## Description

Module for quickly creating a powerbank on 3.7V Li-Ion, polymer, 18650 or 21700 batteries in parallel, offers bidirectional charging and discharging via USB-C and USB output, with total power up to 22.5W. It automatically supports PD2.0 PD3.0, PPS and QC for fast charging, has a digital display and LED for level, includes complete protections and a thermal sensor for battery safety.
Fast charging powerbank module, designed for 3.7V lithium batteries, including polymer, 18650 and 21700 types, which allows the creation of a powerbank with the ability to provide a total output power of 22.5W via QC (Quick Charge) and PD (Power Delivery) 2.0 and 3.0.
It is used together with a lithium battery (or several in PARALLEL ), offering the possibility of charging and discharging via the Type-C port or only discharging via the USB 2.0. DO NOT connect the batteries in series!
This module allows efficient and protected charging of batteries, ensuring their safety against overvoltage, short circuits and excessive charging. The module is equipped with a thermistor that is placed on the battery and provides temperature protection in case the battery overheats.
There is also overcapacity protection, through two resistors (see details below).
It has an LED indicator and digital display for monitoring the charge and a button to activate the display.
Protocols are detected automatically, depending on the loaded device.

Dimensions mm: 33 x 28mm
Use:
Use thick and short cables, capable of supporting a current of 10A.
Connections must be soldered, not just twisted, to avoid energy losses, increased resistance, and imperfect contacts.
Batteries can only be connected in parallel (the number of batteries is not limited).
Do not connect in series , as this will damage the motherboard, which does not support voltages above 4.5V.
Only 3.7V batteries are compatible. Connect the positive terminal of the battery to the pad marked B+ and the negative terminal to B- .
If the terminal voltage exceeds 4.5V, the module may be damaged.
Due to the compact size, heat generated at high power outputs is a normal phenomenon. Ensure adequate ventilation of the module during use.
To change the battery capacity, which limits charging time, see the picture below with the necessary changes. The module comes factory set to a maximum capacity of 10.000mAh , which can be changed to 20.000mAh and 30.000mAh , although the module learns over time to recognize higher capacities.
