When you’re running an RV full-time, powering a mobile office, or living off the grid, power isn’t optional—it’s everything. That’s why the 12V 1200Ah LiFePO4 battery was built for the real demands of real-world use. With over 15.4kWh of stored energy, this high-capacity lithium iron phosphate battery delivers round-the-clock performance for big loads, long stays, and extreme environments.

Built for Big Power. And Bigger Adventures.

This isn’t just another battery. The 12V 1200Ah deep cycle lithium battery is engineered for people who depend on electricity—whether you’re traveling cross-country in a motorhome or running field equipment in harsh weather.

High Capacity Output

With 350A continuous discharge and up to 6000W inverter compatibility, you can run multiple heavy-duty appliances at once—think air conditioners, induction cooktops, microwaves, or even sensitive medical devices.

Long-Lasting Performance

Thanks to premium Grade A LiFePO4 cells, you’ll get over 5000 charge cycles at 80% depth of discharge. That’s 10+ years of dependable energy, far outperforming AGM or lead-acid batteries.

Fast Charging, Any Way You Like

Compatible with solar, alternator, and shore power. Whether you’re in a cabin, camper van, or trailer, you can recharge this 12V 1200Ah lithium battery fast—so you stay off-grid longer.

Built-In Smart BMS

It’s not just powerful—it’s smart. The integrated Battery Management System (BMS) protects against overcharge, short circuits, overheating, and more. Some models offer Bluetooth monitoring, so you can check health and charge levels in real-time.

Works in the Cold

With an optional self-heating BMS, the battery stays functional even in sub-zero temps. Ideal for polar expeditions, high-altitude trailers, or winter off-grid setups.

Typical Uses

This 12V LiFePO4 battery for RV and mobile power fits a range of demanding applications:

Commercial RV and camper van conversions
Mobile clinics or workstations
Emergency command vehicles
Marine or tiny house energy systems
12V lithium battery for off-grid solar arrays (6kW+ recommended)
Backup for scientific research or extreme environment use

User Scenarios

Polar Research Station

In sub-zero temperatures down to -50°C, the battery powers LIDAR systems, satellite modems, and meteorological equipment—without fail.

Emergency Response Vehicles

In post-disaster zones, this battery supports 24/7 operation of life detectors (800W), satellite comms (1200W), and portable medical units (1500W) during the crucial first 72 hours.

Space-Saving, Maintenance-Free, Eco-Friendly

Compared to multiple AGM units, the 12V 1200Ah lithium iron phosphate battery saves space, sheds weight, and requires zero maintenance. It’s fully sealed, leak-proof, and free of toxic heavy metals—making it the best 12V LiFePO4 battery for environmentally-conscious users.

How long will a 12V 1200Ah LiFePO4 battery last in my RV?

Depending on your appliances, it can power a full RV setup for 3–5 days without recharge. With solar, it can last indefinitely.

What’s the difference between this and an AGM battery?

LiFePO4 batteries like this one are 6–8 times longer-lasting, lighter, charge faster, and require no maintenance.

Can I replace multiple lead-acid batteries with one 12V 1200Ah lithium battery?

Yes. This battery replaces multiple AGM or gel batteries, saving space, weight, and long-term cost.

What can a 12V 1200Ah LiFePO4 battery run in my RV?

With 15.4kWh capacity, this battery can power large appliances like air conditioners, induction cooktops, microwaves, medical devices, and entertainment systems—all running at once if needed. It’s a true off-grid solution for full-time RV living or commercial setups.

Is it safe to install in a confined space?

Yes. The built-in smart BMS manages temperature, voltage, and current automatically. For best results, ensure ventilation around the battery to help it stay cool under heavy loads.

How fast can I charge the 12V 1200Ah lithium battery?

It supports high-speed charging from solar panels, alternators, or AC chargers. With a compatible charger, you can recharge in under 6–8 hours, depending on the input power.

Can I replace my AGM or lead-acid battery with this model?

Absolutely. This battery is designed as a drop-in replacement for traditional 12V banks. It’s lighter, maintenance-free, and far longer-lasting.

Does it work in freezing weather?

Yes. An optional low-temperature heating function in the BMS keeps the battery performing in temperatures as low as -30°C, making it perfect for polar expeditions or winter RV camping.

Do you offer custom configurations or bulk orders?

We do. We can build a custom 12V LiFePO4 battery pack to fit unique layouts or provide bulk pricing for OEM and wholesale projects.
