So for my portable, I am using two 3.7v batteries in a series to achieve 7.4v to power my portable. Although, the only way I can charge my batteries together is if I put them in parallel and then connect them to the charger. I was planning on having a switch on the outside to switch the batteries from series to parallel. The switch I already have (and would like to use if possible) is a SPST (single pole single throw) switch. Would anyone know how to wire this switch to change the batteries from series to parallel?
Make an easy parallel to series switch?

Here is a circuit I designed for my portable for just the occasion:
sorry its a little rough; its one of my first circuit diagrams. You would need either 2 SPDT switches or 1 DPDT switch (or 4 SPST switches
). The circuit I have also disconnects the components (screen, console, speakers) from the battery. You might be able to do what ur trying to do with a SPDT if you're creative, but it won't disconnect from the components (that might be a safety hazard depending on your batteries)
