battery problems

[bocagrande]

I have 35 ft express cruiser to witch there are 2 battery banks. Port runs port side engine starter and the bilge pumps and Starboard Runs Starboard starter and all DC accesories to which I have a bank of 12 v deep cell batteries to run the dc system. I am often out for days so I want to get a large bank of 6v and tie them in series to make them 12v and run them parrallel with the starboard battery. No matter what I do I always will need the starter battery on starboard to start the motor and a bank running my accesories. Therefore I will always have a starter battery mixed with a deep cell bank? Will this affect the starting of the strbd motor and or the deep cell battery bank haveing the 2 different kinds of batteries in one bank???

Re: battery problems

i think i would put a selector switch on the system, to isolate the starting battery, then the engine can charge either the starting battery or the house batteries.

i also think i would set up another switch so either engine could start of either starting battery.
