Hello,
I am currently in the process of building my own Bluetooth speaker. I want to make it run on 18650 batteries that can be recharged when low.
I have built a circuit but am running into an issue.
I have 4 18650 batteries hooked up in parallel. The output from these batteries then feeds into a TP4056 board for recharging and battery protection. The output leads of the TP4056 board then feed into 2 voltage step-up modules. One that increases the 3.7v to 8v for the Bluetooth receiver module, and another that increases the 3.7v to 12v for the speaker amplifier that I have.
The only issue is that when I turn on the amp, it is powered for about half a second and then turns off. The output from the batteries then is only able to provide about 1.5v until I pull them out of their battery holder and reseat them (breaking and reconnecting the circuit).
I have disconnected the Bluetooth receiver and tested the amp alone to make sure that the receiver was not drawing too much current, but it still yields the same results.
Does anyone have any ideas about how I can fix this?
Thank you in advance
