The Rolls S-Series S12-100LFP LiFePO4 drop-in battery combines the convenience and high performance of lithium technology with premium features designed specifically for installers. Housed in compact, lightweight, standard-size BCI cases, the S-Series provides a true drop-in replacement for VRLA batteries, simplifying upgrades and installations. Each S-Series LFP model features an integrated onboard display that provides a clear visual indication of state of charge, voltage, and system alerts. A removable case cover allows for serviceability*, while the unique external fuse access enables quick and convenient on-site fuse replacement when required. The built-in Battery Management System (BMS) delivers comprehensive operating protections and supports up to 1C charge and discharge capability. Integrated heating enables safe charging in low-temperature environments, supporting operation from -20°C (-4°F) to 0°C (32°F)—an essential feature for cold Canadian winters. With built-in Bluetooth connectivity and the Rolls LFP Connect mobile app available for iOS and Android, installers and homeowners can easily monitor battery status, access product documentation, and connect directly with Rolls Technical Support through the integrated support ticket system.
