Wifi 32 Lora V2

Hello All,
I am new on this forum and would like to ask a question about Heltec Wifi 32 Lora V2 board.

When i connect the battery to the board then the board does not turn on. But with the USB everything working fine.

I have been searching on net and reading the schematic as well and found that every board is Charging IC TP4054 or MCP chip but in my board i did not find any chip. Would you please point me out where is it ?

Also, when i connect the board with the USB then the Battery LED is SOLID means it is charging but it does not OFF.

I hope to receive a positive reply here.


This is Charging chip.
