## Overview

This 2A 5V Charge Discharge Integrated Module combines charging, discharging, lithium battery protection, and battery level indication in a compact 6-pack. Designed for microcontroller compatibility, it features robust safety protections (OCP, OVP, SCP, OTP), smart load-triggered output control, and supports simultaneous charge and discharge at a stable 5V output. Ideal for powering portable electronics, car retrofits, and DIY projects, it balances efficiency with safety in a sleek, small form factor.

Review: Great for some but not for all. - The bad: It says 2.1A output current but I tested two of them and got ~250mA and other things you might not like is the four LEDs are on while charging and discharging (not good for low power circuits but good for showing remaining power) and the output is on (with no way to turn off) while charging. The good: The output voltage is a solid 5V and while pulling the max I got of ~250mA the voltage only dropped to 4.89V. You can take all the LEDs off without affecting the circuit or just leave the one "100%" marked one and it'll only turn on when fully charged. The form factor is great and the gold contacts are cool. TLDR: Not the best for higher current projects 250mA+ or low current projects under ~5mA! All numbers were my results, yours may differ. I like it.
Review: Well made - These look nice, but I really wish it was easier to use the 5V output. Sending a signal every 5 seconds with a micro controller is a pain. I mostly just would love to find a module that can charge a lithium ion battery over micro-USB and have it also have a built in 5V regulator too. I know the Adafruit Powerboost does that, but they cost $15-$20 each. This device is so close to doing that. Edit: I found out why I had to keep activating this module to keep the power output on. This module auto detects current draw. If it is high enough it will keep the 5V output on. I was trying to keep an Arduino in a low power state then occasionally waking it up to transmit a radio signal which can draw a lot of power for a few seconds. My current draw on the Arduino was way too low so this module would shut itself off. The only way to keep it on was to send the button input on the board a low signal every so often to prevent it from turning off. I couldn’t find any detailed information on these modules, but I figured these out when I tried using them again for a portable LED project. When I woke up the module and the brightness on my LED board was high it would stay on indefinitely. If my brightness was low when it first woke up it would shut off by itself after 30-45 seconds. If it woke up on high brightness and I switched it down to low without restarting it then it would still stay on indefinitely. Kind of odd behavior, but now that I understand these modules these are great for many use cases. I love how the push button on the side acts as a power switch. Press once to wake it up and press it twice to turn it off.

## Features

- ★ MCU users, if you accept a small load KEY can be connected to the microcontroller about 20s to provide a low level allows the module to continue working. Trigger mode: low level trigger (ground)
- ★ 4 in 1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection
- ★ In discharge mode (The charging mode KEY function is invalid), trigger the KEY port once to open the output; continuously trigger the KEY port twice to close the output
- ★ The first time the load is connected, the output is automatically turned on. If the load is less than 50mA, the output will be automatically turned off after 30 seconds; if the load is greater than 50mA, the output will be automatically turned on
- ★ Allow discharge while charging. (Note: At this time output voltage 4.7 / 5V)

### ⭐⭐⭐⭐ High s
*by N***X on March 17, 2021*

I really would give this a 5 because it is an incredible little board. Being able to power 5 volt devices from single cell lipos and have a charged circuitry in one board is pretty great. But I have found that the self discharge rate is just too high. Every time I go to grab my battery powered devices the battery is dead. So now I actually have to add a power switch online with the battery, which adds a whole layer of complication. If the self discharge rate were slower, I would give this five stars.
