Interesting….I did more research. The general opinion is that it’s fine. Here is a video experiment + measurements.
Apparently the lower internal resistance (higher capacity) battery will supply the most current while the lower capacity battery….now having higher internal resistance after running….will back off and supply the lesser amount of the total current.
Of course, the battery voltages are equal always.
The precaution is….The two batteries charged voltages should be close before connecting.
Learned something!!!! Anyone finding differently? There are folks like me that say don’t….but their comments are usually followed with a lot of discussion + reasons why it is OK.
