JUST TRY IT! Our 12v 12ah LiFePO4 battery may have a tough exterior, but it is built to last and stand the test of time. Our batteries are known for their reliability in the power industry. Its high-current delivery capabilities and extended service life make it a reliable option for all your energy storage needs. The hardened ABS plastic external casing provides an extra layer of protection against spills and leaks. With a built-in BMS (Battery Management System), our LiFePO4 battery is protected from overcharging, over-discharging, over-current, and short-circuiting, as well as high-temperature cutoff, ensuring maximum safety and reliability. 100% SAFETY The built-in BMS protects the Goldenmate LiFePO4 battery from various risks like overcharging, over-discharge, over-current, overheating, and short-circuiting. It also features a high self-discharge rate that can maintain the battery's charge for up to one year of maintenance-free storage. Additionally, high and low-temperature protection safeguards the battery from damage. WHY CHOOSE GOLDENMATE 12V Lithium LiFePO4 Deep Cycle Battery? GOLDENMATE 12V battery pack has higher power, Longer cycle life, good safety performance, wider temperature range, and no memory effect, etc. GOLDENMATE 12V 12Ah lithium-ion battery can run 5000+ cycles, its lifespan can last up to 10 years, More than 10 times higher than lead-acid batteries (generally only 300-400 cycles can be charged). 3 CHARGING WAYS In addition to the ease of charging using the specified LiFePO4 battery charger, solar panel + MPPT, and generator, the 12V 12Ah LiFePO4 battery offers the advantage of a quick charge. This means that the battery can be fully charged in a shorter time than traditional batteries, which is particularly useful in emergencies or situations where time is limited. WIDELY USED Moreover, the battery's ability to accept a quick charge without damaging the battery or reducing its cycle life ensures that it is a reliable and efficient power source for a wide range of applications, including wheelchairs, emergency lighting, marine, golf carts, home energy storage, computer power backup, off-grid applications, solar panel wind energy storage solutions, among others.
