Help with Bluetooth speaker kit troubleshooting wireless charging issue

Job ID: 40319276

Budget: $15 – $25 USD

We have developed a Bluetooth speaker kit for students to assemble. The kit consists of a Bluetooth speaker module with one 3.7V Li-ion rechargeable battery. This is charged through a USB battery charger board.

We have added the ability to wireless charge the battery by adding a second charger board along with a wireless receiver pad. This works well.

We are using a Quickcharge QC3.0 mains power supply with QC wireless transmitter pad. The issue we are having is the wireless transmitter pad is becoming very hot and we thought that there may need to be s voltage regulator on the battery side to work with the wireless charger.

We are wanting to find a solution to this issue with the wireless charging becoming very hot while charging.
