Comparison between LiFePO4 battery and Lead-Acid battery:
BatteryIngredientsLiFePO4 BatteryLead-Acid 
Safety & Environmental ConcernSafest; no explosion; no smoke; no fire under very bad working condition; most environmentally friendly; non-toxic; no rare metal, fire resistant, easily disposed of.safety is acceptable; heavy pollution to water and soil; breaking ecological balance; threatening people' s health especially for Children; hard to dispose of; high re-use cost.
Life CycleBest, up to 1000 times under 80% DOD(theoretically 2000 times)  Very short life cycle, about 150 times under 100% DOD; maintenance needed very often.
Long term CostMost economicalCost of whole lifetime is higher than  LiFePO4
Thermal PerformanceExcellent – Can work normally under -20° C~70° CThe capacity decays quickly if the temperature is higher than 50° C
