Hi, this may be obvious, but I've got to ask...
I have a 12v battery bank consisting of 4x 6V, 200AH, AGM batteries.
I have 2x2 connected in series to form 12v, then these blocks of two are connected in parallel - giving a 12v system.
My question is: What is the total AH size of my battery bank. Is it simply the combined total of all batteries? ie 4x200AH=800AH
Or is it the size of only those in parallel? ie 2x200AH-400AH?
