Hi, I'm planning to build a DIY speaker. I'm not that knowledgeable in electronics so I'm having doubts if I can connect my XY-P15W(DC8-24V) bluetooth module and TPA3110 30W+30W(DC8-26V) amplifier module to 4 18650 batteries connected in series with BMS. Can someone help me how to connect them properly? And using the same power source will cause issue to either of the circuit?
