Tested to UL 1973 safety requirements for added confidence in battery safety and reliability.

• Cold-Weather Charging Without Bringing the Battery Indoors: This self-heating lithium battery automatically uses incoming charging power to warm the cells before charging in freezing conditions. It keeps winter RV and off-grid charging more practical without adding external heating pads.
• 3.84kWh of Energy for Longer Off-Grid Stays: The Vatrer 12V 300Ah LiFePO4 battery stores 3.84kWh of energy, giving RVs and remote cabins more usable power between charging sessions. Run daily essentials longer with less dependence on generators or shore power.
• Stronger Support for Inverter-Powered Loads: A built-in 200A BMS gives this RV lithium battery the current capability needed for demanding 12V systems. It provides more headroom for inverter appliances and multiple onboard loads running together.
• Battery Status at a Glance: Bluetooth monitoring lets you check charge level, voltage, current, temperature, and operating status directly from your phone. You get clear battery information without opening the battery compartment or relying on voltage alone.
• Recharge from the Power Sources You Already Use: Charge with a LiFePO4 charger, solar through an MPPT controller, or a vehicle-based DC-to-DC system. This flexibility makes the 12V 300Ah lithium battery easy to use across campground, travel, and remote-power setups.
• Expand When Your Off-Grid System Grows: The battery supports up to 4S4P configuration, allowing a single-battery setup to grow into a larger energy-storage bank. It gives your off-grid lithium battery system room to scale with future solar and inverter upgrades.
• More Years of Deep-Cycle Service: Rated for 4,000+ cycles, this deep cycle lithium battery is built for repeated daily charging and discharging. It reduces the replacement frequency and maintenance associated with traditional lead-acid batteries.
• More Installation Freedom in RV and Cabin Spaces: The battery can be installed in multiple orientations, making a high-capacity 300Ah battery easier to fit into existing storage bays and equipment cabinets. Its IP65-rated enclosure adds practical protection for RV and off-grid installations.

3.84kWh for Longer RV and Off-Grid Runtime

A refrigerator running overnight, lights after sunset, a water pump, fans, electronics, and other daily loads quickly add up when hookups are not available. This Vatrer 12V 300Ah LiFePO4 battery stores 3.84kWh of energy, giving you more room to stay comfortable between charging opportunities. Whether you are boondocking in an RV or running a remote cabin, the larger battery reserve helps reduce your reliance on generator time or the next available power source.

200A BMS Power for High-Demand 12V Loads

Turn on a coffee maker while your refrigerator, lights, and water pump are already in use, and current demand rises quickly. The built-in 200A BMS supports up to 2,560W of continuous output, giving this RV lithium battery the headroom for higher-demand 12V systems and inverter-powered appliances.

Flexible Charging at Camp and on the Road

At a campground, you can recharge with a LiFePO4 battery charger. While boondocking, solar panels and an MPPT controller can keep energy coming in during the day. On travel days, a DC-to-DC charging setup can use vehicle power to recharge your Vatrer 12V 300Ah lithium battery while you drive.

Battery Status on Your Phone

Before turning in for the night, you can see how much battery capacity is left without opening the RV battery compartment. Bluetooth monitoring through the Vatrer app shows state of charge, voltage, current, temperature, and operating status on your phone. You can see how the battery responds to active loads and decide whether to recharge the next day or adjust overnight power use.
