8kg.
The average energy density of this type of battery is approximately 120wh/kg 12v80ah=960wh 960/120=8kg.
The full name of lithium iron phosphate battery is lithium iron phosphate lithium ion battery. This name is too long, so it is called lithium iron phosphate battery. Because its performance is particularly suitable for power applications, the word "power" is added to the name, that is, lithium iron phosphate power battery. Some people also call it "lithium iron (LiFe) battery."
Lithium iron phosphate battery refers to a lithium-ion battery that uses lithium iron phosphate as the cathode material. The cathode material of lithium-ion batteries. mainly includes lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium oxide andcobalt is the cathode material currently used in most lithium-ion batteries
