I am tinkering with a build using a previously wired Sherwood DS-N10 Bluetooth speaker and trying to convert it to a wireless speaker by connecting a power bank to the DC inputs on the board using a buck board. I have a Uniden power bank, model UN464 with a output of 5v or 1000ma and input of DC5v, total of 4000mah. Now I have this power pack array for three 18350 batteries so I took two of the batteries from the power bank and added a third battery in and connected it all to the USB input/ouput connector from the original power bank.My question is will the extra battery overload the circuit on the power bank or should it be okay? via /r/DIY https://ift.tt/2olsy9E
