Re: Batteries, combination parallel and serial

Thank you Bill and Alexandre.  Bill I will call you on Monday.

In advance of that, in answer to your question, I do not know what batteries were on the boat originally.  I don't know when Amel moved to AGM's but I thought it was in the 54' but probably wrong on that.  This boat is a 2004/ built late 2003.  This boat already had a Balmar voltage regulator on the 175 amp alternator.  It didn't work. I repaired all that, verified that the alternator was functioning properly with the regulator, added a Balmar Alternator temp sensor and plan on a Balmar battery temp sensor during the battery change.  The Balmar regulator is easy to program.  There is a Samlex charger and two Xantrex inverter/chargers that appear to have replaced the function of the Dolphins (still there).  The Xantrex are AGM capable, I don't know about the Samlex 2440 as yet.

The AGM's should be 1/2 inch wider than the current wet cells and just slightly taller, About the same length, looking at that as I decide which battery make is going in and verifying the size.  But yes Alexandre, my compartment is larger than yours, it's like Bill's, with a 12 battery rig.
