With strong peak output, they enable simultaneous operation of microwaves, blenders and high-power appliances. So you don't have to compromise comfort all year round. *Based on the Pro S1 240 model.

Your Winter Comfort, Uninterrupted.

Don't let a frozen battery leave you in the cold. With its high-wattage heating pads, the Pro S1 batteries recover from low-temperature protection up to 70% faster*, guaranteeing a steady flow of power to keep you warm and meals hot during frigid days. *Based on the Pro S1 240 model.

Built Tough for Any Trail

From city streets to rough trails, Renogy Pro S1 series batteries conquer them all. The rugged shockproof construction and brackets provide a firm grip for batteries to ensure reliable power even off the beaten path.

Power That Lasts

Coupled with an ultra-long lifespan of 6,000 cycles (retaining 80% capacity), the Pro S1 series batteries can deliver 16+ years of reliable power with one full charge cycle per day. Plus, enjoy up to 7 years of warranty for long-term peace of mind.

Unparalleled Stability

With 9 times slower temperature rise compared with traditional liquid lithium batteries, the Pro S1 series reduces the risk of thermal runaway when operating in high temperatures.

Multi-Level BMS Protections

The intelligent battery management system (BMS) deploys targeted defenses at different levels of risk. Rather than shutting everything down at once, the BMS applies the right safeguards when needed to keep your battery safe and power steady.

Built to Deliver Power Anywhere, Anytime

Fire-Retardant

Made of UL94 V-0 flame-retardant materials, the Pro S1 batteries can handle high temperatures and even 10-second burning without dripping or causing open flames.

IP67 Dustproof & Waterproof

Designed to conquer harsh environments, the Renogy Pro's IP67-rated enclosure blocks dust & water – ensuring reliable operation through sandstorms, heavy rain, or accidental splashes.

Seawater-Resistant

Engineered with marine-grade armor, Pro S1 batteries pass 24-hour salt spray tests – making them ideal power sources for sailboats, coastal homes, and offshore adventures.

Steady Data Streaming

Thanks to the enhanced Bluetooth technology, you can consistently keep track of battery stats at a maximum range of up to 32.8 yd / 30 m.

At-a-Glance Monitoring

Easily view real-time stats like voltage, current, remaining capacity, and heating status. Get instant alerts about potential risks to stay worry-free whether you're navigating miles off-grid or open waters.

Over-the-Air Update

Keep your battery at its best with new features and improvements by connecting it to the Renogy app through Bluetooth.

Set up a Stable Power System via Wired Connection

Maximize Your Limited Space

Save space with Pro S1 batteries that pack more energy into a smaller, lighter build. They fit neatly in motorhomes or sailboats–under seats (Pro 120Ah model), on the floor, or in cabinets–for a clean installation.

FAQ

Does the solid state battery contain 100% solid electrolytes?

No. Currently, there are no 100% solid-state batteries available on the market. Our semi-solid battery cells reduce liquid electrolyte by approximately 70% compared to conventional lithium-ion batteries. This helps to provide a safer, more stable, and higher-performing power source for your full-time off-grid living.

What is the maximum output of this lithium battery?

Renogy Pro S1 12V 120Ah Battery can discharge at 150A (1.25C), considering 120Ah capacity. This means one single battery is able to output 1920W continuously and 2112W peak power for 60s. It can work with a 1800W inverter to power esential appliances through your tough adventures.

Do I need to use a BT module to monitor the status on my phone with Renogy smart app?

No. The battery has built-in Bluetooth, so you can track status in real time through the Renogy app. It also includes CAN ports for simple communication between devices.

How to recharge my solid state batteries?

You can charge them with solar, a DC-DC charger, or an AC-DC charger. We recommend using a controller or charger designed for LiFePO4 batteries.

What is the life expectancy of this battery?

About 6000 cycles at 80% depth of discharge, depending on temperature and storage conditions.

Please explain the multi-stage discharge overcurrent protection (165A/1min → 240A/30s → 360A/200ms). Why not use a single hard cutoff?

Thisgraded responsebalances protection with usability:
● 165A/1min: Allows for sustained overloads (e.g., inverter surge) without nuisance trips.
● 240A/30s: Permits brief motor starts (e.g., RV AC compressors).
● 360A/200ms: Hard cutoff for dead shorts (1000A/110µs).

Is this battery waterproof?

Yes, the battery is IP67-rated, which means it can be submerged in water up to 1 meter / 39.37 inch deep for up to 30 minutes.
