Dual Pro PS4 Auto Charger with Two-Bank B.O.S.

A four-bank charger and a two-bank balancing module do different work, even when supplied as one package. This Dual Pro kit pairs the PS4 Auto lithium/AGM battery charger with the two-bank B.O.S. optimizer. The charger provides independent battery charging while the B.O.S. handles energy transfer between the series-connected batteries it is assigned to balance. That distinction helps when planning a trolling motor and accessory battery installation.

The PS4 Auto uses battery-chemistry recognition to select charging behavior for supported lithium or AGM batteries. Its automatic multistage operation includes diagnostics and the specified lithium startup feature. The B.O.S. uses the BSAP-24 balancing algorithm and can move energy between batteries as needed. It is designed for a two-bank series arrangement, even though the charger has four outputs.

Waterproof marine construction and ignition protection are listed for the charger. The combination may suit a boat needing multiple independent charging leads and dedicated balancing for one series pack. Component placement and battery wiring should follow the respective installation requirements. Explore other marine charging systems for alternative bank layouts.
