The Renogy Pro S1 12V 120Ah Semi-Solid State LiFePO4 Battery is an advanced lithium iron phosphate battery built for RVs, vans, motorhomes, sailboats, cabins, and properly designed off-grid 12V battery systems where output, monitoring, and installation space matter. This battery provides 12.8V nominal voltage, 120Ah rated capacity, and a listed 150A maximum continuous discharge current for properly designed electrical systems. Renogy equips the Pro S1 120Ah with Intelligent Power Armor protection, self-heating support, Bluetooth monitoring, CAN communication, OTA update support, and an IP67 protection rating. Its 12.8" x 7.44" x 7.4" size and 29.5 lb listed weight help support compact installations, including under-seat layouts where Renogy’s clearance and access requirements are met. Final inverter sizing, charger settings, cable gauge, fusing, terminal torque, series or parallel configuration, and installation clearance should be confirmed against current Renogy documentation.
The Renogy Pro S1 120Ah battery is designed for users who want high-output 12V lithium storage in a compact case. Its 120Ah rated capacity, 12.8V nominal voltage, and 10.8V to 14.6V voltage range support properly configured RV, van, marine, cabin, and off-grid battery systems.
The Pro S1 120Ah is listed with a 120A maximum continuous charge current, 150A maximum continuous discharge current, and 350A peak discharge current for 30 seconds. Renogy’s Intelligent Power Armor battery management system is designed to apply protection based on different risk levels, helping the battery respond more precisely under supported operating conditions.
Renogy describes the Pro S1 series as offering up to 70% faster self-heating to help recover from low-temperature cut-off, with performance dependent on model and conditions. The battery is listed with a charge temperature range down to -4°F and a discharge temperature range down to -4°F, but cold-weather use should still follow Renogy’s charging, heating, and storage guidance.
Bluetooth monitoring helps users check battery data through the Renogy app, while CAN communication supports integration with compatible power-system equipment. Renogy lists enhanced Bluetooth range up to 32.8 yd / 30 m and over-the-air update support for easier monitoring and long-term battery management.
The Renogy Pro S1 120Ah battery is built for compact 12V power systems where output, monitoring, and cold-weather recovery support are important. It works best as part of a complete system with compatible chargers, inverters, fuses, wiring, and battery protection equipment.
Before installation, Renogy recommends clearance above the battery and additional side space near the busbars. Confirm mounting location, terminal torque, cable sizing, charging settings, communication setup, and environmental exposure before use.
