14.6v.

14.2v + absorption time would be more in my comfort zone.

The only other charger i trust is a bench power supply paired with a timer switch.
 
I went with ip67 victron. Totally programmable charging numbers. Different LFP mfgs recommend different charge numbers, I like the ability to set all 4 or 5 voltages.

I looked at the IP67 but it doesn't come in a 30 or 40 amp charge rate unfortunately.
 
No issues with my ip22 12/30.

Down the track you could get a smart battery sense to attach to the batteries, and can setup a ve smart Bluetooth network between the SCC(s), the ip22 and the SBS. The SBS will provide accurate voltage and temperature to the SCC and ip22, you can then enable low temperature charge protection so you don't charge the lfp batteries when it's too cold for them.

I was thinking that as well. If I go with the victron charger, smart shunt, and mppt hopefully they can all be linked and controlled thru the one app. Just go with the entire Victron ecosystem, even though I was initially leaning more towards a 40 amp charger just to be able to top the batteries off a bit faster with the generator.

You can always add a second charger and run them in parallel.
