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 Charger 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).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 2 batteries in parallel.SAFE AND ENVIRONMENTALLY FRIEDNLY: Made from 100% safe, nontoxic, not hazardous energy, Weize LiFePO4 battery has higher chemical stability, it is not prone to thermal runaway and will not overheat or catch on fire even if punctured. With no acid in the battery, you're able to safely mount in any position. BUT please read the matters needing attention carefully before using. Package:1x  20Ah LiFePO4 Batteries  PaymentDelivery detailsReturn PolicyAbout usWarranty PolicyPayment 1.We accept payment via PayPal, Visa, Mastercard, Apple Pay, Google Pay etc.
