You said that these batteries are cheaper but I google it and it seems are much expensive. Can you provide me with a link from where you bought yours?

They are compared to Lead Acid. I guess is what I was saying.
When you compare the price of batteries  you calculate the cost per energy stored during lifetime of the battery.
So you divide the price of the battery at the (number of cycles x depth of discharge x capacity x charge discharge efficiency) so you get price /KWh stored the best I have is the A123 System the 20Ah cells they are about 20cent/kWh stored during lifetime still more expensive than grid energy in most parts of the world including Romania but not by much.
Mersi de sbuscriere.

Am avut nevoie de facut curatenie dupa ce am terminat de construit casa si am cautat pe net mai multe informatii si n-am stiu ce sa aleg din multitudinea de site-uri, noroc ca un vecin mi-a zis de acest site si la recomandarea lui m-am hotarat sa colaborez cu aceasta firma. Pretul a fost bun si totul s-a desfasurat rapid.
