HOW TO USE THE 134N3P USB 5V LITHIUM BATTERY CHARGER/DISCHARGE BOARD
Product Description:
This module is an all-in-one (1S) Li-ion battery charger, Battery Management System (BMS), and Boost converter. It accepts charging power through USB on its Mirco USB connector with a maximum charging current of 1A.
A (1s) Li-Ion battery is connected through the B+ and B- PCB terminals. The module has BMS to protect the battery from overcharge, over-discharge, short circuits, and overload. Additionally, this module supports trickle mode and zero voltage charging which means you can charge fully depleted cells.
The module has a boost converter that can step up the battery voltage to 5V. This 5V supply is output to a USB type A female connector. The setup of this module is perfect for power bank applications.
