ADVISE PLEASE..Replacing on-board battery charger--any advise?

NOCO Genius 2 Bank or the MK 220D The Genius is lighter, cheaper and IMO a better charger. I would stick with 10A minimum.

If there is a chance you might go to a 24V TM in the future, get a 3-bank charger and tape up the leads from the extra bank.

I agree with going with a 3 bank. They use to tell you to terminate spare leads (double up on 1 battery). If you didn't the charger would always be in alarm because it didn't see a battery at the end of the taped up leads. I don't know if that is still true or not as I haven't kept up with it.

Dual Pro would be my first choice. I have had them in three boats and also installed them in equipment that belongs to our racing club. Positive experiences all the way. Sales staff is very helpful and like a previous poster mentioned " Made in the USA ". Sometimes they have factory refurbished units with warranty at reduced prices.
