Hi, I am in the process of upgrading my house batts to Agm super cycle total 940ah. I have twin 135’s in my DeFever 44 trawler. I want to upgrade the alternator on my starboard engine to dedicate to charging the house batts. Looking at the Balmar XT 250, should I add this as a second independent alternator and use twin v belts driving off the crankshaft alone, ( comes with complications and cost around install of brackets and tension bars and limited space) or go the easier route and replace the existing alternator and install a serpentine belt system.

Welcome thoughts and recommendations.

Thanks.

Graham.
