I'm working on a battery and AC-powered amplifier speaker. I do have a battery protection circuit to control the over-under charge on the lithium ion battery. Then I have a smart charger that will control the voltage to charge the batteries.

Anyone worked with something like this before?
 
I just don't want the 12v PS to power the PCM directly. Could I do this with diodes between the AMP and the PCM, I would also need them between the AMP and the smart charger?
