I used 6V batteries in series for my house bank in my last boat. Two reasons: first, my battery locker was not easy to get to and installing or removing a golf cart battery was VERY difficult. It was much easier to do it with two smaller batteries. Second, according to my math I got slightly more run time with the two 6V than the 1 big 12V. The starting batteries were all 12V. I had a nice 30 amp 3-bank charger that would divide it up according to individual battery needs. That did a very nice job of topping off my batteries. I also had a big Generator on board that gave me AC power for the whole boat including microwave and convection oven. The house bank handled all the DC requirements and an inverter just to let us shut off the genset while watching TV.
The two 6V batteries did a very nice job for my application From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Jean-Francois J Rivard via CnC-List Sent: Monday, December 15, 2014 11:18 AM To: cnc-list@cnc-list.com Subject: Stus-List Batteries -- Anyone use 6V's? Just a quick comment on capacity: Don't forget that when the 6v batteries are connected in series to get 12v you get 1/2 the stated Amp capacity as shown on the batteries specs.. The amount of watts they produce is fixed and since the formula is Volts X Amps = Watts.. If you double the volts you get 1/2 the amps.. just sayin' -Francois Rivard 1990 34+ "Take Five" Lake Lanier, Ga
