Beetle BLE and Micro Lipo USB charger

Hello, Would it be possible to use the Micro Lipo USB charger (DFR0667) with the Beetle BLE (DFR0339) and a 3.7V LiPo battery at the same time?

I am trying to create a simple bracelet type DIY device which will have 2 vibration motors connected to the Beetle BLE. I want to use the LiPo USB charger so that I don't have to disassemble the bracelet & disconnect the battery every time I have to charge the battery.

So I am planning to connect the 3.7V LiPo battery to the LiPo charger as well as the VIN on the Beetle BLE. Will this work, or should I try using another charger board / BLE board?

Thank you for your support and advice!

Do you want to connect the power supply of the charging board to the main control by means of flying wires? I don't think this is a good idea. When the charging board and the battery supply power to the motherboard at the same time, some circuit problems will occur.
