Dual Pro PS2AUTO/BOS12V2 2-Bank Auto Battery Charger with B.O.S. System

The Dual Pro PS2AUTO/BOS12V2 is a complete battery management solution combining a 2-bank automatic charger with an advanced Battery Optimization System. This professional-grade kit includes the PS2 Auto 15A charger with AutoProfile technology and the BOS12V2 battery balancing system, designed to maximize battery performance and longevity in marine and other demanding applications.

AutoProfile Intuitive Charging Technology:

The PS2 Auto charger automatically detects whether batteries are Lithium or AGM chemistry and applies the optimal charging profile for each. This intelligent system delivers a complete 100% charge using algorithms validated by battery manufacturers, with the fastest charge times in its class. The startup feature can wake batteries that have entered low-voltage protection mode, while the auto-return feature resumes charging after interruptions.

B.O.S. Battery Optimization System:

The included BOS12V2 module actively shuttles energy between batteries wired in series to maintain equal voltage across the pack. Using a sophisticated BSAP-24 algorithm, the system predicts which battery needs additional energy and transfers up to 7.5A to balance the pack before, during, and after charging. This prevents the common problem where battery packs fail prematurely due to imbalance, extending battery life and quadrupling run time on the water.

Key Features:

• Fully automatic 2-bank charging with independent outputs
• Compatible with both Lithium and AGM battery chemistries
• Waterproof construction suitable for fresh and saltwater environments
• Self-powered B.O.S. system with less than 1mA sleep mode
• Multi-stage charging with on-board diagnostic codes
• ISO 8846 Marine compliant and ignition protected per US Coast Guard standards
• FCC 15 Parts A & B interference compliant
• 3-year manufacturer warranty

Applications:

Ideal for marine vessels with trolling motor and cranking battery setups, golf carts, industrial equipment, aerial lifts, solar power systems, electric vehicles, and any application where batteries are configured in series.

This plug-and-forget solution from Dual Pro delivers unbeatable performance, reliability, and safety, backed by over two decades of marine industry leadership.
