Li18-12, 12v 18Ah Lithium Iron Phosphate, LiFePO4 High Capacity Deep Cycle Battery, Charger Included.

Lithium Iron Phosphate, LiFePO4 is changing the face of battery technology.They offer high rates of discharge, long life cycles and are the safest lithium battery chemistry available. Long cycle life up to 2000 recycles, 8 times that of lead acid battery, 3 times that of Ni-MH battery. Inherently safe, there's no danger even if the battery is misused. light weight upto 1/3 of lead acid battery, 2/3 of Ni-MH battery. Small volume of less than half of lead acid battery, smaller than Ni-MH battery. Low self-discharge, less than 5% after 6 months, good performance at high temperature, more than 70% capacitance remain after 1000 cycles at 45°C. It is environment friendly with no heavy metals or toxic material.
