Vatrer 12V 300Ah Self-Heating Lithium Battery with Bluetooth and 200A BMS - 10 PACK

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.
