Vatrer 36V to 12V Golf Cart Power Buck Converter, 25A/335W DC to DC Voltage Reducer

Reliable Heated Power for RV, Solar, and Backup Systems If you're searching for a dependable energy solution to power your RV, solar setup, or home backup system, the Vatrer 12V 300Ah RV lithium battery with its 300A BMS and cooling fan might be just what you need. This 12V 300Ah LiFePO4 battery shines with its innovative self-heating feature and built-in cooling design, offering reliable power even in challenging conditions. Whether you're gearing up for an off-grid adventure or preparing for unexpected outages, this heated LiFePO4 battery 12V 300Ah can meet your usage needs with confidence. Long-lasting Performance with Smart Safety Features This Vatrer 12V 300Ah LiFePO4 battery is built to last, offering over 5,000 charge cycles and a lifespan exceeding 10 years. The heart of its durability lies in the built-in 300A Smart BMS, which includes advanced safety features like protection against overcharge, overdischarge, overcurrent, short circuits, and temperature extremes. The high-temperature cutoff activates if things get too warm, while the 12V lithium battery low-temp charging protection works alongside the self-heating system to keep performance steady. It also maintains a low 3% self-discharge rate, preserving energy during storage. Paired with a cooling fan that activates at 114.8°F and turns off below 111.2°F, this setup ensures the battery stays in top shape, even under heavy use. Efficient Self-Heating and Cooling Technology One of the standout features of this 12V 300Ah RV lithium battery is its automatic self-heating function. With a 110W heated lithium pad, it doubles heating efficiency, activating when temperatures drop below 32°F as long as the charging current exceeds 10A. The BMS detects the cold, triggers an internal heating film to warm the cells, and stops at 41°F to switch to normal charging. This makes it ideal for cold climates where traditional batteries might fail. Combined with its cooling fan, it becomes a highly reliable self-heating lithium battery 12V for winter RV travel and off-grid living. Smart Monitoring with Bluetooth Connectivity Stay in control with the Vatrer 12V 300Ah LiFePO4 battery and its Smart Bluetooth 5.0 feature. Connect to the Vatrer app for real-time insights such as battery percentage, remaining capacity, voltage, current, power, individual cell voltages, temperature, and cycle count. You can switch discharge on or off, turn the battery on or off remotely, and check system health with ease. This level of monitoring is perfect for users who rely on a heated LiFePO4 battery 12V 300Ah and need precise control in extreme environments. Powerful Energy Output This 12V 300Ah RV lithium battery delivers a solid 3,840Wh of energy and 3,840W of output, with a maximum continuous discharge of 300A and a 500A peak for 3 seconds. It also supports a 300A maximum continuous charging and discharge capacity per unit, making it a versatile choice for various power needs, from RV air conditioners to off-grid inverters. Flexible Capacity and Charging Options The Vatrer 12V 300Ah LiFePO4 battery offers scalable capacity and versatile charging. Up to 4 batteries can be connected in series to create a 48V (51.2V) system, or up to 10 in parallel for a total capacity of 3,000Ah. This scalability is especially useful when building a 12V 300Ah RV lithium battery energy bank for cold-weather use. Charging is flexible as well: a 14.6V 40A AC charger takes about 7.5 hours, an ~850W solar system with an MPPT controller can recharge it in about 4-5 hours of effective sunlight, and using a generator equipped with a 40A DC-DC charger, the charging time also takes 7.5 hours. Compact Design and Portability Durable As a heated LiFePO4 battery, this Vatrer 12V 300Ah is designed with practicality in mind, measuring 15.51 × 8.27 × 11.69 inches and weighing 71.65 lbs. Its built-in handle makes it easy to move, while secure M8 terminal bolts ensure stable installation. With an IP65 waterproof rating and a sturdy SPCC metal casing, it stands up to tough weather conditions. Perfect for Solar, RV, Camping, and Backup Power This 12V 300Ah RV lithium battery fits a wide range of applications. For solar panels, it supports off-grid systems up to 61.44kWh. RV travelers can power essentials like air conditioners, cookers, refrigerators, fans, and lighting with its 3,840Wh capacity. It’s also great for camping and serves as a solid backup during power outages. Get Yours Today with Vatrer 300Ah Battery Ready to upgrade your energy storage?
