My 2 6v batteries are about 110 a/h each, so I have about 220 a/h capacity. My old 12v batteries only gave me about 150 a/h, total. The real off-gridders use 2v batteries, and can last for days and days without charging.

Lyle, two 110 ah 6v battery when place in series are a 12V battery with 110 ah.

I believe you maybe have 220 or 225 ah 6Vers that you series to produce 12V. Parallel increase ah's, series increase voltage, just so everyone understands!
