Features

  • 4 in 1 Charging + Discharging + Lithium Battery Protection + Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection.
  • 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)
  • 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)

    • Great Lithium Ion Charger
I use these to charge old batteries from Switch controllers for hobby projects. Make sure you install the battery last so you will be less likely to fry the circuit. I have fried a few. Use tape to cover the solder leads if you need to. The power plane pieces are very close and slightly difficult to solder. But with patience, you can do it! They also work with bigger batteries like this! https://www.amazon.com/gp/aw/d/B0B4DRZBWX?psc=1&ref=ppx_pop_mob_b_asin_title ... show more

    • Charges a 3.7V Lithium battery with a 5V input, and Boosts the 3.7V to a 5V output.

This is a nice little board. With 5V in, the board charges a 3.7V Lithium battery. When you remove the 5V input, the board boosts the 3.7V from the battery to a 5V output. Its a charger and a booster in one board. There is not a lot of info for this board, but it appears to be a clone of a IP5306, which I have included in the photos. The picture that is included on Amazon shows a 200mAh battery but I used it to charge my 5000mAh battery, which I also purchased on Amazon, awsome battery. It took 24hrs to fully charge my 5000mAh battery. The description says that you can charge and discharge at the same time, but I have not been able to get this to work. When I have 5V to the input pin, the output pin is low, or 0V. When I remove the 5V from the input, the output pin goes high, 5V. The only thing I can get the KEY pin to do is to shut the board down, whether charging or discharging, by holding it low, 0V, for 20 seconds. Also the push button on the board does the same thing, provides 0V to the KEY pin. My plan is to solder onto the LEDs and tie them into an Arduino and write a sketch to charge the battery if its below 25% and not in use. ... show more

    • Well buit.
This was just right for my use, i hooked up a battery pack to it and the out to a bluetooth board amp, and a usb c female connector on the in to charge battery when ever i need to. Its very small so i can stuff it out of the way as long as i can get to the on button.100% recomend.

    • Great 5V backup source for projects from 3.7V Lithium cell

I use these as a backup for Arduino/ESP and RPi projects where i want battery backup from a single cell Lithium 3.7V battery. If you're doing a cold start then you do have to press the key, but once you're project is live that isn't required and you don't need to access it again. I have fried one board by messing up with reversed polarity on the Vin side, but otherwise no issues. ... show more

    • Love these
Bought for one reason, yet these solved a completely different problem. Love that I can connect these to a battery, then connect to a device, and keep it topped up unattended. Saved me so much headache

    • Auto power off can't disable!
The unit shuts off on light loads. No way to disable the auto power off. Whoever made the feature a default, should be sacked. This is amateur hour.
