Rolls VB12-100LFP 12V 100Ah LiFePO₄ Battery Key benefits 12V 100Ah LiFePO₄ battery in a standard BCI Group 24 case, ideal as a drop‑in replacement for many VRLA batteries in off‑grid, backup and mobile systems. Long service life with an expected 6000 cycles at 80% depth of discharge, helping to reduce replacement and maintenance costs over time. Integrated hardware BMS with multiple protection functions plus Bluetooth connectivity and dedicated iOS/Android app for easy monitoring. Brief description The Rolls VB12-100LFP 12V 100Ah LiFePO₄ Battery is part of the Rolls VB Series LFP range and is designed as a robust, maintenance‑free alternative to traditional 12V lead‑acid batteries. With a nominal energy of 1.28kWh, up to 6000 cycles at 80% DOD and an IP65‑rated ABS enclosure, it suits small commercial backup systems, telecoms, remote monitoring, mobile power and off‑grid applications. Integrated BMS and Bluetooth connectivity simplify protection, status checks and fleet management in multi‑battery systems. Key features 12.8V nominal, 100Ah rated capacity and 1.28kWh total energy in a compact Group 24 footprint. Standard‑size BCI ABS container with integrated top‑mount handles for straightforward VRLA replacement and handling. Heating for low‑temperature operation and wide charge/discharge temperature range from -20°C to +55°C. Integrated BMS with independent charge and discharge protection, including over‑voltage, low‑voltage, over‑current, short‑circuit and temperature protections. Up to 4 in series and 4 in parallel (4S4P at 48V) for modular system building in DC storage banks.
