Review on HiLetgo ESP32 WiFi Bluetooth 🔌 Board Module - Dual Core, ESP-WROOM-32 CPU by John Murphy

works great so far! However, make sure your cables are properly connected to the battery connector. If the red wire doesn't look like it fits the small + sign on the circuit board and the black wire doesn't look like it fits the small - sign on the circuit board, you may need to rewire the wires in the battery connector follows exchange I did. did. This can be done with patience and a needle, utility knife, razor blade, etc. If you don't get it right, you will likely fry the board.
