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.

This is a great little converter that is very accurate. I charge my project battery with it then simply turn it around and run my project with the proper voltage required and set the current limiting for protection.
