A:
LISHEN HESS only uses Lithium Iron Phosphate cells because these are much safer than the lithium batteries used in cars, for example. The chemical composition of the battery cells makes overheating due to so-called thermal runaway virtually impossible. This makes the cells safe and non-flammable even in extreme conditions. Lithium Iron Phosphate cells also have a very good life span. They are slightly heavier and less compact, but this is usually not a problem in a domestic situation. One more advantage is that the Lithium Iron Phosphate cells do not contain any cobalt, and they are true cobalt-free batteries, which is more economic and environment friendly.
