I have a camping boat with 2 x 100Ah AGM batteries and a switch panel for 1, 2 or 1&2. Starter battery (1) and battery (2) for the fridge, Ipads etc. I want to be able to charge fairly quick when there is access to shore power, use solar when in nature and to keep batteries full when at harbour (no power there).
What charger is best for my setup? Thinking of these...
Blue Smart IP67 12V 17A
Blue Smart Ip22 30a/3
Blue Smart Ip65 25a
For solar this is my thinking. Connect this to both battery 1&2?
Solar panel 100W with regulator Smartsolar Mppt 75/15
In the future I’m considering changing battery (2) for a lithium if needed.
Im new here so any recommendations is greatly appreciated.
