   My solar system now is made up of two 100ah Lifepo4 batteries, two 230 watt solar panels, along with all the needed supporting equip. My batteries are Renogy bluetooth self warming. I do not keep the camper plugged in when stored at home, and my batteries stay topped off, even with the 12v fridge running. I will NOT be running anything in the winter time, except the normal parasitic drain of car mon detect etc. Should the batteries be removed? I'm in new england and 20 degree days are plentiful, and sub zero temps in january - february.

	LFP batteries are theoretically OK to use down to -4F, however there are issues charging them in low temps. Whatever you're using to charge them should account for the low temp, and reduce the charge current accordingly.

	You did not say specifically which battery model you purchased. I looked up and if it is the RBT12100LFP-BT-US, then you are good to go. The batteries will turn themselves off if the temperature gets too low. If you have solar connected, then the batteries will warm themselves until they get warm enough to operate. Pretty nifty. As long as you have sunlight, it will work. However, if you cover the trailer or have extended cloudy weather, then it is likely best to disconnect the batteries.I mention the specific model, because not all the models have the self-heating function.

	I am assuming you are speaking of the rp195? For the life of me I don't know where you could cram that much solar on a 195 I have a similar setup on my current camper; a littler more solar and a little more battery capacity, but in theory it works the same. Like StephenH said, if your batteries have a thermal shut-off, you will be fine. If they do not have a thermal shut-off, follow GlueGuy's advice.
