Charging a 18650 battery pack?
Hi. I am working on a Bluetooth speaker for home and the amplifier I am using requires a 12V supply. I am using a 3S 18650 battery pack as the 12(ish) volt supply. However I am struggling to find anything online that is a suitable charging circuit to wire in with the 3S 18650 battery pack? Everything online seems suitable for a 2 or 4S battery pack but there doesn’t seem to be anything for a 3S one. Is there anything I can do to charge this or will I have to change the battery for something more simple? Cheers!

And if you are trying to build the battery pack out of 3 separate cells, be sure to include a battery management system.

apparently this is a 10.8V 2.6Ah (28Wh, 0.5A rate) with built in 12 volt regulator.
