Disable battery management system on Wifi Lora 32 Board

#1

Hello,

i try to reduce the current during deep-sleep-mode. Its about 10mA. So I read that the battery management system needs a lot of current, but I cant found any code to disable them. Only to unsolder a mosfet on the board.

How can I disable the battery management system during the sleep-mode?

I am new in this forum and if you can help me I will much appreciate it.

hi,

I’m sorry that This is a hardware level change. According to our own test, the current at low power consumption is about 0.8 mA. Because the esp32 has an external flash, The system needs to maintain the normal operation of external flash. So,The minimum is 0.8 mA.
