If you're not using a battery holder, you may need to solder the battery connections directly to the module. Connect the positive terminal of the first battery to the B+ (Battery Positive) terminal on the module and the negative terminal to the B- (Battery Negative) terminal. Repeat this for the second battery.
Connect the Module:
Identify the input and output terminals on the Dual Micro USB 3.7V to 5V 2A Power Bank module.
Connect the module's input terminals to the positive and negative terminals of the 18650 batteries. These modules often have labeled terminals for battery input.
Connect the module's output terminals to a USB port. This will serve as the output for charging your devices.
Test the Power Bank:
Before assembling everything into the enclosure (if you're using one), test the power bank to ensure it's functioning correctly. Connect a device to the USB output and check if it charges.
Make sure the module's switch (if it has one) is in the "on" position.
Assemble the Power Bank (if using an enclosure):
Place the module inside the enclosure and secure it. Ensure the USB ports are accessible.
If the module has a button or switch, make sure it is also accessible through the enclosure.
Final Testing:
Connect your power bank to a device and ensure it charges properly. You may also want to check the power bank's capacity using a multimeter.
Charge the Power Bank:
Charge your power bank using a USB charger. Make sure the module's charging circuit is functioning correctly.
Label and Customize:
Label your power bank with its capacity or any other information you find useful.
Customize the enclosure, if desired, with LED indicators or other features.
