Blocking/Bypass Diodes in Battery Circuit Help//

[prototypingfool]

In the attached schematic i'm trying confirm my blocking diodes are located in the right position, and if i need resistors as well.

Design goal is to put a circuit in (using diodes) that will assure the batteries dont charge each other AND if one battery goes bad, the entire system wont shut down. Can i use bypass diodes as well?
Each battery has two cells for a total of 30 volts. These are standard BA-BB-5590 types.

Thanks in advance for the help.

How are the batteries getting charged?

-Batteries are not getting charged. Plan is to install them till they run out of juice, or run off of the VCC port when something is plugged in...

Just found this on a google search as well

-is too complicated? Would love to just use simple diodes...

thx in advance!
