Dual Pro PS2 Charger with Two-Bank B.O.S. System

This Dual Pro package brings together a Professional Series PS2 charger and a two-bank B.O.S. battery optimizer. The PS2 supplies 30 amps total through two independent 15-amp charging outputs. The separate optimization component is intended for batteries connected in series that may not remain equally charged. Combining them addresses charging and balancing as two distinct jobs in the same onboard power system.

The PS2 includes automatic multistage charging, battery maintenance and onboard diagnostics. Wet-cell and AGM charging are documented for the Professional Series charger. The B.O.S. module transfers energy between connected batteries using the maker's selection algorithm. Its low-draw sleep mode and self-powered operation let it remain integrated into the battery arrangement.

Marine installations benefit from the charger's waterproof construction and stated ignition protection. The B.O.S. component is a balancing system, not an additional battery charger bank. Confirm both components are suitable for the battery chemistry and series wiring planned for the boat. Browse our onboard marine chargers for other combinations.
