Two Bank or Three Bank Battery Charger?

Question:

Hi Jeff, I am upgrading my battery bank from a two battery bank to a three bank system. One dedicated starting bank for each engine and a third dedicated house bank (two parallel group 27s). I am also adding a BEP Battery Distribution cluster with twin VSR(s).

Can I keep the original two bank battery charger and run the charger through the new VSR(s) or should I upgrade to a three bank charger and connect the new charger directly to the batteries?  Thank you. - Bryan

Answer:

I would definitely recommend upgrading to a three bank battery charger for safe and even charging.  Xantrex makes a great three bank charger in the True charge 2 - https://www.pysystems.ca/products/xantrex-truecharge2-40a-battery-charger/
