Battery Optimization System (B.O.S.) - 12V - 4-Bank
The Pro Charging Systems Battery Optimization System keeps batteries balanced enabling maximum performance. The system can quadruple run time on the water for boaters and other users.
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.
The Battery Optimization System is the perfect companion device to utilize with Pro Charging Systems advanced battery chargers.
B.O.S. is compatible with PROView™ Link battery monitoring software that enables you to monitor your battery status via your smart phone or tablet. The PROView™ Link App is available to download for free at the Apple and Google Play stores. Learn more about the capabilities of PROView™ Link at the Energy Management page.
Applications: Inland Watercraft, Saltwater Watercraft, Motorhomes, Industrial, Golf Carts, Utility Carts and more.
