Of course not. The charge and discharge curves of lead-acid and lithium batteries are completely different, and the characteristics of the batteries are also completely different, so they cannot be used together. Because after mixing the group, after charging and discharging, the lead acid battery will change faster than the lithium battery cell voltage, so there will be a voltage difference in the group, forming a loop current. One guy becomes the burden. on the other, and the battery internal resistance is very low and the battery plates will start to be damaged after charging with a large current. While this process is quick, it only takes a few minutes; if it is slow, it only takes ten and a half days.
By the way, even batteries of the same type must be of the same model and manufacturer, preferably from the same batch and have the same operating experience.storage and transportation, so that the life of the assembly is as long as possible. .
