- BUILT TO LAST: Our 12V 50Ah 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.
- AUTOMATIC BMS AND MAINTENANCE-FREE: 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).
