12V 120Ah & 240Ah Pro S1 LiFePO4 Batteries for High-Demand RVs and Off-Grid Rigs
If your rig is packed with energy-hungry appliances and you’re tired of choosing between comfort and battery life, the Renogy Pro S1 series 12V 120Ah and 12V 240Ah LiFePO4 batteries are built for you. These packs are designed to deliver over 3000W of output with strong surge power, so running air conditioning, a coffee machine, hair dryer, microwave and blender is just “normal use,” not a special occasion.
Built to Run Real Household Loads On the Road
Pro S1 batteries are engineered to keep up with modern motorhomes and off-grid systems. With high continuous and peak output, they can run 99% of typical RV and camper appliances, and handle multiple big loads at once. That means:
- AC running while someone makes coffee
- A microwave or induction cooktop starting without dimming lights
- Hair dryers, kettles and space heaters within the inverter’s limits
You get grid-like power from a 12V battery bank, instead of nursing every switch.
Winter-Ready Power with Fast Self-Heating
Cold weather is where many lithium batteries tap out. Pro S1 batteries lean into it instead.
High-wattage self-heating pads help the battery recover from low-temperature cut-off up to 70% faster than conventional packs. As soon as safe charge current is available, the battery warms itself and comes back online, so you are not stuck with a frozen bank when you need heat, cooking and lights the most.
Low-temperature charge and discharge protection is built into the BMS. It cuts off charging or discharging before cold can damage the cells, then resumes normal operation when temperatures return to a safe range. You get real winter usability without sacrificing long-term health.
Tough Enough for Long Roads and Rough Trails
Pro S1 batteries are built to live where RVs and overland rigs actually go.
A shockproof construction with dedicated mounting brackets keeps each battery firmly in place, resisting vibration and impacts from potholes, washboard roads and uneven tracks. The housing carries an IP67 protection rating, keeping dust and water out so the pack can ride in under-seat compartments, exterior storage bays and utility spaces without needing a climate-controlled environment.
The 12V 120Ah model is sized to tuck neatly under seats and in tight cabinetry, making it a great fit for vans and smaller motorhomes where every cubic inch counts. The 12V 240Ah model doubles the capacity for larger RVs and off-grid systems that need deeper reserves.
Power That Lasts for 16+ Years
Inside each Pro S1 battery are LiFePO4 cells rated for 6000 cycles at 80% depth of discharge. At one cycle per day, that is well over 16 years of service before the pack reaches 80% of its original capacity.
For most real-world RV and off-grid use, that translates into:
- A bank that outlives several vehicles or build iterations
- Far fewer replacement hassles compared with lead-acid or low-end lithium
- Stable, predictable performance for the long term
Backed by up to 7 years of warranty, Pro S1 batteries are meant to be a long-term anchor for your power system, not a consumable.
Intelligent Protection with IPA and Smart BMS
Instead of a simple on/off safety cutoff, Pro S1 batteries use a multi-level battery management system combined with Intelligent Power Armor (IPA) technology.
The BMS:
- Watches for over-current, over-voltage, under-voltage, short circuits and thermal issues
- Applies graduated protections depending on the severity of the risk instead of just killing power at the first hint of trouble
- Helps keep your battery safe and your appliances running steadily when conditions are still within safe limits
Communication is built in, with Bluetooth and CAN support for integration with compatible monitors and systems. You also get 1.6x longer Bluetooth range and OTA (over-the-air) firmware updates, so protection logic can be improved over time without pulling the battery.
12V 120Ah vs 12V 240Ah – Pick Your Power
Pro S1 12V 120Ah LiFePO4 Battery
- Ideal for under-seat installs, vans, compact motorhomes and mid-size systems
- 120Ah capacity, 12.8V nominal
- 120A max continuous charge, 150A max continuous discharge
- 350A peak discharge for 30 seconds for tough startups
- Compact size: 12.8 x 7.44 x 7.4 in, about 29.5 lb
Pro S1 12V 240Ah LiFePO4 Battery
- Best for larger RVs, fifth wheels, toy haulers and off-grid cabins that need a deeper well of energy
- 240Ah capacity, 12.8V nominal
- 240A max continuous charge and discharge
- 450A peak discharge for 30 seconds for even heavier loads
- Size: 15.94 x 9.61 x 7.4 in, about 56.2 lb
Both models share the same 6000-cycle life, IP67 protection, wide temperature operating range from -4°F to 140°F for discharge, and connection flexibility up to 4S4P (when building higher voltage or larger banks with matched units).
