Cary,
Here are some more considerations as you enjoy your adventure. When you connect 2 deep cycle 6 volt batteries in series you will double the voltage to 12 volts but not the amperage rating. So your system with 4 -6 volt deep cycle batteries will be 2- 12volt batteries in parallel with 420 to 440 amp hour rating. A fully charged 12volt system resting will yield 12.8 volts. These batteries should never be discharged below 50% of their capacity which is 12.3 volts. Failure to do so will damage their life span. Another consideration is Peukerts law when discharging batteries. When discharging lead-acid batteries the rule is between 25 and 30% loss of capacity dependent on rate of discharge. If you operate within these parameters the batteries will last 4 to 5 years if you do the maintenance. Make sure you cover any solar panels when you disconnect the batteries. Failure to do so may damage the solar voltage regulator. Hope this helps, and welcome to the forum. Fred
