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.

Feedback Reviews

1. Nice Buck Converter, meter is amazingly accurate for this price
2. 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
