This module is the perfect starting point if you are looking to build your own power bank.

This module is ideal for 18650 batteries, 65mm long with the flat top. In the event that you use:

• old batteries
• different capacities
• differnet brands

Please ensure that they are at least above 3.5V each

Not ideal to be used on batteries that have been too far depleted.

After the battery is installed, plug in the charger to activate the battery before use.

The real world conversion rate of a new "real capacity" battery is about 80%. Because there is a line loss of the connection line. Estimation of mixed batteries or "budget" batteries are near impossible to estimate.

For peak use, first allow the battery to fully discharge before charging it.

Note: Reversing the polarity of the battery will burn the module.
