A, electric vehicle lithium iron battery can not be charged with the pulse charger of lead-acid battery. Because if the voltage is consistent, the lithium battery can be charged with lead-acid batteries, lead-acid batteries can not be charged with lithium, because the lithium battery pack has higher safety requirements. Because the lead-acid battery charger is generally set to a two-stage or three-stage charging mode, the 48V lithium iron phosphate battery pack does not match the voltage level of the lead-acid battery.
No way. Short time emergency use should also pay attention to observation. Lithium battery charger is constant voltage and constant current.
