I am making a battery and AC powered amplifier speaker. I'm stuck on this part of the circuit, pardon my horrific schematic.
I have a battery protection circuit to control the over under charge on the 18650 li-ion batteries. Then I have a Smart charger that will control the voltage to charge the batteries.
Here is the smart charger and PCM Iordered.

Both the charger and the AMP will be powered by a 12v power supply.
What I don't want is 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?
Even if that works how do I keep the power from the smart charger from powering the AMP?
Do I need a switch of some kind? either a relay of some kind or manual switch?
