12V 300Ah lithium battery. Power That Travels
The Vatrer 300Ah battery gives you steady 12V power when your RV, travel trailer, or off-grid cabin depends on more than a small backup pack. With 3840Wh of energy, a 200A BMS, and up to 2560W continuous discharge, this 12V 300Ah lithium battery keeps your fridge, lights, water pump, inverter, and small appliances running with confidence.
200A BMS. Safer Power Control
The built-in 200A BMS protects your battery from overcharge, over-discharge, short circuit, overcurrent, and high-temperature impact. It also balances internal LiFePO4 cells during use, so your 300Ah lithium battery stays stable, efficient, and ready for long-term RV solar, camping, and backup power setups.
Heated Lithium RV Battery For Winter
Cold weather should not stop your trip. As a heated lithium RV battery, this unit uses a built-in 90W self-heating system that starts when the battery temperature drops below 32°F and stops at 41°F, helping you charge safely during winter RV camping, mountain travel, or frosty off-grid mornings.
Bluetooth Monitoring. Know Your Battery
You should not have to guess how much power is left. Through the Vatrer app, Bluetooth monitoring lets you check voltage, current, temperature, and state of charge in real time, so you can manage your 12V 300Ah lithium battery from your phone before the fridge, lights, or inverter pull too much energy.
Expandable Power Up To 61.44kWh
Start with one battery, then grow when your power needs get bigger. The Vatrer 12V 300Ah battery supports up to 4S4P expansion, allowing a system up to 51.2V 1200Ah / 61.44kWh for larger RV solar banks, off-grid cabins, home backup systems, or long-term energy storage projects.
Flexible Charging For RV Solar
Your charging setup can change from campsite to campsite. This 300Ah lithium battery supports charging with a 14.6V LiFePO4 charger, RV solar panels, and DC-DC charging while driving, giving you flexible power recovery whether you’re plugged in overnight, parked under the sun, or moving between campgrounds.
300Ah Self-Heating Lithium Battery. Built Tough
Rain, dust, and humidity are part of real outdoor power use. With an IP65 waterproof housing, this 300Ah self-heating lithium battery is ready for travel trailer storage bays, RV solar systems, fishing cabins, and off-grid setups where weather and road vibration are part of the job.
Best Battery For Travel Trailer Freedom
When you’re parked at a lakeside campground in a 22 ft travel trailer or boondocking in a 30 ft RV, weak battery power gets stressful fast. This 300Ah lithium battery delivers deep-cycle energy for longer stays, helping you run essential 12V systems without the constant maintenance, voltage sag, or heavy weight of lead-acid batteries.
Quiet Power For Camping And Off-Grid Life
You can enjoy clean power without the noise and fuel smell of a generator. This 12V 300Ah lithium battery helps run camping lights, portable fridges, fans, routers, water pumps, and inverter-supported appliances, making it a strong choice for RV owners, travel trailer users, and off-grid homeowners who want dependable energy without constant upkeep.

TECH SPECS
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
Only had the battery installed for a few days now and so far it seems to be a great battery. I live full time in an RV and move approximately every 2 weeks. I originally had 2 wet cell deep discharge batteries. They were heavy and did not provide the longevity when experiencing a power outage. This battery fit my battery bay perfectly. I shed 45 lbs in weight and gained almost twice the capacity and close to 3 times the run time. The app is nice to see and works well. Although, some better instructions on what it tells me would be nice. Overall, I am very impressed with this battery.
Order two 300ah and will install tomorrow. Batteries arrived in perfect condition, both at 13.2 volts. Bluetooth worked great and showed all cells well balanced. Looking forward to some dry camping this weekend.
Thanks Vatrer!
This is an incredible battery and was a definite upgrade to our travel trailers solar system. I highly recommend Vatrer batteries.
Great battery. Would be good if would support app and monitor screen connectivity at the same time. Also seems the bms does not track low amp drain accurately. Otherwise great.
FAQs
A 12V compressor RV refrigerator usually uses about 40–80Ah per day, depending on size and weather. With 3840Wh / 300Ah capacity, the Vatrer 12V 300Ah lithium battery can typically support a 12V fridge in a 22–30 ft travel trailer for several days, while still leaving power for LED lights, fans, and water pumps.
Yes, one 300Ah lithium battery is a strong setup for many 20–30 ft travel trailers using a 12V fridge, LED lighting, roof vent fan, water pump, and phone or laptop charging. For heavy inverter loads like a microwave, induction cooktop, or rooftop A/C, you should check total wattage because this Vatrer battery supports up to 2560W continuous discharge.
Yes, the Vatrer 300Ah battery can replace multiple 12V lead-acid batteries in many RV and travel trailer setups, as long as the charger, wiring, and battery compartment are compatible. It weighs only 54.67 lbs, about 50% lighter than standard lead-acid batteries, while delivering deeper usable capacity and no watering or acid maintenance.
Yes, you should use a LiFePO4-compatible charger with a 14.6V charging profile. This battery also supports solar charging and DC-DC charging, which makes it suitable for RV solar systems, tow vehicles, and off-grid travel trailer setups.
Yes, this heated lithium RV battery is designed for cold-weather charging. Its 90W self-heating system starts below 32°F and stops at 41°F, while low-temperature protection prevents unsafe charging below 32°F until the cells are warm enough.
This battery has a 200A BMS and supports up to 2560W continuous discharge, so it pairs well with a properly sized inverter around 2000W - 3000W for common RV loads. For high-surge appliances like rooftop A/C units, large microwaves, or air compressors, always check startup wattage before connecting.
Yes, this 12V 300Ah lithium battery works well for small solar cabins, hunting cabins, and off-grid sheds running LED lights, a 12V fridge, router, fan, and small inverter loads. For larger systems, it supports up to 4S4P expansion, reaching 51.2V 1200Ah / 61.44kWh when installed with matching batteries and proper system components.
