- BUILT TO LAST: Our 12V 100Ah LiFePO4 Batteries live more than 2000 cycles at 100%/8000 cycles at 50%(Suggested) depth of discharge, without decreasing in performance. The average lifetime of lead-acid batteries is about two years(500 cycles) at just 50% discharge. This basically means a LiFePO4 battery will last you at least 5 times longer than a lead-acid battery, which actually reduces overall cost. It has cold weather protection which is critical.
- AUTOMATIC BMS AND LOW TEMPERATURE CUT-OFF : The built-in Battery Management System (BMS) protects your battery from Over Charge and Discharge, Over Current, Short Circuiting, as well as Low and High Temperature for increased performance and longer life. The BMS will automatically cut off the battery and the voltage will drop below 1V. Only when the circuit is cut off, the battery will automatically reactivate after 1 second(No longer need a higher voltage input to activate). Besides, charging low temperature cut-off function will cut off the battery when the temperature below 32°F to ensure safe use and battery performance.
- LIGHTWEIGHT AND VERSATILE: Compared to lead-acid batteries, lithium provides greater energy density and are at least 1/2 the mass, it is a perfect upgrade for any 12V Deep Cycle battery, and best choice for many applications such as Fish Finders, Ice Fishing, Camping, Solar System, Home Alarm Systems, E-Scooters. Please charge the battery with a dedicated LITHIUM BATTERY CHARGER, and no more than 4 batteries in series or parallel.
