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:

  • Build a quiet backup power kit in your truck, van or garage to keep fridges, lights, internet and medical devices running during outages

Asurion is AWESOME!
Ok, so let me start with the fact that you should NOT waste your time calling Amazon's customer service if you think you have a claim under Asurion's monthly protection plan. CALL ASURION! I wasted almost an hour with Amazon representatives that have absolutely no training in how the Asurion plan works, or even any idea if my item was covered. In fact, they told me the mechanized chair I purchased under the plan wasn't covered! Finally, my call got escalated to a manager who was just as clueless about my coverage, but had the best idea ever... call Asurion! The smartest thing I did that morning was hang up with Amazon, and reach out to Asurion as I should have done in the first place. Dealing with Asurion's customer service, after my Amazon call, was like being elevated to VIP status! 😄 Asurion's rep nicely took all my info, including the chair's purchase date and order number. Then they asked that I upload a couple of pictures of the product, along with a written description of the malfunction I had mentioned over the phone. This is where it gets really good. They told me they'd review the claim to determine if they'd send a repair specialist or reimburse me the cost of the item. In less than 48 hours, they determined that a payout was in order, and sent me an email that included an Amazon gift card for the total cost of the item minus the taxes I had paid, which I loaded directly into my Amazon wallet. Apparently, Asurion does not include the purchase taxes in their coverage. But, I can live with that. All in all, Asurion's claims division get a double thumbs up 👍🏽👍🏽, and the company gets big ups from me for not only standing behind their protection plan, but doing so expeditiously! Special note: If you buy a lot of stuff from Amazon, and have Asurion's monthly protection plan, scroll the item listing before pulling the trigger on your purchase... you need to see the green streamer that indicates your product is protected by the plan. If you don't see that, check to see if there are alternative products that might be covered. There are very few electronic or high ticket items that aren't covered, but looking for that green banner in the item description that says it's covered is key to foregoing any future headaches.

If they can't fix it they will replace it.
This protection plan that i pay monthly for paid for itself ten fold. My 3D printer just quit working and after the manufacturer warrenty had ran out at that. I submitted my claim they emailed me a shipping label in which I shipped out my printer that same day. Two days later they received my printer determined it couldc not be fixed and sent me a Amazon gift card for the full price of my printer. Today I will be receiving my new 3d printer thanks to Complete Protect. I highly recommend anyone and everyone to purchase this policy. This warrenty is like having a home warrenty like Homeshield but for your electronics and probably other stuff that i just have not read to see what else. This insurance will save me so much money over the corse of this year and every year after that. Thank you Complete Protect.

"Outstanding support and a seamless process!"
Great experience with Asurion insurance through Amazon. I wasn't sure how to register my items for the monthly plan, but the customer support team in the chat was incredibly efficient and guided me through the entire paperwork process smoothly. Furthermore, the service I received at the repair shop (Break Fix) was excellent. The whole process was seamless, and I received my digital gift card without any issues, which I’ve already applied to my Amazon account. I am very grateful for their professionalism and how easy they made everything. Highly recommended!"

Received giftcard money to replace my plan-protected malfunctioning motherboard
I've been subscribing to the Asurion protection plan for a while. Recently, an Asus Prime PC motherboard I had bought a few months ago on Amazon stopped working well. I ended up considering filing a claim with Asurion to see if they would either fix/replace it or issue the purchase price money, so I could buy the failed electronics replacement component again for my custom-built PC. I went to the protection plan's website and started the claim filing process but couldn't find the category my failed component would be under in order to select it from the drop-down list. I ended up messaging the live customer service. The chat messaging was somewhat slow, the agent told me they were experiencing some communication delays throughout their systems. Ultimately, the agent was very kind and understanding, and completed the claim filing process for me on her side by asking me to provide the necessary info such as the item's product name, date of purchase, price before taxes, etc. I received a printable UPS shipping label in the email, printed it, and returned the item in the mail. Approximately 2 days later, I received an Amazon giftcard code in the email with the dollar amount equal to the item's price before the sales tax. Then I redeemed the giftcard code on the Amazon page and proceeded to apply the giftcard money to my next purchase of a replacement Asus prime motherboard, and it all worked out successfully. Therefore, I had no issues with the protection plan service and recommend it to others.

Fast and easy but I dont trust the process to be fully automated.
The process was very smooth and fairly quick. The only challenge I had was that the CLAIM status showed complete but I had to manually go look up the status. There was no email or notification it was closed. After manually checking the status, I called customer support and they said since I called in, they would process the payout. I wonder if I didnt call in if they would have processed it? Also, the phone rep said they would issue me a amazon egift card but then the next day I received a email saying they mailed out the payout. Very poor communication but so far the process was easy and fast.
