Upgrade to Lithium FE battery question
I currently have two Renogy AGM batteries, hooked to a Renogy PWM Solar Charge Controller and also charging from the converter. I just scored on a pair of LiTimes LiFEO4 batteries. Plan to instal...

Installed the LiFeO4 batteries today with a Victron MPPT charger, and verified the charger is charging the battery and all 12V appliances work inside the trailer.
My current converter is a WFCO wf-8735-p which charges in bulk mode at 14.4V for up to 4 hours before dropping to absorption mode at 13.6V. The only issue I see with this converter is that it'll not able to top off the battery in one shot. Since I have 200W of solar panels, the solar MPPT charger will top off the battery. So I'm thinking I can save the $ and using the existing converter. Anyone see any issues with that thinking?
thats what I did for over a year, actualy still doing it. I have more solar (325watts) but I don't plug in very often, I just let the solar handle it. for winter storage I just turn off my battery and leave it plugged in, but I am looking at a replacment for the converter section, the wife wants 120V power for a couple things so I am looking at a inverter / converter unit to take that over
Thanks StirCrazy. I live in Colorado and mainly go camping in Colorado and Utah. Sun is very good here. With my old two AGM 100Ah batteries, they're usually topped off by the 200W solar by 10 AM or so.
We also have a Jackery 1000. We use that for coffee maker and microwave when needed and Jackery can usually handle 2 to 3 days of coffee and Microwave without charging. Having a build in inverter in the camper would be more convenient but no need to spend that money now is nicer.
ya, I used to have two 6V 208AH batteries in the camper and was in the same boat, if it was early spring or fall (temps about -5C at night) it might take till noon as I was running the furnace 24/7 haha. riht now I am building a new 304AH LFP to replace the 280AH LFP I put in there last year.. the 280 is going to go into the 5th wheel.
