Xantrex Truecharge2 Reliability?
Hello all, New member here with a 2015 Rockwood 2306 that we picked up June of 2018. We're upgrading from the terrible group 24 battery to a set of two Trojan T-105 batteries. I'm looking for a sui...

I wanted to close the loop on this as I hate reading threads without endings. Soon afterwards, we decided we'd buy a house and things got busy. Between that and then COVID, we got out just one time this year and the batteries sat without getting hooked up or equalized, though I didw watch the voltage and charge a few times.
We finally left on an 8 night trip. Before we left I did two partial cycles (one around 20 Ah, one almost 50), and fully charged before leaving, checked all SGs (1.275-1.285), and topped up water.
Three nights in the batteries where somewhere around 50% based on voltage measurement about 15 minutes of no load. Load the prior night was the fridge gas solenoid, phone charging, and some background sleeping noise over the camper speakers. Heater probably only ran once or twice all night.
I decided to top off with the generator and set the PowerMax 60 to 15.3 volts unloaded (48 °F right now), hooked it up and the batteries sank all 60 amps since it was voltage limited.
Still have not upgraded any camper wiring yet, I have some 4 AWG connecting the batteries and also going to a battery connector I can tuck in the battery compartment. To charge with the PowerMax I have more 4 AWG from the PowerMax to another battery connector, simply pop the lid, hook up, and plug in. Hopefully I'll get the actual wiring all finished here in a few months, winter should be a good time to work on that.
