Dual Pro PS3 3 Bank Battery Charger w/3 Bank B.O.S.

The Dual Pro PS3 3 Bank Battery Charger Kit, featuring the B.O.S. Battery Optimization System, is engineered specifically for marine and boating applications. This comprehensive kit ensures balanced power distribution, extends battery life, and maximizes performance on the water, keeping you powered longer and reducing the risk of battery failure.

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

The B.O.S. (Battery Optimization System) actively manages energy distribution between your batteries, ensuring each one remains balanced and operates at peak performance. By shuttling energy as needed, the B.O.S. extends the strength and longevity of your battery pack, providing quadruple run time on the water.

Batteries often become unbalanced, with the pack only as strong as its weakest link. This issue is exacerbated in marine applications where trolling motor batteries support peripherals or assist cranking batteries. The B.O.S. combats this by maintaining equal voltage across all batteries before, during, and after charging.

Utilizing the advanced BSAP-24 algorithm, the B.O.S. accurately predicts and selects which battery requires additional energy to match the others within the pack. This not only prolongs the life of each battery but also enhances overall run times.

Key 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
• Ultra-low power consumption with less than 1mA sleep mode
• High transfer rate up to 7.5A
• Self-powered for reliable operation
• Compatible with any battery chemistry

Ideal Applications for B.O.S.

• Marine and boating systems
• Golf carts
• Industrial battery setups
• Aerial equipment power
• Solar power storage
• Electric vehicles
• Communications infrastructure
• Defense and military applications
