I have a 24V audio amplifier that is powered by 8 packs of 6x protected 18650 batteries connected in series to produce 24V, and then all the packs are connected in parallel.
The amplifier powers a subwoofer and a pair of speakers. The issue was that when subwoofer kicks a deep note, the system just cuts out.
I introduced 2x47000uf capacitors to the circuit in parallel. Problem I have now, is that the batteries just shut down. I tried it with just one capacitor, and then it worked.
I'm guessing the capacitors drain the batteries too fast and they just switch off.
Is there anything I can add to the circuit to prevent this? Perhaps a resistor? What rating?
