Hi, I live in Finland and I wish I have came here to ask before ordering. You are doing better than me by coming here before ordering. I have ordered batteries and panels from GWL and I have regretted that a lot. Please take everyones advice and save on batteries by ordering them cheaper from somewhere else. But what I am here to warn you about is do NOT order the solar panels from GWL. They have very poor packaging and they will arrive with visible micro cracks. It took many many many emails and months for them to accept to replace, then they replaced only 2. and guess what this time one of them was completely broken outer glass. Now the 123BMS is something I do not understand why would anyone order? Is there something specific made you want that one?
