Lithium Iron Phosphate (LiFePO4) is extremely stable lithium chemistry when compared to almost all other lithium chemistries. The battery is assembled with a naturally safe cathode material (iron phosphate). Compared to other lithium chemistries iron phosphate promotes a strong molecular bond, which withstands extreme charging conditions, prolongs cycle life, and maintains chemical integrity over many cycles. This is what gives these batteries their great thermal stability, long cycle life, and tolerance to abuse. LiFePO4 battery is not prone to overheat, nor is it disposed to "thermal runaway" and therefore do not over-heat or ignite when subjected to rigorous mishandling or harsh environmental conditions.
