I am going to be given a new Optima red top. Currently I have a two battery bank system for the whole boat with a Perko switch. Can I parallel the current Deka marine batteries (non AGM) and use the Red Top as a starting only battery? I don't see a reason why it wont work but before I do it I want to double check. Can I run the Perko switch on ALL while the engine is on charging both AGM and Wet Cell batteries without any issues? This winter I am likely going to add a Blue Sea Isolator so that I don't have to change the Perko switch whenever we run the stereo with engine off, will this be a problem as well using an isolator. The Deka batteries are old and this winter I will probably be replacing those as well but I may get cheap Marine batteries from Walmart, Costco, or Autozone... Not sure I will get AGM Marine batteries for stereo set up because I have read that many of you get the cheap batteries and just replace every 2-3 years.
