About This 【3.84kWh USABLE ENERGY & LONGER PERFORMANCE】A full charge on Power Queen 12.8V 300Ah LiFePO4 Battery can support 3.84kWh energy for 90% appliances, like running a 200W h eater mat nonstop for 19 hours in winter. This lithium battery has a great 300Ah capacity with a low self-discharge rate, the depth of discharge of our battery is about 100%, which provide 40% more usable power than the 300Ah lead-acid battery. If you want a satisfied big power, this battery would be your best choice! 【200A BMS WITH 2560W MAX. LOAD POWER】Power Queen 300Ah Lithium Battery has built-in 200A BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit. Our battery has 12 cells inside, the auto motive grade cells are high-density and stable, it’s safe when used in our daily life and friendly for the environment. And 2.56kW Max. Load Power would allow us to connect more common applications simultaneously to enjoy a more convenient life. 【DOUBLE STORAGE CAPACITY FOR THE SAME FOOTPRINT】If you were planning on being off-grid quite a bit, installed lead-acid batteries just weren’t enough. Because the lead-acid battery is too heavy to move. And it can only discharge 60% of energy when you use multi applications. Our 12.8V 300Ah LiFePO4 battery has more than double storage capacity for the same footprint compared with a lead-acid battery. Our 12.8V 300Ah Lithium Battery is a great replacement of lead-acid battery! 【MAX. 61.44kWh ENERGY STORAGE SOLUTIONS】Power Queen 12.8V 300Ah LiFePO4 Batteries support up to 4 in parallel and 4 in series (Max. 4P4S) to get more capacity (600Ah, 900Ah, Max.1200Ah) and higher voltage (25.6V, 38.4V, Max.51.2V). Max connected in 16 batteries (Max. 4P4S) to get a 51.2V 1200Ah battery system, with 61.44kWh energy. This powerful storage solution could be widely used for the home solar system, emergency backup power system, and yachts trip. 【Warm Tips】① This Battery is an energy storage battery rather than a start-up battery, we do not advise using it to start engines or golf carts. ② If OT terminals are attached directly with screws and their thickness is less than 2mm, please add gaskets to ensure secure attachment and prevent loosening or overheating. The same precaution applies when using clamps Overview Brand : power queen Size : 12.8V300Ah Number Of Cells : 8 Terminal : M8 Automotive Fit Type : Universal Fit Manufacturer : Power Queen Vehicle Service Type Boat, Marine, MotorHome, RV, Solar energy System, Travel Trailer, Yatch, campervan, home back energy Boat, Marine, MotorHome, RV, Solar energy System, Travel Trailer, Yatch, campervan, home back energy See more : Voltage 12.8 Volts : Vehicle Service Type Boat, Marine, MotorHome, RV, Solar energy System, Travel Trailer, Yatch, campervan, home back energy Boat, Marine, MotorHome, RV, Solar energy System, Travel Trailer, Yatch, campervan, home back energy See more : Voltage 12.8 Volts Battery Cell Composition Lithium-Phosphate : Item Weight 29 Kilograms : Battery Cell Composition Lithium-Phosphate : Item Weight 29 Kilograms Show more
