Experience Unparalleled Power - Weize 12V 300Ah LiFePO4 Batteries!
Designed to conquer the test of time, our 12V 300Ah LiFePO4 Batteries redefine endurance, delivering over 2000 cycles at 100% discharge or an astounding 8000 cycles at 50% depth of discharge (Suggested) - all without compromising performance. Witness the difference as a LiFePO4 battery lasts at least 5 times longer than lead-acid counterparts, translating to significant cost savings. With cold weather protection as a critical feature, you can trust our batteries to thrive even in the harshest conditions.
Effortless Power Management - Welcome to the Future:
Embrace the convenience of an Automatic Battery Management System (BMS) that shields your battery from Over Charge, Discharge, Over Current, and Short-Circuiting. Low and High-Temperature protection ensures peak performance and prolonged life for your battery. Experience seamless power management as the BMS automatically cuts off the battery, with reactivation requiring just 1 second without the need for higher voltage input.
Unleash the Possibilities - Lightweight and Versatile:
Discover the potential of lithium's greater energy density, weighing at least 1/2 less than lead-acid batteries. The perfect upgrade for any 12V Deep Cycle battery, our LiFePO4 battery is the best choice for an array of applications. From Fish Finders to Ice Fishing, Camping to Solar Systems, Home Alarm Systems, and E-Scooters - you name it, our battery powers it all. For optimal performance, remember to charge the battery with a dedicated LITHIUM BATTERY CHARGER and avoid connecting more than 4 batteries in series or parallel.
