I currently have a standard single "starter" battery setup. I want to install a second battery (deep cell) to utilize while beached or anchored half the day while running pumps for toys, radios or cell phone/GPS devices. I think I have my head wrapped around what is needed but I have a few questions. I have come up with two possible setups:
1. Blue Sea Systems (11001) 3 position switch
I think this switch will allow using either "start/bat 1" or "deep/bat 2". You must choose one or the other. The alternator would only charge which ever battery is selected while the motor is running. Run the boat with "start/bat 1" and then switch over to "deep/bat 2" when stationary and using power. Does this sound correct?
2. Blue Sea Systems (9002e) 4 position switch
I think this switch will allow using either "start/bat 1", "deep/bat 2", or "start/bat 1" and "deep/bat 2" simultaneously. You could choose either battery just like in the above situation or you could also choose both batteries. I am assuming if you are running the motor on both batteries, then both batteries would be charged by the alternator. Does this sound correct? Do you have to worry about over voltage (ie both batteries putting out 12 volts) essentially leading to putting out 24 volts? I wouldn't think that would happen unless both batteries were connected together instead of both independently connected to the battery switch.
I think I should need the switch, deep cell battery, battery mount and both pos. and neg. cable. Am I on the right track or is everything wrong. Thanks for any insights.
