Dual Pro PS4 4 Bank Battery Charger w/3 Bank B.O.S.

The PS4 4 Bank Battery Charger with 3 Bank B.O.S. is an advanced charging solution designed specifically for marine and boating applications. Combining Dual Pro’s Battery Optimization System (B.O.S.) with a robust Professional Series Battery Charger, this kit ensures your boat’s battery pack remains balanced, extends battery life, and provides reliable power when you need it most.

B.O.S. (Battery Optimization System) - 12V - 3-Bank

The Battery Optimization System (B.O.S.) actively manages and balances the energy between your batteries, ensuring each one operates at optimal performance. This system prevents the common issue of battery imbalance, which can lead to reduced battery life and performance.

How B.O.S. Works

Batteries in a pack can become out of balance, making the entire system only as strong as its weakest link. In marine settings, this issue is exacerbated when the trolling motor battery is used alongside the cranking battery. B.O.S. intelligently shuttles energy between batteries wired in series, maintaining equal voltage before, during, and after charging. This results in balanced packs, maximum performance, and quadruple run time on the water.

Traditional systems often accept premature battery failure due to imbalance as the norm. B.O.S. revolutionizes this with its BSAP-24 algorithm, which precisely predicts and selects batteries needing additional energy to match the others in the pack. This technology not only extends the life of each battery but also enhances overall run times.

Features of B.O.S.

• Available in 6V, 8V, and 12V configurations
• Supports up to six batteries in a series
• Battery Selection and Prediction (BSAP-24) algorithm
• Less than 1mA sleep mode
