Product Overview

Dual Pro Battery Optimization System 12v 2 Battery in Series 24v System

Model: BOS12V2
  • Approved for use with Wet Cell, AGM and Lithium Ion batteries
  • Designed for 12V batteries
  • Designed for use in fresh and saltwater
  • BSAP-24 Battery Selection and Prediction Algorithm on board
  • Less than 1mA sleep mode
  • Self-powered

Premature battery failure due to an unbalanced pack has unfortunately been accepted as the 'norm' for decades. The B.O.S. breaks through those accepted "norms" and solves the problem with a BSAP-24 algorithm that can accurately predict and select the battery that needs additional energy to match the other batteries within the pack. This simultaneously and successfully extends the life of each battery in the pack. The net result is substantially increased run times and extended battery life.

B.O.S. is compatible with PROViewTM Link battery monitoring software that enables you to monitor your battery status via your smart phone or tablet. The PROViewTM Link App is available to download for free at the Apple and Google Play stores. Learn more about the capabilities of PROViewTM Link at the Energy Management page.

The Battery Optimization System is compatible with most Lithium* batteries.

*Always verify with PCS before using with Lithium batteries.

*Use PROVIewTM Link to configure B.O.S. for use with approved lithium batteries.


Expert Overview

The Pro Charging Systems Dual Pro Battery Optimization System (BOS12V2) is designed for IT environments utilizing 24V systems composed of two 12V batteries wired in series. This system addresses premature battery failure and reduced run times caused by unbalanced battery packs. It actively shuttles energy between individual batteries to maintain equal voltage, ensuring each battery in the pack performs optimally. The integrated BSAP-24 Battery Selection and Prediction Algorithm identifies and rebalances batteries requiring additional energy. This process extends the operational life of each battery and can increase overall run times. The BOS12V2 is compatible with wet cell, AGM, and Lithium Ion battery types, and features a less than 1mA sleep mode for efficiency. It is also compatible with PROView Link battery monitoring software for remote status checks.

Technical Specifications

B.O.S. Battery Optimization System - 12V - 2-Bank

B.O.S. actively shuttles energy between batteries to keep “the pack” balanced, increasing battery strength and longevity.

Batteries in a pack will become “out of balance” and the pack is only as good as its “weakest link”. In watercraft applications, this is further compounded when the trolling motor battery is used for peripherals and/or to assist the cranking battery.

B.O.S. actively shuttles energy as needed between batteries wired in series to ensure equal voltage before, during and after charging.

B.O.S. keeps packs balanced, enabling maximum performance, and quadruples run time on the water.

Premature battery failure due to an unbalanced pack has been, unfortunately, accepted as the ‘norm’ for decades. The B.O.S. answers this call with a BSAP-24 algorithm that can accurately predict and select the battery that needs additional energy to match the other batte

Frequently Asked Questions

What battery types are compatible with the BOS12V2 system?

The BOS12V2 system is approved for use with Wet Cell, AGM, and Lithium Ion batteries. For Lithium Ion batteries, it is recommended to verify compatibility with Pro Charging Systems and configure the BOS using PROView Link.

What is the primary function of the BSAP-24 algorithm?

The BSAP-24 Battery Selection and Prediction Algorithm is designed to accurately predict and select the specific battery within the pack that requires additional energy. This ensures all batteries match and remain balanced, extending their lifespan.

Can this system be used in both fresh and saltwater environments?

Yes, the Dual Pro Battery Optimization System is designed for use in both fresh and saltwater applications, making it suitable for various operational settings.

Does the BOS12V2 system consume significant power when not actively balancing?

No, the system features a less than 1mA sleep mode, indicating minimal power consumption when it is not actively shuttling energy between batteries.
