Why use protective plates for lithium iron phosphate battery packs?
Jul 29 , 2021
The protection of lithium iron phosphate batteries is determined by its own characteristics. Because the material of the lithium-ion battery itself determines that it cannot be overcharged, over-discharged, over-current, short-circuited, and ultra-high temperature charging and discharging, the lithium-ion battery package will always appear with an exquisite protection board and a current fuse. The...
