who was talking about recharing them when cold, he said he would have to take them out for long periods when he wasnt there. no, you simply need to turn them off and let them sit. sitting in the cold over the winter wont hurt them and in the spring when you go back to your seasonal site you just turn the switch back on.
maybe we need some claification on what he ment by that statment but I took it as removing the batteries for the off season when they wernt using it.

First of all this is now a moot point. We already own a set of Soneil 260 ah batteries, but.....
We have a seasonal campsite .8 mile from our home. In the fall I store the camper near the entrance where the campground owner blows snow, so we can take off in Jan/Feb to head south. In that location we are not allowed to use the campground electricity. We use solar to keep the batteries charged and sometimes use the camper for overflow guests at our home. I want to immediately use the batteries no matter how cold it is outside. Azmuth had no problems with this scenario, since cold weather use is one of SiO2's attributes. Not only do I want to be able to use the batteries in cold weather, I want to be able to charge them without having to run the furnace. When I talked to Battleborn they weren't too keen about either idea.

so by looking at your senario (I know its a moot point that you have already bought them, that wasnt clear, ( it looked like you were looking for opinions) anyways I was only stating that LFP would have worked just greatfor you if I am understanding your use. when you disconect them they only loase about 1% of charge per month so when you move it to the spot you keep it it would be pretty much how you left it with out solar. and if you go down south to camp in the winter your obvioulsy going some where warmer. you can use LFP (discharge) down to -20 degrees C. charge a a little below 0 but not much. this is battery temp not outside temp.
but since you got SiO2 then be happy with them, they are a definat step up from normal lead asid batteries and even AGM. I am just tired of people posting thengs that are wrong about LFP and others seing that and thinking they cant use them. aside from Pianotuna I have only seen maybe 1 other person that uses the batteries in an extream way but that other person does use LFP, he just has them inside the heated space, and I understand Piano's reluctance to do that as he is in a motor home with lots of batteries and to do a change in type, although it would save hime a bunch of space and give him even more capacity the other costs of figuring out how to keep them warm and or pre warm them for his aplication is to much, so eventualy he will be an owner of SiO2 batteries also. I just hate seeing people spend more money than they have to , I would make a horabile company owner haha
