The protection board is 32V20 45A 64V series, which is equivalent to the rated 60V lead-acid battery. The protection board is suitable for lithium iron phosphate batteries and has a balanced charging function. The battery cannot be 45A, or it can be used even if the protection board is not connected to 20 strings, so the voltage may be changed. 20 strings of 32 V make 64 V, not 48 V; 16 strings are 512V, a lithium battery rated at 48V, with a full voltage of 576V, which is equivalent to a lead-acid battery with a 48V rated full voltage of 576V. There are also 15 strings of 32 V = 48 V nominal 48 V, fully charged 540 V.

Generally speaking, recycling of waste lithium-ion batteries is a combination of physical and chemical means. The physical means mainly include the processes of mechanical separation, de thermal, mechanochemistry and dissolution treatment; Among chemical means, due to the advantages of low energy consumption, minimum waste water and high recovery rate of high purity metal, most researchers tend to use the hydrometallurgy to recycle. LIB waste mainly includes acid/alkali/biological filtration, chemical precipitation, solvent extraction and electrochemical processes, etc.
