I started thinking about my charger, nothing wrong with it however I am a little concerned about its rated output and not being as smart as I would like. The unit is a Charles 5000 series 60a which is connected to 3 banks.

My issue is although it is rated at 60a, most of this is sitting idle as it really is the house bank that needs all the juice quickly and if I understand this correctly that give me only 20a on the house. On top of this if I read the specs on the link below it only bulk charges for 4 hours as this stage is on a timer which is a rather poor design IMHO but at the time was probably the way it was done. Charles got out of chargers several years back by the way. http://www.charlesindustries.com/marine ... 5B1%5D.pdf

I have been looking at a Pronautic 50a. Seems like they are well liked. The biggest plus is they will transfer up to 100% of their output to a single bank if required which means that very low house bank will get 50a bulk charge as opposed to 20a with the old Charles unit even though it had a higher overall rating. I am quite sure a decade plus of newer tech will make a difference in many aspects of the newer chargers and promote longer battery life with proper charging curves and automatic equalization. http://www.promariner.com/en/news/pronauticp

Here is a link to the model I am considering. http://www.promariner.com/en/63150

Looking for input of others regarding old tech vs new tech chargers, chargers types and is it worth the upgrade. Will set me back around $350 US if I go through with this.
