dear
I have tried the connection method as shown in the figure below, but it seems not feasible during the test. There will be a current when a certain battery is connected forward and then connected backward.And it looks like if the two batteries have the same voltage, the diode will shut off the output.Want to ask to have correct usage method, best can apply 2, 3, 4 batteries at the same time
any advise？ thanks in advance~
