Low power solution for ESP32 with Lipo battery June 2, 2021 June 3, 2021 colin Home Blog Low power solution for ESP32 with Lipo battery I want to develop an IOT product with ESP32 MCU, it should with 18650 Lipo battery, and the battery life should be as long as possible. After study current solutions, I found most of them have some problems. Before go further, let’s check 18650 discharge characteristics first. 18650 Battery Discharge Curve. Source: batteryuniversity.com If discharged at 0.2C, at the discharge cutoff of 3.0V/cell, produces only about 3200mAh. Most of product use ESP32 module,  ESP32-WROOM-32D . It work voltage rang is: 3.0 V ~ 3.6 V. Current min 500mA. ESP32-DevKit-LiPo ESP32-DevKit-LiPo Github link .  Feature: ESP module: ESP32-WROOM-32D With USB input, changer and program. External 5V input. USB, Battery power path choose. USB to URT with CH340T. Battery IC BL4054B-42TPRN(SOT23-5). Charge current 455mA. Power to ESP32 with SY8089AAAC. It’s a 5.5V, 2A continuous, 3A pe
