The Renogy Pro S1 12V 120Ah Semi-Solid State LiFePO4 Battery is a compact lithium iron phosphate battery built for RVs, vans, motorhomes, sailboats, cabins, and properly designed off-grid battery systems where output, monitoring, and space planning matter. This battery provides 12.8V nominal voltage, 120Ah rated capacity, and a listed 150A maximum continuous discharge current for properly designed 12V power systems. Renogy equips the Pro S1 120Ah with Bluetooth and CAN communication, Intelligent Power Armor battery protection, self-heating support, and IP67-rated protection. Its 12.8" x 7.44" x 7.4" size and 29.5 lb listed weight support compact installations, including under-seat layouts for the Pro S1 120Ah model when Renogy’s required clearance is met: 1.97–3.94 inches above the battery and at least 7.87 inches on the busbar side. Final system design, inverter sizing, charging profile, cabling, fusing, ventilation clearance, series or parallel configuration, and installation location should be confirmed against current Renogy documentation.
The Renogy Pro S1 120Ah battery is designed for users who need dependable 12V lithium storage in a smaller package than many traditional batteries. Its 120Ah capacity, 12.8V nominal voltage, and 10.8V to 14.6V voltage range support properly configured RV, van, marine, cabin, and backup 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 risk levels, helping support safer operation under supported load and charging conditions.
Renogy describes the Pro S1 series as having faster self-heating to help recover from low-temperature cut-off. Renogy lists charge and discharge temperature ranges down to -4°F, but cold-weather charging should follow Renogy’s self-heating, battery management system, and charger-profile instructions.
Bluetooth monitoring helps users check battery information through the Renogy app, while CAN communication supports integration with compatible system equipment. Renogy lists enhanced Bluetooth range up to 32.8 yd / 30 m and over-the-air update support for easier monitoring and ownership management.
The Renogy Pro S1 120Ah battery is built for compact 12V power storage where space, output, and monitoring matter. It can support mobile and off-grid systems when paired with compatible chargers, inverters, cables, fuses, and system protection.
Before installation, Renogy recommends clearance above the battery and additional side space near the busbars. Confirm mounting location, terminal torque, cable sizing, charging settings, and environmental exposure before placing the battery into service.
