Charging a Battery Bank
I am planning on upgrading my batteries to 4 6v batteries wired in series and parallel to have a 12v system with plenty of Amp Hours. There is a ton of information on how to wire things up but nothing...
Forum Discussion
In the OP's previous thread he expressed a desire to upgrade to FOUR 6 volt GC-2 batteries and a genset for recharging them because he had booked a 4 night dry camping trip. I asked in that thread and now again in this thread - why are FOUR GC-2s necessary when TWO should easily get him through at least a day or two of pretty good use and he has a genset available for recharging those batteries each day? :h
I can understand Roy wanting more reserve capacity since he's a HAM radio operator but for the average user with a genset wouldn't just two GC-2s suffice? If I understand BFL13 correctly four drawn down GC-2s will accept a greater rate of charge than will two but only if the charger and genset being used are capable of supplying this higher rate of charge. IIRC we still don't know what converter/charger OR genset the OP intends to use for this purpose but unless both are capable of supplying these elevated charge levels would charging four GC-2s at a lower rate not take a longer than charging just two, meaning longer genset run time? Just asking - unless the OP has a specific need for so much reserve capacity he's not telling us about why would two GC-2s not be sufficient for the OP, and indeed many others who may camp similarly? :h I'm just kinda wondering if this is not a case of thinking "more is better" without giving due consideration to the other half of the problem, which is how to efficiently recharge a battery bank consisting of four GC-2s. :@
