I would prefer to call it "Sailnet pragmatism" instead of sarcasm. After the SS thread you gotta agree it's important to clear up the basic rules
Sorry if you took my comments as aimed at you.
With respect to the Northstars, I don't know yet if they will be all I had hoped for them. From a purely anecdotal perspective after 10 months of experience with them, they appear to be performing well.
I am not equipped to perform the level of monitoring, measurement and reporting that some on the forum would like to see. I am not an electrical engineer and make no claims to such knowledge.
I am able to read, research, inquire about options and then think through a plan that makes sense for me and my boat using the data gathered from such activites. I am also not risk averse when it comes to small investments such as this but many are.
I went with the Northstar AGMs for the following basic reasons, (1) Form Factor/AH Capacity/mounting flexibility, which allowed me to increase my house capacity by about 25% in the same battery space (2) Minimal Service reqs as my batteries are located in an area not easily accessed for service (3) low self discharge rate typical from AGMs, and (4) higher rate of charge acceptance available with AGMs as I currently only have an engine driven alternator for charging when away from shore power.
Of course many of these factors are not unique to the Northstars and are more generally attributable to the AGM technology. The form factor did appear to be unique to them , at least last year when I made my purchase.
I have not formed an ideal configuration for Whampoa yet. I am considering further capacity expansions but at the moment I am working to understand what might be necessary to double the house capacity and then how I would keep it charged etc. For now my power needs are met but as we look to extend our time off of shorepower I am sure I will want to make some upgrades.
