More Energy for Every Trip
Power your RV, boat, or off-grid setup with the Vatrer 12V 300Ah Bluetooth lithium battery, a high-capacity 300Ah lithium battery built with 12.8V nominal voltage and 3,840Wh of usable energy. This 12V 300Ah lithium battery delivers 200A continuous discharge for demanding onboard equipment, while up to 1,500 CCA provides the starting power needed to turn over a compatible marine engine.


Reliable Starts Under Heavy Load
The built-in 200A BMS keeps your 300Ah lithium battery stable while appliances, inverters, and onboard systems draw continuous power. It also supports short bursts of up to 1,500 CCA, giving this Vatrer 12V 300Ah lithium battery the deep-cycle performance and starting capability expected from a marine starting battery. Protection against overcharging, overdischarging, overcurrent, short circuits, high temperatures, and low temperatures helps prevent unexpected shutdowns and battery damage.


Cold Weather Protection That Works
Freezing mornings should not put your battery at risk. This Vatrer 12V 300Ah LiFePO4 battery automatically stops charging below 32°F, cuts off discharging below -4°F, and resumes charging at 41°F. Whether you rely on a 300Ah lithium battery for winter RV trips or early fishing runs, you can avoid unsafe charging conditions and keep your system protected.


See Your Battery Status Instantly
Bluetooth monitoring lets you check voltage, current, temperature, state of charge, and operating status through the Vatrer app. With the Vatrer 12V 300Ah Bluetooth lithium battery, you can view real-time data from your RV, boat cabin, or off-grid shed instead of opening a compartment or relying on an unclear battery gauge.


Big Capacity Without the Bulk
At 55.23 lbs and 15.16 × 7.56 × 9.76 inches, this Vatrer 12V 300Ah lithium battery is easier to lift and install than a bank of heavy lead-acid batteries. The compact design of this 300Ah lithium battery fits into RV battery bays, boat compartments, campers, and solar cabinets while still delivering up to 3,840Wh of energy.


Grow Your Power System Over Time
Connect up to four batteries in series for a 51.2V 300Ah system or four in parallel for 12.8V 1,200Ah. Expanding with multiple 12V 300Ah LiFePO4 battery units allows a full 4P4S configuration of up to 61.44kWh, giving your 300Ah lithium battery setup room to grow for RV solar systems, off-grid cabins, mobile workshops, or backup power.


Spend Less Time Waiting to Recharge
A compatible 14.6V 70A LiFePO4 charger can recharge this Vatrer 12V 300Ah lithium battery in approximately 4.5 hours. You can also charge your 300Ah lithium battery using solar panels with an MPPT controller or through a properly configured generator or DC-DC system, whether at home, at the marina, or off-grid.


Keep Everyday Equipment Running Longer
The 3,840Wh capacity of this 300Ah lithium battery provides up to 38.4 hours for a 100W fan, 12.8 hours for a 300W refrigerator load, 7.6 hours for a 500W cooker, or 2.5 hours for a 1,500W air conditioner. This 12V 300Ah Bluetooth lithium battery gives you more freedom to run essential appliances without constantly checking remaining power.


Make the Upgrade Before Your Next Trip
An aging lead-acid battery can leave you planning every trip around limited runtime, slow charging, and uncertain starts. Upgrade to the Vatrer 12V 300Ah Bluetooth lithium battery now so your next drive, fishing morning, or off-grid stay begins with dependable power already in place.


Tech Specs
FAQs
Yes, if your engine runs on a 12V system, supports a LiFePO4 starting battery, and requires up to 1,500 CCA. Always check your engine manual for minimum CCA requirements. The starter only pulls the current it needs, so this 12V 300Ah lithium battery with 1500 CCA will not overload a compatible engine.
Yes. This dual-purpose 300Ah lithium battery can handle both house loads and engine starting in a properly configured 12V system. Keep at least 20%–30% charge reserved for starting, and avoid running high-power appliances during engine cranking for stable performance.
Yes, but only with proper setup. Use a DC-DC charger or a regulated alternator system that outputs 14.2V–14.6V. Direct alternator connection without regulation can cause overheating or voltage spikes. A DC-DC charger ensures safe charging for your 12V 300Ah LiFePO4 battery.
Only if the charger has a LiFePO4 mode and outputs 14.2V–14.6V. Disable equalization and desulfation modes, as they use higher voltages designed for lead-acid batteries and can damage a 300Ah lithium battery.
A 2,000W inverter is ideal for this battery’s 200A continuous output. At 12.8V and 90% efficiency, it draws about 174A. A 2,500W inverter can exceed 217A and may trigger BMS protection. Always consider startup surge when powering appliances like air conditioners or refrigerators.
For high-current setups near 200A, use 2/0 AWG marine-grade copper cable. Increase cable size for longer runs to reduce voltage drop. Install a Class T fuse within 7 inches of the battery’s positive terminal to protect your 12V 300Ah lithium battery system.
No. Do not connect this Vatrer 12V 300Ah Bluetooth lithium battery in series or parallel with AGM, gel, or flooded batteries. Mixing battery types can cause imbalance and damage. Use a DC-DC charger or isolator if both battery types are in the same system.
The battery has an IP65 rating, meaning it resists dust and water spray but is not submersible. Install it above the bilge in a dry, ventilated area. Avoid exposure to standing water or extreme engine heat to protect your marine lithium battery.
Disconnect all loads and chargers before storage. Keep the battery at 40%–60% charge and check it every 1–3 months. Store it in a dry space between 32°F and 77°F with humidity below 60%. Avoid storing it fully discharged to maintain battery health.
No. The Vatrer app connects directly via Bluetooth, so no WiFi or cellular signal is required. You can monitor voltage, current, and battery status locally. Keep your phone within Bluetooth range, as metal enclosures may reduce signal strength.
