The Dual Pro PS4AUTO/BOS12V2 is a complete battery management solution combining an advanced 4-bank charger with a 2-bank Battery Optimization System (B.O.S.). This kit includes the PS4 Auto 15A 4-Bank Lithium/AGM Battery Charger and the BOS12V2 12V 2-Bank Battery Optimization System, designed to maximize battery performance and lifespan in marine and other multi-battery applications.
PS4 Auto 4-Bank Charger - AutoProfile Intuitive Charging Technology:
- Automatically detects and charges both Lithium and AGM batteries for optimal performance
- Fully automatic multi-stage charging with independent outputs for each bank
- Startup feature wakes up batteries in low-voltage protection mode
- Quick charge times with algorithms validated by battery manufacturers for 100% charge cycles
- Waterproof construction suitable for fresh and saltwater environments
- ISO 8846 Marine certified and ignition protected (US Coast Guard 33 CFR 183.410)
- FCC 15 Parts A & B interference compliant
- On-board diagnostic codes for troubleshooting
B.O.S. Battery Optimization System - 12V 2-Bank:
The B.O.S. actively shuttles energy between batteries wired in series to maintain equal voltage levels before, during, and after charging. This patented technology prevents the "weak link" problem where batteries become unbalanced, leading to premature failure and reduced performance. The BSAP-24 (Battery Selection and Prediction) algorithm accurately identifies which battery needs additional energy and transfers up to 7.5A to keep the pack balanced.
B.O.S. Features:
- Self-powered operation with less than 1mA sleep mode
- Transfer rate up to 7.5A between batteries
- Compatible with any battery chemistry
- Extends battery life and quadruples run time on the water
- Ideal for trolling motor batteries and multi-battery marine systems
Applications:
Perfect for marine vessels with multiple battery banks, particularly boats using trolling motors and accessories. Also suitable for golf carts, industrial equipment, aerial lifts, solar power systems, electric vehicles, and communications equipment.
Specifications:
- Charger Output: 15A total across 4 independent banks
- B.O.S. Configuration: 12V, 2-bank
- Warranty: 3-Year Limited Warranty
Dual Pro has been the gold standard in professional and sportsman marine battery chargers for over two decades, delivering unmatched reliability, safety, and performance. This complete system eliminates the guesswork from battery maintenance - just plug it in and forget it.
