Need to replace the original 2 bank 30 amp charger on my 2005 282 Sailfish - twin 250 Yamaha outboards (3 batteries - 2 starting and 1 house loads - with dual battery selector switches) and looking at the Guest 2731A 10/10/10 amp 3 bank charger. Assuming I'd configure with one bank on each battery instead of the current set up of Bank 1 (Starboard engine starting paralleled with house load battery) and Bank 2 with Port engine starting battery. Can you configure with a individual charger bank to each battery and still maintain a 2 battery switch configuration for engine / battery alignment? Someone at a local dealer suggested to go with a Guest 5/5/5 3-bank model and use a 15-amp extension cord for AC input instead of powering through the 30-amp shore power connection. I was thinking a 10/10/10 amp for 3 - group 27 batteries would be better for charging and I really wanted to keep the 30 amp shore power / thru on-board AC panel battery charger switch instead of a separate 15 amp extension cord for charger. Anyone with experience making this original 2-bank charger swap to a 3-bank charger?
