Logistics - the lithium battery is small in size, light in weight and easy to transport. Fast charging - lithium batteries charge and recharge much faster than lead-acid batteries. Maintenance free - lithium batteries do not require any maintenance to ensure their performance. High efficiency - lithium batteries offer reliable, stable, long-lasting power. Their energy density is higher, which means they have high power capacity. Cycle life - more than 2000 times - lithium batteries are generally smaller and lighter in weight. This is a big advantage which helps its application in various portable consumer electronic devices. Read more lifepo4 batteries have a life span 10 times longer than that of traditional lead acid batteries. This dramatically reduces the need for battery changes. Lithium iron phosphate batteries operate with much lower resistance and consequently recharge at a faster rate. Lifep04 lightweight batteries are lighter than lead acid batteries, usually weighing about 1 or 4 less. Lifep04 provides twice the battery capacity in the same amount of space. With operating ranges from -40 to 158 degrees fahrenheit, lifepo4 batteries handle far wider variations in temperature. Lithium iron phosphate batteries are safe for use in any system. Other advantages of lifep04 technology include upper and lower voltage protection, dead short and reverse polarity protection, and a flame-retardant chemistry.
