M18 REDLITHIUM XC5.0 Extended Capacity Battery Pack
The internal Battery Management System (BMS) has engaged a safety lockout because it detected a voltage differential between cell banks that exceeds the charging tolerance. This typically occurs when the pack is deeply discharged and one bank reaches the Under-Voltage Lock-Out (UVLO) threshold before others, rendering the pack invisible or 'faulty' to the OEM charger. Replacing the full assembly ensures all cells are balanced and the protection circuit is reset for proper communication with the charger's logic.
