Ryobi 40V 6.0 Ah Lithium-Ion Battery
The alternating red and green flash is the Battery Management System (BMS) indicating a hardware fault, most frequently caused by deep discharge or internal cell imbalance. When individual cell groups within the pack vary in voltage beyond a specific threshold, the BMS enters a permanent lockout mode to prevent fire hazards during charging. Replacing the battery pack is the only standard method to restore functionality to the mower as the internal logic boards are not user-resetable.
