Ultra Slim 12V 104Ah Lithium Battery for Overlanding, RV and Off Grid Backup Power

If you are fighting for space in a 4x4 canopy, RV cabinet or van build, this ultra slim 12V 104Ah lithium iron phosphate battery is built to fix that problem. At only 2.4 inches thin, it gives overlanders, RV owners and off grid homeowners serious, long life power in spaces where a normal battery simply will not fit, while cutting weight, noise and fuel hassle compared to lead acid and small generators.

12V 104Ah Slim Lithium Battery Solves Tight Space Problems

The problem:
Modern overland and off grid setups run fridges, lights, radios, fans, pumps and a solid inverter. The gear list keeps growing while your battery space does not. Traditional lead acid or even standard lithium cases eat up your storage, force awkward installs and often end up underpowered or badly mounted.

The solution:
This 12V 104Ah super slim LiFePO4 battery is just 2.4 in / 61 mm thick with vibration resistant bracket kits included. It slides behind truck seats, into canopy wings, under platform beds, or in shallow RV and van cabinets, all while staying solid on washboard roads and trails.

The outcome:
You free up real room for recovery gear, water, tools and family camping gear, without giving up capacity. Your wiring is cleaner, the install is safer, and you gain usable storage instead of losing it to a bulky battery box.

• Thickness: 2.4 in / 61 mm
• Dimensions: 22.8 × 11.4 × 2.4 in / 579 × 290 × 61 mm
• Weight: 28.22 lb / 12.8 kg
• Includes 2 x battery bracket kits for secure mounting

Replace Heavy Lead Acid with Safe Solid State 12V LFP Power

The problem:
Lead acid and AGM batteries are heavy, waste capacity if you discharge them too deep, hate vibration, and lose performance in the cold. Worst case, they fail when you actually need them, leaving your fridge, lights and critical devices dead. Small gas generators add noise, fumes and more fuel to manage.

The solution:
This 12V 104Ah solid state lithium iron phosphate battery is designed as a drop in upgrade for 12 V systems, with a 9x slower temperature rise that helps reduce thermal runaway risk and improve safety. LFP chemistry gives long cycle life, stable output and much more usable capacity per pound than lead acid.

The outcome:
You get a lighter, safer, longer lasting power source that you can rely on when storms hit at home or when you are days down a dirt road. Less maintenance, less fuel juggling, more confidence.

• Chemistry: Lithium Iron Phosphate (LFP), solid state design
• Cycle life: up to 6000 cycles at 80% depth of discharge to 80% end of life
• Protection rating: IP67, dust tight and protected against temporary immersion
• Certifications: MSDS, UN38.3, FCC, CE, PSE, RCM, IC, RoHS, UKCA

High Output 12V Lithium Battery to Run a 2000W Inverter

The problem:
Many “compact” batteries fall apart when asked to run real loads like induction cooktops, microwaves, air compressors, power tools or small AC units through an inverter. Voltage sags, inverters trip and you end up babysitting your system.

The solution:
This ultra slim 12V 104Ah battery is built to deliver serious current:

• Maximum charge current: 100 A
• Maximum continuous discharge current: 200 A
• Peak discharge current: 290 A for 30 seconds

A single battery can power a 2000 W inverter within rated output, giving you real AC power in a very small footprint.

The outcome:
Overlanders, RV owners and off grid homesteaders can run the gear they actually want to use, not just lights and a small fridge. Coffee makers, small tools, pumps and emergency loads are on the table, without dragging a generator out in bad weather.

Cold Weather 12V Lithium Battery for Storms, Freezes and Winter Trips

The problem:
Many lithium batteries refuse to charge properly in the cold, exactly when suburban homeowners and off grid users need backup power the most. Standard chemistries either shut down or take damage if charged below freezing.

The solution:
This battery is rated for reliable 10 A charging in freezing conditions down to 14°F / -10°C, and keeps working across a wide temperature range:

• Charge temperature: 14°F to 131°F / -10°C to 55°C
  • From 14°F to 32°F / -10°C to 0°C, charge at 0.1 C (about 10 A)
• Discharge temperature: -4°F to 140°F / -20°C to 60°C
• Storage temperature: -4°F to 140°F / -20°C to 60°C

The outcome:
For the resilient suburban homeowner, this means your truck, van or RV based power system can stay ready as a quiet backup during winter grid failures. For the off grid homesteader, winter pumping, lighting and communications stay online without babysitting batteries or dragging out noisy generators.

Off Grid Ready 12V Lithium Battery for Series and Parallel Bank Builds

The problem:
Off grid systems and serious overland rigs often need more than one battery. Mixing and matching or working within tight connection limits can turn into a wiring headache and limit your upgrade path.

The solution:
This 12V 104Ah LFP battery is designed for flexible bank configurations:

• Series and parallel: up to 4P4S
• Parallel only: up to 16P
• Series only: up to 4S

Terminal hardware is included with clear torque specs for a solid connection:

• Terminal bolts: M8 x 1.25 x 12 mm (2)
• Long terminal bolts: M8 x 1.25 x 16 mm (2)
• Recommended terminal torque: 70.8 in lb / 8 N·m

The outcome:
You can start with a single ultra slim battery for a compact rig, then scale to multi battery banks for cabins, larger RVs or homesteads using the same model. Fewer compatibility surprises, cleaner installs and easier troubleshooting.

12V 104Ah Ultra Slim Battery Use Cases for Our Core Customers

For the prepared suburban homeowner:
