Question:

Am trying to figure out which battery charger to use for 2 6v interstate golf cart batteries gc2 in my small travel trailer.changing from 1 12v battery. Saw your answer indicating using the ctek 56191-but the video said was for small 6v batteries. System will be used for short term boondocking.thanks for info

Since your batteries are wired so that the two 6 volt batteries are in series and produce an output of 12 volts the part # 329-GENIUS5 would be a great option. If you want to charge the batteries individually or if you want the total output to remain 6 volts, this charger will still work well for that application.

Some people prefer the 2 batteries in series to a single battery simply because it will still give you 12V power if one battery fails. Also you will want to look into the amp hours because often the 2 batteries wired in series will provide power for a much longer time period. In either situation you will want deep cycle batteries.
