Meet the Dual Pro Battery Optimization System for Three 12V Batteries in Series (36V system) — a smart, self-powered solution that balances, protects, and extends the life of every cell in your 36V pack.

Model: BOS12V3. Approved for use with Wet Cell, AGM and Lithium Ion batteries. Designed for three 12V batteries in series to deliver reliable power in both freshwater and saltwater environments.

Key benefits

• BSAP-24 Battery Selection and Prediction Algorithm on board accurately predicts which battery needs additional energy to match the others, preventing premature pack failures.
• Extends the life of each battery in the pack and substantially increases run times.
• Sleep mode consumes less than 1 mA of standby current to minimize drain.
• Self-powered operation — no external power source required to run the optimization.
• Compatible with PROView™ Link battery monitoring software for real-time status via smartphone or tablet. Learn more about PROView™ Link capabilities on the Energy Management page.
• Designed to work with most Lithium batteries (always verify with PCS before use). Use PROView™ Link to configure BOS for approved lithium batteries.

Upgrade your 36V system with the BOS12V3 for balanced packs, longer battery life, and improved performance across wet cell, AGM, and lithium chemistries.
