What Needs to Be Replaced When Switching from Lead-Acid to Lithium Batteries?
1 Answers
When switching from lead-acid to lithium batteries, you need to replace the charger and adjust the equipment matching parameters. Below are the differences between lead-acid and lithium batteries: Nominal voltage: The nominal voltage of a single lead-acid battery cell is 2.0V; for a lithium battery cell, it is 3.6V. Internal materials: The positive and negative electrodes of a lead-acid battery are lead oxide, metallic lead, and concentrated sulfuric acid electrolyte; for lithium batteries, they are lithium cobalt oxide, lithium iron phosphate, lithium manganese oxide, graphite, and organic electrolyte. Energy: Lead-acid batteries have 30WH/KG; lithium batteries have 150WH/KG. Electrical characteristics: Lead-acid batteries cannot discharge at high currents and have a short lifespan; lithium batteries can discharge at high currents and have a long lifespan.
