More Power for Longer Trips
Running your refrigerator, lights, water pump, and inverter from a small battery bank can turn every overnight stop into an energy calculation. The Vatrer 12V 300Ah self-heating lithium battery provides 3,840Wh of energy and up to 2,560W of continuous output, helping you stay longer at campgrounds, boondocking sites, and off-grid cabins without constantly cutting back on essential power.
Stable Output When Loads Climb
When your refrigerator compressor starts or several appliances run together, an undersized battery may shut down or lose voltage. The built-in 200A BMS allows this Vatrer 12V 300Ah lithium battery to deliver steady power while protecting against overcharge, over-discharge, overcurrent, short circuits, and temperature extremes. Automatic cell balancing also helps the LiFePO4 cells age evenly through repeated use.
A Heated Lithium Battery for Winter
At temperatures below 32°F, charging standard lithium batteries can damage the internal cells. The built-in 90W heating system warms this heated lithium battery when temperatures fall below 32°F and stops at 41°F, allowing charging to resume safely. You can recharge with confidence during winter RV trips, mountain stays, hunting season, and freezing off-grid mornings.
Check Power From Your Phone
Open the Vatrer app to see how much energy remains before you settle in for the night or switch on a higher-demand appliance. Bluetooth monitoring displays the state of charge, voltage, current, temperature, and battery status of your 300Ah lithium battery in real time, helping you decide when to recharge or reduce power use without opening the storage compartment.
Grow Your Battery Bank Over Time
One battery may cover your current travel trailer, while a larger cabin or solar system may need more capacity later. This off-grid lithium battery supports configurations of up to 4 batteries in series and 4 in parallel, creating a maximum 51.2V 1,200Ah system with 61.44kWh of energy storage. You can begin with a simple 12V setup and expand without replacing your entire battery bank.
Recharge Wherever You Park
Campground hookups are not always available, especially when you travel between remote sites. This Vatrer 12V 300Ah lithium battery can recharge through a 14.6V LiFePO4 charger, a properly sized solar charge controller, or a DC-to-DC charger connected to your vehicle. You can recover power overnight, collect solar energy during the day, or charge while driving to your next stop.
Ready for Real RV Conditions
RV storage bays deal with road dust, damp air, vibration, and occasional water exposure. The IP65-rated enclosure helps protect this heated lithium RV battery from dust and water jets, making it suitable for covered RV compartments, travel trailers, fishing cabins, and fixed off-grid installations. You spend less time worrying about changing weather and more time enjoying the trip.
Use More of Your Stored Energy
Lead-acid batteries often provide limited usable capacity and require regular maintenance to avoid early failure. This 300Ah lithium battery supports an 80%–100% depth of discharge and more than 4,000 cycles, giving you more usable energy from the space in your RV. You can run essential equipment longer without checking fluid levels, cleaning terminals, or replacing batteries every few seasons.
Keep Off-Grid Life Quiet
A generator may keep your appliances running, but its noise, exhaust, and fuel can quickly take away from a peaceful campsite. This off-grid lithium battery quietly supports lighting, refrigerators, fans, routers, water pumps, and inverter-powered appliances. You can work, cook, or relax without disturbing nearby campers or carrying extra fuel.
Upgrade Before Your Next Getaway
Your next trip should not begin with another battery warning, a cold-weather charging problem, or a search for the nearest electrical hookup. Choose the Vatrer 12V 300Ah self-heating lithium battery now and prepare your RV or off-grid system before your travel plans begin. Install dependable power once, then spend your time deciding where to go next.

Just what I needed for’ boon-docking’!
The batteries were delivered on time. They work properly. The sizes were accurate. I received them in April in MN so ... ya, it was able to still solar charge under freezing temps. Very Happy
Other than Fed X delivering batteries 5 days apart everything else has been great. Installed in motorhome and they are staying balanced and recharge quickly. Bluetooth works great.
These batteries are great! Self heating! The app is amazing. I have already had a great experience with customer service. I’ve done a lot of research and these are the best Batteries!
Everything GOOD nothing bad. Delivered on time with 50% charge. Downloaded the app and immediately pulled up the batteries. App is flawless. After charging and balancing the batteries they were installed. I am very impressed. Vatrer is my go to battery.
Seems to be a great battery. When I tried to pull more than 200 amps, the BMS shut it down like it is supposed to do. 2 of them, in parallel, power my 3500 watt inverter perfectly. A lot lighter than 3 group 29 deep cell batteries.
Great power for our camper.
Easy ordering process, delivered ahead of schedule and installation and bluetooth pairing was easy. 10 days since installation and extremely pleased with everything.
Works great, the app is simple and works awesome
FAQs
The case measures 15.12 × 7.64 × 9.76 inches, weighs 54.67 lbs, and uses M8 terminals. Check your battery tray size, vertical clearance, and cable routing space before installing this Vatrer 12V 300Ah lithium battery.
Yes. Keep your RV system at 12V, use cables and protection rated up to 200A, and set your charger to a 14.2V–14.6V LiFePO4 profile. Disable equalization or desulfation modes, as they are not compatible with a lithium battery.
A 2,000W continuous inverter works well. At 90% efficiency, it draws about 174A, staying within the 200A BMS limit of this 300Ah lithium battery. Avoid pushing close to the 2,560W peak for long periods.
Charging takes about 15 hours at 20A, 7.5 hours at 40A, or 4.3 hours at 70A. A 70A LiFePO4 charger offers a good balance between speed and battery health for this 12V lithium battery.
Use 800W–1,000W solar panels with an MPPT controller to recover most of the 3,840Wh capacity in one day with good sunlight. A 400W system can add about 1.4–1.7kWh, better suited for topping up a 300Ah lithium battery.
No. The Vatrer 12V 300Ah self-heating lithium battery only activates its 90W heater when charging current exceeds 10A and temperature drops below 32°F. Heating stops at 41°F, so it won’t drain power while parked.
No. Use identical Vatrer 12V 300Ah self-heating lithium batteries in the same system. Mixing with non-heated or different lithium batteries can cause imbalance, uneven charging, or early shutdown.
No. This off-grid lithium battery is designed for deep-cycle energy storage, not engine starting. It does not provide CCA ratings. Use a dedicated starter battery for engines or generators.
Yes. A 1,500W load runs about 2.3 hours, and a 1,200W load runs about 2.9 hours on a full 300Ah lithium battery. For RV air conditioners, use a soft starter to reduce startup surge.
Keep the heated lithium RV battery at 30%–50% charge, disconnected from loads and chargers. Check monthly and recharge if it drops below 30%. Store between 14°F and 122°F, and protect the M8 terminals.
