【18650 Lithium Battery Shield V8】

This module is a portable mobile power supply that supports 3V / 1A and 5V / 2.2A two voltage outputs!
5V voltage output rated current is 2.2A, maximum support 3A current (not recommended for overload, easy to damage the module, speed up the service life), the output of current depends on the quality of the 18650 battery!
MICRO USB charging current 600mA-800mA,
Supports up to two 18650 batteries. It is recommended to use two 18650 batteries, which can be longer!

Special attention: the installation of the battery must be determined positive and negative, the board has been clearly marked positive and negative! Installation errors will burn out the module!

[18650 Lithium Battery Shield V9]

Feature:

Input overvoltage protection, output overcurrent/short circuit protection, charging timeout/overvoltage protection
Output current up to 3A, efficiency up to 95%
With LED identification percentage electricity metering

Parameter:

This power bank supply has a built-in lithium battery protection IC with overcurrent, overvoltage, undervoltage, etc.
USB port output and mobile power board have extended port 3V and 5V output ports to facilitate customer needs and use, greatly reducing the problem of fewer ports
The 4-level LED light shows the power. The default power-on is always working. It needs to be manually turned off. (If you need to change to the non-working state automatic shutdown mode, just cut the middle line of the “NC” bit or remove the “ROUT” resistor. can)
1.8A charging 3A discharge high integration mobile power IC
Motherboard size: 99.98 * 96.24 * 21mm (L*W*H)
Input port: MICRO USB, type-C, wide voltage, up to 6.5V input
Input requirements: 5V constant voltage power supply can be used as charging power input, matching charger 5V1A or above
Output port: USB or expansion port
Output parameter 5V/3A or 3V/1A
Conversion efficiency up to 95% (high conversion rate)
Working temperature: -20 -70 °C

Usage Instruction:

Click to boot
Long press the button to shut down
4 way LED power status indication, automatically turn off the lights after 3 seconds, the battery is less than 3V alarm 6 under protection, less than 2.4 V full stop, no action
Battery current is as low as 3μA after standby
Intelligent input and output, don’t worry about charging time is too long

Application:

Power Bank
Other battery powered devices

Precaution:

Do not reverse the positive and negative, human factors cause damage at your own risk, do not reverse
The battery voltage works normally at 3.2V-4.2V. Do not connect the batteries in series. The series connection will increase the voltage. If the battery capacity is increased, the battery can be connected in parallel. Do not connect in series.
When the battery is reinstalled, the chip may detect the power-off protection mechanism. It needs to be recharged and activated. This is normal!

Package Included:

1 * ESP32S WeMos 4 PCS 18650 Lithium Battery Charging Shield Board
