Vatrer 12V 300Ah Heated Lithium Battery with 300A BMS and Cooling Fan for RVs
Vatrer 12V 300Ah Heated Lithium Battery with 300A BMS and Cooling Fan for RVs
- Power High-Demand RV Loads with Confidence: A 300A BMS gives this 12V 300Ah lithium battery the continuous current capacity needed for high-power inverters and demanding RV appliances. It is built for users who need more than basic house-load support.
- Keep High-Current Operation Cooler: This lithium battery with cooling fan actively removes heat from the BMS during sustained high-current discharge. The design helps maintain stable operation when heavy loads run for extended periods.
- Stay Off-Grid Longer Between Charges: With 3840Wh of stored energy, this 300Ah RV battery provides a substantial reserve for refrigeration, lighting, cooking equipment, and other daily RV loads. Fewer recharge interruptions mean more usable time away from hookups.
- Restore Charging Automatically in the Cold: This 12V 300Ah self-heating lithium battery uses incoming charging power to warm the cells when temperature reaches 32°F below. Heating is handled automatically before normal charging resumes.
- Manage Battery Status from Your Phone: Bluetooth app monitoring gives you direct visibility into SOC, current, temperature, power, cycle information, and cell status. You can track battery condition and energy use without relying on voltage estimates alone.
- Recharge Around Your Travel Routine: Use shore power, solar charging, or a generator-based charging setup depending on where you are parked. Multiple charging paths make the battery practical for campgrounds, boondocking, and extended off-grid travel.
- Built-In Protection for Demanding Use: The integrated BMS manages over-current, short-circuit, over-charge, over-discharge, and temperature protection automatically. This added control is especially important in high-current RV and off-grid power systems.
- Expand Beyond a Single Battery: Support for up to 4S4P gives you room to build a larger battery bank as your solar, inverter, or backup-power requirements grow.

Run High-Demand RV Loads with 300A Continuous Output
When your microwave, coffee maker, air conditioner, or inverter is running, current demand can rise quickly. This Vatrer 12V 300Ah lithium battery uses a 300A BMS to deliver the high-current output needed for demanding RV electrical systems. You get strong continuous output from one 300Ah battery for everyday RV appliances and high-power inverter use.
Active Cooling for Sustained High-Current Loads
During extended high-current discharge, heat builds around the MOSFETs and other components inside the BMS. This lithium battery with cooling fan actively moves heat away from the 300A BMS board to reduce heat buildup during sustained loads. Its SPCC housing provides a durable enclosure for RV and off-grid power use.
3840Wh for Longer RV Days
From morning coffee to evening lighting, a day away from hookups can keep your refrigerator, fans, cooking equipment, and other appliances running for hours. With 3840Wh of stored energy, this 300Ah RV battery gives you a larger reserve for those daily loads and helps reduce how often you need shore power or generator charging. One large house battery also keeps your RV power setup simpler than managing several smaller batteries in parallel.
Cold-Weather Charging That Starts Automatically
On a freezing morning, charging can begin with the battery warming itself from the incoming charging source. This 12V 300Ah self-heating lithium battery directs charging input to the internal heating film when cell temperature is at below 32°F. Once the temperature rises above 41°F, heating stops and normal charging begins automatically.
Recharge from Shore Power Solar or a Generator
At a campground, you can recharge with a 14.6V 40A LiFePO4 charger. During off-grid stays, solar panels paired with an MPPT controller can turn daytime sun into stored energy for the next night. When solar production is limited, a generator can recharge the battery through a DC-to-DC charger.
Battery Status at a Glance in the Vatrer App
After several hours of running your refrigerator, inverter, and other loads, you can open the Vatrer app and see what is happening inside the battery. The app displays SOC, current, temperature, power, cycle information, and individual cell status. You can check remaining energy and see how your electrical loads are affecting the battery in real time.
Built-In Protection for Changing Loads and Temperatures
As appliances cycle on and off throughout the day, the current flowing through your RV system changes with them. The built-in BMS automatically manages over-current, short-circuit, over-charge, over-discharge, and high- and low-temperature protection as operating conditions change.
Room to Grow Up to 4S4P
If your RV or off-grid setup grows over time, the battery can be used in configurations up to 4S4P. This gives you room to expand beyond a single 12V battery as you add more solar capacity, inverter power, or backup energy storage.
Power Your Next Trip with More Confidence
A 300Ah battery should do more than store energy when your RV depends on it for high-current appliances, cold-weather charging, and long off-grid stays. This model combines a 300A BMS, active cooling, self-heating, and app-based monitoring in one battery built for demanding 12V power systems. Order yours today and put more usable power behind your next trip.
