Product Overview

Dual Pro SS4 Auto 40A Battery Charger with B.O.S. System

This innovative kit features Dual Pros Battery Optimization System (B.O.S.) paired with the SS4 Auto 40A Battery Charger, designed for optimal charging of multiple battery types.

Battery Optimization System (B.O.S.)

The B.O.S. effectively manages energy distribution among batteries, ensuring they remain balanced to maximize performance and longevity. This system addresses the common issue of battery packs becoming unbalanced over time, which can lead to premature failures.

B.O.S. actively transfers energy as required between batteries wired in series, ensuring equal voltage during charging cycles. This technology enhances the operational efficiency and run time of your batteries, especially in demanding settings like marine applications.

Key Benefits:

  • Maintains balance in battery packs for prolonged performance.
  • Utilizes an advanced algorithm (BSAP-24) for energy distribution.
  • Compatible with various applications including marine, golf, and solar.

SS4 Auto 40A Charger Features:

This charger is engineered to automatically detect and charge Lithium or AGM batteries, providing the quickest charge times and optimal battery health.

  • Fully automatic operation ensuring a hassle-free user experience.
  • Designed with waterproof capabilities for both land and marine use.
  • Independent outputs allow simultaneous charging of multiple batteries.
  • Compliant with marine safety standards and interference regulations.
  • Backed by a comprehensive 3-Year Warranty.
