Seeking Charger Replacement Recommendations

I have an Ericson 30+ with a Thoosa 9K motor.  My only charging is done with shore power.  My charger, a QuadPro has died. Well, half-died It's 4 12V chargers in a package, and 2 out of 4 are dead.  What do people here like for replacement?  Another QuadPro?  Something that instead would charge the whole 48 bank instead of charging each 12V battery separately?  (Battery is made up of four 4D 12v 198…See More

Proper Propeller Propulsion

I am in the middle of converting my 33' Seawind Catamaran with twin inboard electric motors. This boat had twin outboards 9.9HP Honda motors that were located in a inward position between the hulls that made it impossible to work on unless you removed the engines (hours to remove or install).  So I removed those gas outboards for the last time and bought two 35 HP rated, brushless 3 phase motors with Curtis controllers to run on 48Volt Lithium batteries from a Chevy Volt (2 for each).  I am…See More
