Ampertime replied it seems they have good customer support, hopefully they will give me a quote, is the low temp cut off important ? this is the temperature while charging so its day time maybe 6am not the lowest night time temp. right?
I found locally some batteries 12v 100ah of a brand called Genesis, the vendor is selling them for PV but on the web site https://www.enersys.com/en-gb/products/batteries/genesis/genesis-td/ they dont seem to be classes like that, does anyone have some info on them?
That 24W is a mistake it should be 7W. The Multiplus C 24/800/16-16 which I think you are reffering to it comes with a charger but it has a price of 900eur, at the moment out of my budget, however I had only a superficial look for chargers, so far the ideas I got is that for acid batteries it...
But lets say I want to buy just one 12V battery now and one later, if they need to be as close as possible then I cannot do it in series ot I could but I will lose the diff. Of the used to the new one. So maybe I do that in parallel?
