Battery Charger / Power Supply

This is a nice inexpensive down converter that can be used for a power supply or a battery charger.
Check this idea out: You can charge your project battery with this module then simply turn it around and run your project using the converter as the power supply. In this way you can set it to any voltage for the project and add the amount of current limiting you need to be safe. You probably don’t need a fuse on the battery anymore.

Rechargeable lithium-ion battery

When the lithium-ion battery voltage is relatively low, if the direct use of constant voltage charging, the voltage difference due to the larger, leading the charge current is too large, resulting in damage to the battery, so when you want to start using the constant battery current charging, when the charge to a certain extent automatically switches back when the constant voltage charging.

Module above indicated IN-(input negative), IN+(positive input), OUT-(negative output), OUT+(positive output) must be connected to the right, otherwise may cause damage to the module.
