Power Queen 12V 300Ah Lithium Battery: Ready for Any Challenge
We are excited to introduce our Power Queen 12V 300Ah lithium battery, designed for reliable power storage across various applications. Ideal for home storage, RVs, marine, off-grid systems, UPS, and trolling motors, this robust battery ensures long-lasting performance and security in all conditions.
One Powerful Battery, Fewer Connections, More Space
Ditch the mess of multiple batteries. The Power Queen 12.8V 300Ah LiFePO₄ gives you the same capacity as three 100Ah units — with up to 27% less space and far fewer connections. Smarter design, easier setup, and more room where it matters.
Superior to Lead-Acid Batteries
Power Queen 12V 300Ah lithium battery offers double the energy capacity of traditional lead-acid batteries. Compared to a 12V 300Ah lead-acid battery, Power Queen's lithium battery is 1/3 lighter and provides 2X the energy density.
Advanced Self-Developed BMS for Optimal Safety
The Power Queen 12V 300Ah battery comes with a reinforced 200A BMS for optimal performance and protection. It offers over 20 safety features, including protections against overcharging, over-discharging, over-current, short circuits, high temperatures. A 30-second self-recovery feature also ensures long-term reliability.
From Coffee Maker to AC — All At Once
With 200A continuous current, 800A peak, and 2560W output, the Power Queen 12.8V 300Ah LiFePO₄ battery handles all your appliances at the same time — from kitchen to climate control. Perfect for RVs, off-grid life, and high-demand setups.
