Meet the Dual Pro Battery Optimization System for Four 12V Batteries in Series in a 48V system—model BOS12V4—engineered to balance, protect, and extend the life of every cell in your pack.
With the on‑board BSAP‑24 Battery Selection and Prediction Algorithm, the BOS identifies exactly which battery needs a nudge of energy to match the others, preventing premature failure due to imbalance and delivering longer run times across the pack.
Key benefits
-
Balanced performance for a four‑cell 48V system: precisely manages energy across four 12V batteries connected in series, maximizing capacity and longevity.
-
Broad battery compatibility: approved for Wet Cell, AGM and Lithium Ion batteries; designed for 12V batteries; safe for use in both fresh and saltwater environments.
-
Low power and self-powered: sleep mode consumes less than 1 mA, keeping energy draw negligible while preserving battery life.
-
Self-powered and reliable: the unit powers itself in operation, ensuring continuous optimization without draining your pack.
-
PROView Link integration: compatible with PROView™ Link battery monitoring software, so you can monitor status from your smartphone or tablet. The app is free on the Apple App Store and Google Play.
Note for lithium users: Always verify compatibility with PCS before using with lithium batteries. Use PROView™ Link to configure B.O.S. for use with approved lithium batteries.
Take control of your 48V system, extend battery life, and enjoy longer run times with the Dual Pro Battery Optimization System—the smart, on‑board solution that keeps every cell in balance and your power ready when you need it most.
