Assembly of a 5 + 5 watt stereo Bluetooth audio amplifier. Starting from the CT14 module of ICStation, a wireless stereo amplifier is built. The amplifier is powered by a high capacity Li-ion battery. The charging module with TP4056 protection is mounted to charge the battery, and a pair of recycled speakers are used. The whole set is assembled in a custom made wooden box. A support made of PLA is also built to mount the two PCBs and the battery inside the box.

You do realize that the CT14 module, has a charger IC ON that module...you don't need the other charger plugin as well

Cool design

The problem is that the charging circuit of this module (CT14) doesn't control anything, barely limits the current and doesn't protect the battery. If you use it, the life of the battery is shortened.

Didn't know that...good to know...thanks!
