★MULTIPLE PROTECTION: Micro USB lithium ion / lipo / 18650 charging board with overcharge, overdischarge and overcurrent protection, other features include current monitor, under voltage lockout, automatic recharge.
★MULTIPLE CHARGING METHOD: This module is made for charging rechargeable using the constant-current/constant-voltage (CC/CV) charging method, charge port can take power from USB.The input has a MINI USB socket, which can be used to directly charge with the mobile phone charger, and still retains the input voltage wiring solder joints, which can be very convenient DIY.
★ADJUSTABLE CHARGING CURRENT: The charge current can be modeled externally with the Rprog resistor R3.
★DRIVE LOAD: OUT+ and OUT- can be connected to the load, such as the booster converter module/buck converter module or other loads.
