Vatrer 12V 300Ah Self-heating Lithium Battery 300A BMS with Cooling Fan

If you're searching for a dependable energy solution to power your RV, solar setup, or home backup system, the Vatrer 12V 300Ah heated lithium battery with its 300A BMS and cooling fan might be just what you need. This 300Ah self-heating 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, it can meet your usage needs.

Long-lasting Performance with Smart Safety Features

This Vatrer 300Ah battery is built to last, offering over 5,000 charge cycles and a lifespan exceeding 10 years. That means you can rely on it for years without frequent replacements. The heart of its durability lies in the built-in 300A Smart BMS, which includes advanced safety features like protection against over-charge, over-discharge, over-current, short circuits, and temperature extremes. The high-temperature cutoff kicks in if things get too warm, while the low-temperature cutoff 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 (46°C) and turns off below 111.2°F (44°C), 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 heated 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 (0°C) as long as the charging current exceeds 10A. The process is straightforward: the BMS detects the cold, triggers an internal heating film to warm the cells, and stops at 41°F (5°C) to switch to normal charging. This makes it ideal for cold climates where traditional batteries might fail. Complementing this, the active cooling fan steps in to manage heat, providing a balanced temperature control that keeps the battery running smoothly and safely.

Smart Monitoring with Bluetooth Connectivity

Stay in control with the Vatrer 300Ah battery's Smart Bluetooth 5.0 feature. This allows you to connect to the Vatrer app on your phone for real-time insights. You'll see details like battery percentage, remaining capacity, voltage, current, power, individual cell voltages, temperature, and cycle count. The app also lets you 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 want to keep tabs on energy solutions without guesswork.

Powerful Energy Output

This 12V 300Ah heated 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.

Expand Your Power with Flexible Capacity

Need more power? The Vatrer 300Ah battery supports expansion with ease. You can link up to 4 units in series to reach 48V (51.2V), ideal for advanced solar or inverter setups, or connect up to 10 in parallel for a massive 3,000Ah capacity, scaling the max usable energy to 38,400Wh. This flexibility ensures you can tailor a reliable power system as your needs grow, whether you have a large RV or a complete home energy solution.

Flexible Charging Options

You can charge the Vatrer 300Ah battery in multiple ways to suit your setup. A LiFePO4 AC charger (14.6V 40A) takes about 7.5 hours, a solar panel with an MPPT controller (like 850W) can do it in 4-5 hours per day, and a generator with a 40A DC-to-DC charger also takes about 7.5 hours, offering flexibility for solar panels or generator use.

Compact Design and Portability Durable

The Vatrer 300Ah battery is designed with practicality in mind, measuring 15.51 x 8.27 x 11.69 inches and weighing 71.65 lbs. Its built-in handle makes it easy to move, while the secure M8 terminal bolts (16mm length, 8mm diameter) ensure a stable installation, perfect for RV or home setups. With an IP65 waterproof rating, the Vatrer 300Ah battery stands up to tough weather conditions. Its sturdy SPCC metal casing is easy to disassemble for maintenance or upgrades, and its zero-maintenance design is built with the environment in mind, reducing waste over its long lifespan.

Perfect for Solar, RV, Camping, and Backup Power

This 300Ah self-heating battery fits a range of applications. For solar panels, it supports off-grid systems, reaching a total of 61.44kWh. This scalability extends the max usable energy to 38,400Wh, perfect for larger setups. RV travelers can power essentials like air conditioners for 3.84 hours, cookers for 5.48 hours, refrigerators for 12.8 hours, fans for 38.4 hours, or desk lamps for up to 384 hours with its 3,840Wh capacity. It's also great for camping, offering reliable power in the wild, and serves as a solid backup during power outages at home. The flexible design adapts to your growing energy needs, making it a versatile choice.
