The boat I purchased this fall has dual batteries run through a standard perko switch. I have a few questions regarding charging the batteries during the winter (without disconnecting the battery cables).
Assuming the perko switch is properly wired...
...can I charge each battery individually when the perko switch is turned to "off"?
...can I charge both batteries at the same time with the perko switch turned to "all"?
The logical answer to both questions seems to be "yes", but I want to make sure I'm not missing something. My gut also tells me that even if I can charge them at the same time, it would be better to charge them individually.
Thanks in advance!
